Free e-signature software is easy to find and hard to compare. Every vendor says “free,” but the word hides a monthly cap, a branding stamp or a missing audit trail. This guide lines up ten options and states, in plain numbers, what each free plan actually gives you.
Every limit and price below was re-checked on the vendor’s own pricing page on October 16, 2026, following the same method we use in how we rank companies. If you already know you need more than a free plan, our PandaDoc alternatives guide compares the paid market, and the Apps section covers everything else we review.
A quick note on method: we opened the vendors’ pricing pages and recorded the free caps and first paid tiers in plain numbers. One exception: OpenSign’s pricing page did not render for us, so its numbers come from the official OpenSign FAQ. Where a vendor’s page was unclear, we say so rather than guess.
The ten free options at a glance
The monthly cap is the number that matters first. Find your volume in this table, then read only the sections that survive it.
| Tool | Free plan gives you | Monthly cap | Paid step |
|---|---|---|---|
| SignWell | 1 sender, 1 template, audit trail | 3 documents | $10/mo |
| Documenso | 10 recipients per document, no card | 5 documents | $25/mo |
| OpenSign | Unlimited signatures, open source | None stated | Paid advanced tier |
| DocuSeal | Legally binding signing, 10 field types | 10 request emails | $20/user/mo |
| PandaDoc | Editor, tracking, 24/7 support | 5 documents | $19/seat/mo |
| Zoho Sign | Workflows, reminders, audit trail | 5 envelopes | $10/user/mo |
| Jotform Sign | 5 forms, 100 submissions | 10 signed documents | $34/mo |
| Smallpdf | 30+ PDF tools, signing via Sign.com | 2 sign documents | $15/mo |
| Adobe fill and sign | Fill and sign your own PDFs in browser | Self-signing only | $12.99/mo |
| SignNow | No free plan, trial only | n/a | $8/user/mo |
One pattern worth knowing before you pick: free plans ration sending, not signing. If other people only need to sign what you send, caps apply to you. When signing becomes one step in a bigger workflow, the automation tools we track can carry the rest of the process.
Two entries need a second look at the table. Smallpdf’s signing now runs through a separate Sign.com account, and SignNow appears because its $8 seat is the upgrade most free users eventually buy. Both are explained in their sections.
Free tool 01
SignWell: three free sends a month, done properly
Free plan: 1 sender, 1 template, 3 documents a month. Audit trail and API included.
Paid step: Light at $10/mo for unlimited documents and 5 templates.
Best for: a freelancer or founder sending a few real contracts each month.
SignWell’s free tier is small but honest. Three documents a month covers a consultant’s client agreements, and the audit trail comes standard rather than hiding behind a paywall.
The paid plans stay friendly too: Light is $10 a month, Business is $30 with three senders included. For contractor paperwork that recurs, pairing SignWell with the tools in our Gusto pricing breakdown keeps the whole admin stack cheap.
- Audit trail included even on the free plan.
- One template only, so pick your most-sent document.
- Extra senders cost $10/mo each on paid plans.
Skip it if you send more than three documents weekly. The cap resets monthly, not daily, so batch your sends or plan to pay.
Free tool 02
Documenso: open source, hosted free, no card required
Free plan: 5 documents a month, up to 10 recipients each, no credit card.
Paid step: Individual at $25/mo billed yearly for unlimited documents.
Best for: casual signers who like open source but want someone else to host it.
Documenso is the newest name here, and its free hosted plan is one of the clearest: five documents monthly, forever, under a published fair-use policy. Signup asks for no card, so there is nothing to cancel.
Because the code is open, the Individual plan at $25 a month billed yearly is a choice, not a trap. Teams planning to wire signing into their own apps should note the API sits on paid plans, which is where our automation tools shortlist becomes relevant again.
- Self-hosting is free if you can run a server.
- Teams plan: $40/mo billed yearly, 5 users included.
- Fair-use policy governs the free tier, so read it.
