How to sign a PDF online
Upload the PDF you want to sign
Drag your file or click to select it from your computer.
Draw your signature
Use your mouse or finger (on mobile) to draw your signature on the panel. You can erase and redo it as many times as you need until it looks the way you want.
Place the signature and download
Choose which page and position you want to stamp the signature on, and download your signed PDF. The process is 100% private, with nothing uploaded to any server.
Why sign your PDFs on PDFDocks?
Signing a document implies, almost by definition, a contract, an agreement, or something with formal validity — exactly the type of file you least want to upload to an external server. On PDFDocks, the signature is drawn and placed with JavaScript, directly in your browser: the document never leaves your device. You draw your signature with your mouse or finger, adjust it until it looks the way you want, choose which page and position to place it on, and download the signed PDF without it ever passing through a server. It's important to clarify that this is a drawn signature (visual), not a digital signature certified with reinforced legal validity — for that you would need a recognized digital certificate.
Is a digital signature legally binding?
+
Yes. Your file is never uploaded to a server: the signature is drawn and placed directly in your browser with JavaScript, so the PDF never leaves your computer.
Is it a digital signature with certified legal validity?
+
No, it's a drawn signature that is visually embedded in the document. For a digital signature with reinforced legal validity, you would need a recognized digital certificate, which this tool does not manage.
Is my PDF uploaded to a server when using this tool?
+
No. The entire process happens in your own browser, with your file never traveling over the internet at any moment.
Can I sign multiple documents at once?
+
Yes, no installation needed. It works directly from your browser, on desktop or mobile, without creating an account or downloading additional software.
Will signing increase file size?
+
Yes, you can delete it and redraw it as many times as you need before placing it in the document.
Do I need a certificate?
+
Yes, you can choose both the page and the exact position where you want to place the signature within the document.
