FAQ
Do you keep my signature?
No. The signature and the file stay in your browser, are never sent to a server, and are gone when you close the page.
How do I sign every page?
Place the signature on one page, then press “Copy this page’s items to every page”.
My uploaded signature has a gray background.
Photograph it in good light, without shadows, on white paper, and keep “Remove the white paper background” ticked.
Is an electronic signature legally valid?
It depends on who asks for it. Many accept a signature image on the document; some require a certificate-based digital signature or a specific platform.
Are my files uploaded?
No. The file is read, changed and saved inside your browser. It is never sent to a server and we keep no copy.
Why won’t my file open?
Password-protected or encrypted PDFs can’t be changed here. Open it in an app that knows the password, save an unprotected copy, then try again.