Five documents with ten recipients each covers most small-team needs. A contract sent to five signers still counts as one document, which makes the cap stretch further than it looks.
Free tool 03
OpenSign: unlimited free signatures if you can handle open source
Free plan: unlimited signatures, both self-hosted and on the cloud free tier.
Paid step: advanced tier adds API access, public links, embedding and validations.
Best for: technical teams who want no document cap at all.
OpenSign is the only option here with no stated monthly limit. The project is open source with more than 7,000 GitHub stars, and even its hosted cloud free tier advertises unlimited signatures.
The catch is everything around the signature. Support is community-led, the polish trails commercial tools, and the features businesses eventually want, like API access and embedding, sit on the paid advanced tier.
- No monthly document cap on the free tier.
- Self-hosting removes the vendor entirely.
- Advanced business features require the paid tier.
If you self-host, you need a server to run it on. Our Render hosting review covers one option teams use for exactly this kind of lightweight deployment.
Free tool 04
DocuSeal: ten free sends and a free API sandbox
Free plan: legally binding signing, 10 field types, 10 request emails a month.
Paid step: Pro at $20/user/mo or $200/yr for unlimited requests.
Best for: light business sending, and developers testing integrations.
DocuSeal’s Basic plan covers the full signing loop: upload, place fields, send, collect a legally binding signature. Ten request emails a month is the most generous sending cap on this page.
Developers get a second gift: the API sandbox is free and unlimited for testing, with production signing at $0.20 per document. Teams plumbing signatures into Salesforce should also read our Salesforce integration tools guide before choosing where the integration lives.
- 10 request emails monthly is the highest free cap here.
- API sandbox is free for development and testing.
- Self-hosted open source edition available.
One detail worth testing: request emails, not documents, are the capped unit. A document sent to three signers spends three of your ten monthly emails, so single-signer documents go furthest.
Free tool 05
PandaDoc: the free eSign plan inside a proposal suite
Free plan: 5 documents a month, drag-and-drop editor, real-time tracking, 24/7 support.
Paid step: Starter at $19/seat/mo on annual billing.
Best for: sales documents you expect to outgrow free quickly.
PandaDoc’s free eSign plan is the most polished free tier here. You get the real editor, tracking that shows when a recipient opens the document, and round-the-clock support, all for five documents a month.
Choose it when the documents are sales-facing and an upgrade is likely. When that day comes, our PandaDoc alternatives guide compares its paid plans against ten rivals so you upgrade with open eyes.
- Tracking and notifications included on free.
- Five documents a month, not sixty a year as once listed.
- Limited API access on the free plan.
The free plan also makes a capable trial: everything you build stays in your account if you upgrade, so templates and contacts carry over rather than starting from zero.
Free tool 06
Zoho Sign: a real free plan inside the Zoho world
Free plan: 1 user, 5 envelopes a month, workflows, reminders and audit trail.
Paid step: Standard at $10/user/mo billed annually, 25 envelopes per user.
Best for: anyone already running on Zoho apps.
Zoho Sign’s free edition does not feel stripped. Signature workflows, reminders and the audit trail are all in, and the mobile and desktop apps work on the free plan too.
The obvious home is a business already using Zoho CRM, where signing hooks straight into deals; our easy CRM platforms for small sales teams guide covers that pairing. At $10 per user per month, the Standard upgrade is also the cheapest full tier on this page.
- Five envelopes a month, one user only.
- Workflows and reminders included on free.
- Standard upgrade is just $10/user/mo annually.
Outside Zoho’s world the free plan still works fine as a standalone signer. You just will not use the integrations that make it special, so solo users may prefer SignWell’s simpler setup.
Free tool 07
Jotform Sign: ten signed documents for form-driven teams
Free plan: 5 forms, 100 monthly submissions, 10 monthly signed documents.
Paid step: Bronze at $34/mo billed annually.
Best for: HR and operations teams collecting signed forms.
