Is Signature PDF (pdf.24eme.fr) Free to Use?

Updated

Yes. Signature PDF is described on its own site as "Free open-source software for signing and manipulating PDFs," released under the AGPL-3.0 license. The site lists no prices, subscriptions, or payment platforms, and there is no indication of premium tiers or paid add-ons. The practical condition to keep in mind is that the tool runs in the browser and the site states it is "not functional without JavaScript enabled," so you need JavaScript turned on to use it at all.

What "free" means here

Two separate things are worth distinguishing:

  • No cost to use. Nothing on the site suggests a fee, account upgrade, or paywalled feature. Every listed function appears available without payment.
  • Open source. The software is published under AGPL-3.0, and the site links to its source code. That means the code can be inspected, reused, and modified under the terms of that license — a different kind of "free" than simply costing nothing.

Because no pricing page, checkout, or payment provider is referenced, there is also no evidence of a hidden charge buried behind a sign-up step. That said, absence of pricing signals is not the same as a guarantee about every future feature; it reflects what the site currently states.

What you can do without paying

The homepage groups the free tools into four areas:

Category Included actions
Sign Add a signature, initials, or a stamp; type text; strike through text; allow multiple people to sign via a shared link; sign with the server certificate; add a watermark
Organize Combine PDFs, reorder pages, extract pages, rotate pages, change or standardize paper size, delete pages, generate a booklet, convert images to PDF
Metadata Add, edit, or remove PDF metadata; OCR text detection in images inside a PDF
Compress Compress and reduce PDF file size

The multi-signer option is notable for a free tool: it lets several people sign the same document through a shared link rather than requiring each person to install software.

Conditions and things to check yourself

  • JavaScript is required. The site explicitly says it will not function without it, so a script blocker or a locked-down browser will break the tool.
  • Server certificate signing. One signing option uses the server's certificate. If your situation requires a specific personal or organizational certificate, confirm that this option matches your requirement before relying on it.
  • Sensitive documents. The site does not state its data-handling or retention practices in the material available here. For confidential contracts or personal data, review its privacy terms yourself before uploading.
  • License obligations. AGPL-3.0 matters mainly if you plan to reuse or modify the code, not if you are just signing a PDF.

If your question is simply "will I be charged to sign or compress a PDF here," the answer is no, based on everything the site presents.
