Apposer une signature manuscrite sur votre PDF
iSharePDF's Sign PDF tool lets you add your signature to any PDF document directly in your browser. Draw your signature with a mouse or touchscreen, type it in your preferred font, or upload an image of your handwritten signature, then place it anywhere on the page with a click.
Your files never leave your device. All processing happens locally in your browser using client-side JavaScript, no server upload, no cloud storage, no account required. Your documents stay yours, start to finish.
Sign PDF is useful for freelancers countersigning client contracts, employees returning HR forms and onboarding documents, and individuals signing lease agreements, loan paperwork, or administrative forms sent by government offices, all without needing Adobe Acrobat or a paid e-signature service.
In most countries, electronic signatures on PDF documents are legally binding for the vast majority of contracts and agreements. In the EU, they are recognized under the eIDAS regulation; in the US, under ESIGN and UETA. For high-stakes documents requiring a qualified electronic signature (QES), such as certain real estate deeds or notarized instruments, a certified provider may be required. For standard business contracts, employment forms, and everyday agreements, a drawn or typed signature added to a PDF is fully enforceable.
Yes. The tool works in any modern mobile browser, Chrome, Safari, Firefox, on iOS and Android. You can draw your signature with your finger directly on the touchscreen, which often produces a more natural result than using a mouse on desktop.
No account, no registration, no email address. You open the page, drop your file, sign it, and download it. There is nothing to sign up for and no information collected about you or your document.
If the PDF has an owner password restricting editing but can still be opened normally, the tool will typically be able to overlay a signature. If the document requires a password just to open (user password encryption), you will need to enter that password or decrypt the file first using the iSharePDF Unlock PDF tool, then return to sign it.
Signing a PDF adds a visible signature element, your name, initials, or drawn mark, to the document. Certifying (or applying a digital certificate signature) embeds a cryptographic certificate that verifies the signer's identity and detects any subsequent modifications to the file. iSharePDF's Sign PDF tool handles visible signatures, which covers the needs of most everyday documents. If your workflow requires verifiable cryptographic certification with a certificate authority, you will need dedicated software such as Adobe Acrobat Pro or a qualified trust service provider.
