Frequently asked questions
- Are my PDFs uploaded to a server?
- No. Your signature is drawn and stamped entirely inside your browser. Your files never leave your device.
- Is this a certified digital signature?
- No. This tool stamps an image of your handwritten signature onto the page. It is a visual signature, not a cryptographic digital signature, and it doesn't verify your identity.
- Can I sign multiple pages?
- Each run stamps one page. To sign several pages, run the tool again on the downloaded file.
- How do I get a clean-looking signature?
- Sign slowly in the large box. The image is scaled down when stamped, which smooths out small wobbles.
- Is there a file size limit?
- Each PDF can be up to 50 MB. Processing happens on your device, so very large documents depend on your device's memory.