Jotform Sign treats a signature as the last field of a form. If your documents are intake forms, waivers or onboarding packets, that model fits naturally, and ten signed documents a month is a workable free allowance.
HR teams running offer letters through the applicant tracking systems we review will find Jotform Sign covers the signature step for free. Jotform branding appears on the free plan, which is the main reason to upgrade.
- 10 signed documents a month on the Starter plan.
- Jotform branding shows until you pay.
- Flat account pricing, not per seat, on paid plans.
The 100 monthly submissions limit rarely bites before the ten-signature cap does. Watch the signature number; it is the one that runs out first.
Free tool 08
Smallpdf: PDF chores first, signing second
Free plan: 30+ PDF tools with daily limits; e-signing via Sign.com, 2 documents a month.
Paid step: Pro at $15/mo for unlimited tools and signing.
Best for: people whose real job is PDF wrangling, with occasional signing.
Smallpdf is a PDF toolbox that also signs. The free account covers compress, convert, merge and edit with daily limits, which makes it the best companion to the PDF editor apps we compare elsewhere.
The signing side changed recently: e-signatures now run through Sign.com, and the free allowance there is just two documents a month. Treat Smallpdf as your PDF workbench, not your sending tool.
- Only 2 sign documents a month via Sign.com.
- Daily download limits apply across the tools.
- Pro at $15/mo unlocks everything, including signing.
The daily limits reset every 24 hours, which suits occasional use. If you compress and convert PDFs every day, the free tier will frustrate you within a week.
Free tool 09
Adobe online fill and sign: the fastest way to sign your own PDF
Free plan: fill and sign your own PDFs in the browser, no install.
Paid step: Acrobat Standard at US$12.99/mo for editing and sending.
Best for: one-off self-signing: a form, a permission slip, a lease.
Adobe’s online fill and sign tool does one job and does it instantly: drag in a PDF, fill the fields, draw your signature, download. The file is deleted from Adobe’s servers unless you sign in to save it.
It cannot send a document to someone else for signature, so it pairs well with everything else on this list. If your PDF first needs cleanup or conversion, our PDF to Word guide covers that step.
- No account needed for a quick sign-and-download.
- Sending for signature requires a paid Acrobat plan.
- Files are deleted unless you sign in to save.
Keep this one bookmarked for emergencies. When a landlord or school emails a form that needs a signature today, it is the fastest free route from PDF to signed copy.
Free tool 10
SignNow: not free, but the cheapest proper upgrade
Free plan: none; there is a trial instead.
Paid step: Starter at $8/user/mo billed annually, the cheapest seat we track.
Best for: the moment your free cap runs out every month.
SignNow makes this list as the escape hatch. When three or five free documents a month stops being enough, $8 per user per month on annual billing is the lowest price for a full signing tool we have verified.
Monthly billing jumps to $20, so commit annually or stay free. Pair it with the follow-up workflows in our AI email automation tools guide if chasing unsigned documents eats your afternoons.
- Cheapest full plan here at $8/user/mo annually.
- Monthly billing more than doubles the price.
- Unlimited users and templates even on Starter.
Use the trial to send real documents first. If the workflow fits, the annual Starter plan costs less per month than two coffees and removes every cap on this page.
Know the limits
What “free” actually covers: sign, send, store, prove
Four jobs hide inside e-signature software, and free plans cover them unevenly. Knowing which job you need tells you which cap matters.
- Sign: putting your own signature on a PDF. Adobe and Smallpdf do this free.
- Send: asking someone else to sign. This is what monthly caps ration.
- Store: keeping the finished document. Check export options before you need them.
- Prove: the audit trail. It is what makes a signature worth having in a dispute.
The audit trail is the item people forget. A completion certificate that records signer, time and document identity is what turns a scrawl into evidence, so confirm your free plan includes one before you rely on it. Teams embedding signatures in a sales motion should also think about the surrounding flow: our marketing automation platforms guide covers what happens before and after the document.
