Sign PDF FAQ
Short answers to common questions.
Is this a legally valid digital signature?
It adds a picture of your signature, like signing a printed page. It is not a certificate-based digital signature. Many everyday documents accept this; check what the receiver requires.
What is the difference between an electronic and a digital signature?
An electronic signature is a mark that shows you agree, such as a drawn or typed signature placed on the page; Sign PDF adds this kind. A digital signature uses a certificate to prove who signed and that the file has not changed since; Sign PDF does not create those.
Is my signature saved anywhere?
No. Your signature exists only in this browser tab while you work and disappears when you close or refresh it.
Can I sign several pages?
Yes. Go to another page and add your signature again. Initials, dates and text can be placed on any page as well.
Can I use a photo or scan of my signature?
Yes. Upload it as a JPG or PNG. White and near-white background is made transparent, so only the ink shows on the page; you can switch this off. A scan or a bright photo of white paper works best.
Can I add the date next to my signature?
Yes. Choose Date to add today’s date in your device’s date format. You can change the text, drag it into place and resize it.
Supported files and current limitations
Works with ordinary, unlocked PDFs. PDFs with fillable form fields or signature permissions are refused rather than changed. Password-protected and damaged files are refused too.
Your PDF is edited directly instead of being rebuilt, so bookmarks, links, attachments and accessibility tags stay in the new file.
Signatures, initials, dates and text are added as images on top of the page. This is a visible signature, not a certificate-based digital signature.
Processing stays on your device with no cloud fallback. Very large files can exceed your device’s memory. Your original files are never changed.
