↗ · Free e-signature software

The best free e-signature software in 2026, limits included.

Five tools that get a document legally signed for $0 on a plan that never expires. The differences are in the caps: how many documents a month, what's watermarked, how long your records are kept. They're all stated below.

↗ · The alternatives

Every tool on this list has a real free plan, not a 14-day trial with a countdown. We ranked them by monthly signing allowance and what the free tier actually includes, and stated each one's catch, ours too: Sign Sail's free plan keeps records for 90 days, and you'll see the same kind of fine print called out for everyone else.

Worth knowing · Competitor pricing and limits were checked against public pricing pages in June 2026. Plans change; verify current numbers before you buy. All prices USD.

01Sign SailThat's us

Free: 2 forms, 1 document, 25 signed submissions/mo

Best for: The biggest free monthly allowance, with the full audit trail

25 signed submissions a month is the largest recurring free allowance on this list, and nothing is held back from the evidence bundle: every free signature carries the SHA-256 audit trail, the PAdES seal, and a signed PDF with no watermark. You also get the form builder and a QR code per form, so a waiver or intake form is one link. The catch: 2 forms, 1 stored document, and records are kept 90 days (export anytime; we email you before anything is deleted).

02SignWell

Free: 3 documents/mo · paid from ~$10/mo

Best for: Free one-off contract sends

A clean upload-and-send tool whose free plan covers 3 documents a month. No form builder or structured data collection, so it suits finished contracts rather than information gathering. When you outgrow it, the ~$10/mo entry plan is one of the cheaper paid steps in the category.

03Dropbox Sign

Free: 3 signature requests/mo

Best for: Occasional signing inside the Dropbox ecosystem

Dropbox Sign's free plan covers 3 signature requests a month, enough for a freelancer signing one or two contracts. The pull is integration: if your files already live in Dropbox, the signing flow starts where the documents are. Past 3 a month you're into per-user pricing from about $15.

04Signaturely

Free: 1 signature request/mo (per their pricing page)

Best for: The simplest possible free send

The most minimal interface of the group, which is the point. The free plan covers 1 signature request a month per their pricing page, so it fits genuinely occasional personal use: a lease here, a release form there. Anything recurring outgrows it in the first week.

05OpenSign

Free, open source (self-hosted)

Best for: Unlimited free signing, if you run the server

The only way to get unlimited free e-signatures: host the open-source OpenSign yourself. The software costs nothing; the deployment, storage, upgrades, and uptime are your job. Right when you have ops capacity and procurement or data-residency rules out SaaS, wrong when 'free' was supposed to mean less work.

↗ · Fair is fair

When a paid plan is the better pick.

  • You send more than a handful of documents a month. Every hosted free plan here caps volume, and at real volume the $10 to $15 entry plans stop being a luxury and start being the honest answer.
  • You need templates, bulk send, or an API. Those are paid features almost everywhere, Sign Sail included: custom templates land on Pro ($12/mo billed annually), the API on Business.
  • You're keeping signed records long-term. Free tiers limit retention, Sign Sail's keeps data 90 days, while paid plans keep it for a year or indefinitely. For documents you may need in a dispute years later, retention is worth paying for.

↗ · Questions

Asked before you switch.

Is free e-signature software legally binding?

Yes. Legal validity under the ESIGN Act, UETA, and eIDAS Simple Electronic Signature comes from how the signature is captured (intent, consent, attribution, record integrity), not from what you paid. Sign Sail's free plan produces the identical evidence bundle to its paid tiers: signer IP, timestamp, SHA-256 hash, and a PAdES-sealed PDF.

What's the catch with free e-signature plans?

One of three things, usually: a volume cap (1 to 25 documents a month across this list), branding or watermarks on your documents, or short data retention. Read the cap that matches how you'd actually use it. A cap of 3 sends a month is fine for occasional contracts and useless for a front-desk waiver form.

Which free e-signature plan is the most generous?

By monthly allowance, Sign Sail: 25 signed submissions a month against 3 on SignWell and Dropbox Sign and 1 on Signaturely. The only unlimited option is self-hosting OpenSign, which trades the subscription fee for server and maintenance work. If you're sending finished PDFs occasionally, any of the 3-a-month tools will do.

Do the people signing need to pay or make an account?

No, on every tool listed here, and that's worth checking on anything else you evaluate. On Sign Sail specifically, signers open a plain link, fill, and sign from any device; there's no login, no app, and no account, on the free plan and every other one.

Legal-grade on every plan.

Every signature carries the signer's IP, a UTC timestamp, the user-agent, a SHA-256 hash, and a frozen copy of the form, baked into a signed PDF. Included at every tier, not sold back to you as an upgrade.