Storage deserves one more sentence. Free plans keep your documents, but export habits vary: download signed copies monthly so a lapsed account never locks away a contract you need.
Vendors do make the caps findable when you look. DocuSeal’s pricing page, for example, states the free plan’s ten request emails and legally binding signing in plain view, which is exactly the honesty worth rewarding.
Your call
Open source or hosted: the real trade-off
Three tools here, OpenSign, Documenso and DocuSeal, can be self-hosted for free with no document limits. That is a genuinely different deal, and it suits a specific buyer.
Self-hosting gives you data control and no vendor caps. It also hands you updates, backups, email deliverability and security patches. A small team without a technical person is usually safer on a hosted free plan.
If signatures feed a sales process, sort the process before the tool: our piece on why CRM projects fail explains the adoption traps, and Pipedrive alternatives covers CRMs with document features built in. The signing tool should be the last decision, not the first.
There is also a middle path. Start on a hosted free plan, learn your real volume for a quarter, then self-host only if the numbers and the skills both say yes. Whatever you decide, decide it on a real document: send your actual contract through a test run before you move the whole archive over.
Next steps
How to choose in five steps
- Count your documents. Your monthly send volume eliminates half this list instantly.
- Decide sign or send. Signing your own PDFs is free everywhere; sending is capped.
- Check the audit trail. No certificate, no contract protection.
- Test two tools with a real document. Send it to yourself and a colleague.
- Write down the limits. Free tiers change; re-check them every quarter.
For the admin work that surrounds signing, our guides to employee scheduling software and the rest of the Apps section keep the whole back office on the same cheap footing. Whatever you pick, run the five steps above with a real contract this week; an hour of testing beats a month of reading.
Frequently asked questions
Q: What is the best free e-signature software?
For sending a few contracts, SignWell’s free plan is the most complete. For unlimited volume with technical help, OpenSign. For proposal-style documents, PandaDoc’s free eSign tier. The right answer depends on your monthly volume, so count your documents first and let the cap choose for you.
Q: Is free e-signature software legally binding?
Yes, when the tool records proper intent and consent. Laws like the US ESIGN Act and the EU’s eIDAS regulation treat electronic signatures as valid, and every tool here produces them. Keep the audit trail; it is your proof if a signature is disputed. For high-value contracts, ask a lawyer whether your jurisdiction needs anything beyond a standard e-signature.
Q: How many documents can I send for free each month?
From our October 2026 check: SignWell 3, Documenso 5, Zoho Sign 5, PandaDoc 5, Jotform Sign 10, DocuSeal 10 request emails, and Sign.com via Smallpdf 2. OpenSign states no limit on its free tier. Remember that sending is what is capped; signing documents others send you is free everywhere.
Q: Is open source e-signature software safe?
The code being inspectable is a real security plus. The risk is operational: a self-hosted server you do not patch or back up is less safe than a vendor’s hosted free plan. Choose self-hosting only if someone owns its upkeep. For everyone else, a reputable hosted free plan with a published security page is the safer default.
Q: Can I sign my own PDF for free without sending it anywhere?
Yes. Adobe’s online fill and sign tool and Smallpdf both let you upload, sign and download in the browser. These are built for signing your own documents, not for collecting signatures from other people. For anything confidential, check the vendor’s retention note first; Adobe deletes your file unless you sign in to save it.
Q: What happens when I hit the free limit?
The tool asks you to upgrade or wait for the next month. Your existing signed documents stay available in every tool we checked. If you hit the cap two months running, SignNow at $8/user/mo annually is the cheapest full plan we verified, with SignWell Light and Zoho Sign Standard both at $10 close behind.
Q: Do free plans include an audit trail?
Most on this list do, including SignWell, Zoho Sign and PandaDoc. Always confirm the completion certificate exists in your test send, because that document is what protects you if a signer later denies signing. Make downloading the certificate part of your routine, not something you search for during a dispute.
