Konvizi’s “Sign PDF” tool is free, with no sign-up, no watermark and no file limit. All the processing happens in your browser, on your device: your files are never uploaded to a server, which makes it suitable for personal and confidential documents.
Drag your PDF file into the area above or click “Choose files”.
Click “Add signature”, draw it, then drag it to the right spot. The dot in the corner makes it larger or smaller.
Click “Download PDF”: the signature is written into the document, on your device.
A contract, a quote or a form to send back signed? There is no need to print, sign and scan. Draw your signature with your mouse or finger, place it in the right spot, add the date if needed, and send the PDF back. Neither the document nor your signature leaves your device.
PDF is the universal document format: it looks the same on every device, keeps its layout and prints without surprises.
Contracts, payslips, bank statements, tax returns: PDFs often hold sensitive information. With Konvizi they never leave your device, are stored nowhere and read by nobody. Most PDF tools copy pages without recompressing them: selectable text, links and quality are preserved.
Your files never leave your device. No upload, no storage.
No upload and no queue: the conversion starts right away.
As many files as you like, with no imposed size limit.
No sign-up, no watermark, no subscription.

Yes, completely. No sign-up, no watermark, and no maximum number of documents.
No. Everything happens in your browser, on your device. Your files are never sent over the internet: nobody but you can see them.
It is a drawn signature, the equivalent of a scanned handwritten signature. It is accepted for many everyday documents, but it is not a certified digital signature: for a document that requires one, use a qualified e-signature service.
Yes. “Add text” lets you write the date, your name or a note. To sign another page, scroll to it, click “Add signature” again, then “Reuse my signature”.
Open your browser’s developer tools (F12 key), go to the “Network” tab and run a conversion: no request carries your file. The site also enforces a security rule (Content-Security-Policy) that forbids the browser from contacting any site other than konvizi.com, and konvizi.com is a static site with no service able to receive files.
Yes. Konvizi works in the browser of your phone or tablet (Safari, Chrome…) just like on a computer, with no app to install. Very large files are processed faster on a computer, which has more memory.
