AdFrequently Asked Questions
How do I sign a PDF online?
Upload your PDF, create your signature by drawing, typing your name, or uploading a transparent PNG, then click anywhere on the page to place it. Drag and resize to fit, then download the signed PDF.
Do I need an account, and is my signature saved?
No account or sign-up is needed. Your signature is stored only in your browser's memory for the current session and is discarded when you close or reload the page.
Can I sign more than one page?
Yes. Use the page navigation to move between pages and place the same signature or separate initials anywhere you need them across the document.
Is my file uploaded to a server?
No. Everything runs entirely in your browser using pdf.js and pdf-lib. Your PDF and signature never leave your device.
How is the signature added to the document?
The signature is flattened directly into the page content, so it becomes a permanent part of the PDF rather than an editable annotation layer.
