Sign PDF online

Yes, our PDF signature tool offers a free version. It allows you to upload up to 2 PDF files per day (maximum size: 3 MB each). For more advanced features, paid options are available.

Yes. An electronic signature has the same legal value as a handwritten signature. In the United States and Europe, the E-Sign Act and eIDAS regulations, for example, recognize their validity, including in an international context.

Absolutely. We use 256-bit SSL encryption to guarantee the security of your digital files. Each digital document is accessible only via a secure personal link. All files, signatures, forms and texts are automatically deleted from our servers after 24 hours.

Yes, our tool allows multiple people to sign documents online together, in the same file. You can add multiple signature (or initials) fields, define their location on the page, and each signer will receive an email notification to sign electronically. Once everyone has signed, a confirmation e-mail will be sent to you.

Yes. Our online tool is compatible with every device, from mobile phones to tablets. You can add a signature to PDFs with your finger, a stylus, or import an image of your electronic signature.

The sender has full access: they can convert a document, add a signature field and select the signers. A real-time monitoring system also shows who has and hasn’t signed yet. As soon as a signer has completed the form, an email alert is sent to the sender. For their part, signers can only sign documents online and view the documents received, without being able to edit them.

Of course. There are several options to personalize your electronic signature in PDFs:
- Type your name
- Sign a PDF document online with your finger or a mouse
- Import an image in PNG, JPG or SVG format
You can then select the precise location on the PDF page or form where you wish to place your signature or initials.
To personalize your document, you can also add:
- Text fields
- Fields for initials
- Date fields
- Interactive forms to place in the desired field

If you have a file in Word, Excel or image format (JPG, PNG, SVG, etc.), our tool lets you automatically convert it to PDF so that you can add signature fields. You can then sign it, have third parties sign it, and download or e-mail it.

Yes. Whether you're using Adobe Acrobat or any other PDF editing application, you can import your documents, add fields, have them signed electronically, then download or share them. Our PDF signature tool is designed to be integrated easily into your existing workflows.

Yes. When you add a signature to a PDF, the document then contains a footer with traceability information: signer's name, IP address, date and time of signature. This transparency reinforces the legal security of your digital document and the validity of its electronic signatures.
