Free electronic signature: 2026 comparison
Looking to sign documents online without paying? Several solutions offer a free plan, but their limitations vary considerably. This guide compares the options available in 2026 to find the best free electronic signature for your needs.
What is a free electronic signature?
An electronic signature is called "free" when you can use it without paying to sign or have a document signed. Three categories of free plans coexist in 2026, and their legal and operational implications are quite different: (1) time-limited trials (DocuSign 30 days, Yousign 14 days) that force a paid migration afterward; (2) permanent plans but limited to simple signature level SES (PandaDoc, some Dropbox Sign offerings), often legally sufficient but without identity verification; (3) permanent plans with advanced AES eIDAS signature included (Certyneo), which combine free access, enhanced evidential value and EU hosting.
The main legal criterion is not free access itself but compliance with eIDAS regulation (EU) No 910/2014. The three levels defined by eIDAS — simple signature (SES), advanced (AES) and qualified (QES) — are all admissible in court, but their evidential weight differs. A free SES with complete timestamped audit trail has probative value equivalent to that of a handwritten signature for the majority of private contracts (quotes, NDAs, commercial agreements). For HR contracts, real estate mandates or significant invoices, AES is recommended as it adds identity verification (OTP SMS or email).
The second criterion is data sovereignty. US solutions (DocuSign, Adobe Acrobat Sign, PandaDoc, Dropbox Sign) are subject to the CLOUD Act, which lets a US court demand access to your contracts even when they are hosted in Europe. European solutions (Certyneo, a French company hosting in the EU; Yousign and Universign in France) fall outside that scope. For professional use in the EU, the “free + AES + EU hosting” combination offers the best value-legal-protection ratio. That is exactly what the Certyneo free plan offers, detailed below.

Which free plan according to your profile?
Free electronic signature does not serve the same needs depending on whether you are a freelancer, association, or SME. Here's how to choose.
Freelancer / independent
You send a few quotes and contracts per month, mainly to recurring clients. Your priorities: signing speed and professional evidence quality, without paying for enterprise features you don't need.
Recommendation : Certyneo free plan (5 envelopes/mo for 14 days, then 2/mo, AES included)
Association / cooperative
You sign general assembly minutes, partnership agreements, and prefecture forms. Multiple co-signers (president, treasurer, secretary) often need to sign the same document, and traceability is essential for your auditors.
Recommendation : Certyneo free plan (unlimited co-signers)
SME / small business (< 25 contracts/month)
You manage employment contracts, invoices, and quotes for 1 to 10 employees. Volume remains manageable, but you need AES for HR documents and EU hosting for your customer data.
Recommendation : Free plan + upgrade to Personal plan €9/month above 5
Send a document to sign online for free
Sending costs envelopes, signing doesn't cost any. It's the only rule to know: your recipient pays nothing, doesn't create an account and doesn't install anything. Here's what exactly the free plan covers on the sender's side.
It's the sender who pays, never the signer
The quota is deducted from the account that sends. Your customers, your candidates or your suppliers receive a secure link by email and sign from their browser, on mobile as on desktop, without registration.
What the free plan allows you to send
5 envelopes the first month, then 2 per month, in simple signature (SES) compliant with eIDAS and without a credit card. An envelope can contain multiple documents and multiple signers: a contract signed by three people remains a single envelope.
Follow up and remind without paying extra
Each send displays its status in real time — received, opened, signed — and you can remind a signer who is dragging their feet. The signed document and its timestamped proof file are downloadable from the last signature.
When free is not enough
Beyond the quota, or as soon as you need SMS authentication (AES), reusable templates or batch sending, the first paid plan starts at €9/month for 25 envelopes. Nothing is lost between the two: the same account, the same documents.

Questions about free electronic signature
- Is there really a free, permanent electronic signature?
- Yes, Certyneo offers a permanent free plan (no expiry). DocuSign and Yousign only offer temporary trials (30 and 14 days). PandaDoc offers a free plan but without AES or EU hosting.
- Does a freely signed document have legal value?
- Yes, if the solution is eIDAS-compliant. Certyneo generates timestamped signature evidence compliant with eIDAS even on the free plan. The audit trail constitutes acceptable evidence in court throughout the EU.
- Can I sign for free without creating an account?
- Signatories never need to create an account. Only the sender needs to create a free account.
- Is data secure on a free plan?
- Yes. At Certyneo, the security level (TLS 1.3, AES-256 encryption, EU hosting) is identical regardless of the pricing plan.
- What is the best free electronic signature in 2026?
- The criterion that best distinguishes offers is not the free volume but the combination "permanent plan + eIDAS AES compliance + EU hosting". On this trio, Certyneo is the only solution to offer it for free in 2026: 5 envelopes/mo for 14 days, then 2/mo without expiration, advanced AES signature with OTP, EU hosting outside the Cloud Act. DocuSign and Yousign only offer temporary trials (30 and 14 days), PandaDoc limits to SES level, and Adobe Acrobat Sign starts at 7 days trial. For a volume above 5 contracts/month, the Personal plan at €9/month remains 2 to 4× cheaper than equivalent competitors.
- Does a free electronic signature really have legal value?
- Yes, provided the solution complies with eIDAS regulation (EU) 910/2014. A simple SES signature issued by a qualified provider and accompanied by a complete timestamped audit trail is admissible as evidence in all 27 EU Member States. Its probative force is equivalent to that of a handwritten signature for common private contracts. For HR contracts, real estate mandates, or public procurement, an advanced AES signature (identity verification by OTP) is recommended — included free at Certyneo, on subscription with competitors.
- Can I use a free electronic signature for my professional activity?
- Yes without restriction. The Certyneo free plan does not distinguish between personal and professional use: you can sign client quotes, supplier contracts, mandates, commercial agreements, payslips, and partnership agreements. The only limit is monthly volume (5 envelopes/mo for 14 days, then 2/mo). An envelope can contain one or more documents and be addressed to one or more signers, which covers the majority of freelancers, associations, and SMEs who send fewer than one signature per week.
- What is the difference between free and paid electronic signature?
- The difference lies in 4 areas: (1) monthly volume — free = 5 envelopes/mo for 14 days, then 2/mo, paid = 25 to several hundred; (2) number of sending users — free = 1, paid = multi-user teams; (3) enterprise features — REST API, webhooks, SSO, CRM/HubSpot/Slack/Salesforce integrations are reserved for paid plans; (4) support — standard email on free, priority or dedicated on enterprise plans. Legal value and security level are however identical (TLS 1.3, AES-256, EU hosting) across all Certyneo plans.
- Does the recipient need to create an account to sign my document?
- No. They receive a secure link by email, open the document in their browser and sign — without registration, without installing an application and without paying anything. Only the sender needs a Certyneo account.
- How many documents can I send to sign for free?
- 5 envelopes the first month, then 2 per month with the free plan. An envelope can group multiple documents and multiple signers, which goes further than it seems: a contract signed by three people uses only one envelope.
