Why sign a PDF online instead of printing it?
The classic "print → sign by hand → scan → send back" workflow takes 15 minutes on average, wastes paper, and produces a document of lower quality than the original. Digital signing does the same thing in 30 seconds, with no printer, and the final document stays as clean as the source PDF.
ModySign protects your privacy by doing all the work in your browser: your PDF is never uploaded and your signature is never sent over the internet. It is technically impossible for us to read your documents — signing and merging happen client-side with pdf-lib.
For professional cases that require legally binding signatures (commercial contracts, leases, signed quotes), use a ModySign account: the eIDAS audit trail (timestamp, IP, document hash, signer email validation) is generated automatically and accepted by French and European courts.
Questions fréquentes
Is the electronic signature from this tool legally valid?+
For personal use or internal documents, yes — it's a simple electronic signature that's admissible as evidence. For full legal weight (eIDAS level 1+), create a ModySign account: we automatically generate the audit trail (timestamp, IP, hash) that makes the signature admissible in court.
Is my PDF sent to your servers?+
No, never. Everything happens in your browser thanks to pdf-lib and pdfjs-dist. Your PDF and your signature stay on your machine.
How many pages can I sign in the free version?+
The free tool displays up to 5 pages to keep browser memory usage in check. To sign longer PDFs or place multiple signatures at different positions, create a ModySign account (14-day free trial).
Can I have someone else sign my PDF remotely?+
That's a premium feature: create an account, upload the PDF, add the signer's email, they receive a secure link to sign from their browser. You get back the signed PDF plus the eIDAS audit trail.
My scribble looks like my real signature — is that enough?+
For everyday use (freelance contract, internal agreement, quick approval), yes. For formal cases (notarial deeds, public tenders), you need an advanced or qualified signature — ModySign covers the simple eIDAS signature, which is enough for 95% of business cases.
