Sign PDF
Draw, type or upload your signature and place it on any page.
Your signature is added to the PDF as an image (a visible signature). This is not a qualified or advanced electronic signature: there is no identity check and no certificate.
This PDF contains a digital signature. Any change to the file – including an added signature – means that this signature can no longer be verified successfully afterwards.
Create your signature
Only fonts that are already installed on your device are used, so the look can differ from device to device.
Sign on white paper and take the photo straight from above. At most 15 MB.

Sign a PDF without uploading it
A visible signature, not a certificate-based signature
The tool places your signature on the page as an image – just as if you had signed a printout and scanned it again. It does not check who is signing and creates neither a certificate nor a log. That means it is not a qualified or advanced electronic signature.
For forms, delivery notes, acceptance reports or internal approvals, a visible signature is often all you need. If you are unsure which form your document requires, check before you sign.
Three ways to sign
- Draw: with your mouse, finger or stylus – pressure and speed give the line a natural look
- Type: your name in a script font that is already installed on your device
- Image: a photo or scan of your signature, with the white background removed if you like
- Optionally add the date as text, for example below your signature
Good to know
The signature lands exactly where you see it in the preview – also on rotated or cropped pages. With “Add to all pages” you put your initials on every page in one step, at the same distance from the edge.
Your signature is not stored anywhere. As soon as you close the page, it is gone from your browser.

FAQ
Questions about signing PDFs
Is this an electronic signature with a certificate?
No. The tool adds your signature as an image. It does not verify anyone's identity and creates no certificate – it is not a qualified or advanced electronic signature. Signatures with SMS code, audit trail and certificate are available with PaperOffice Sign as a simple electronic signature (SES) under eIDAS.
Are my PDF and my signature uploaded?
No. Everything runs in your browser. Neither the document nor your signature leaves your device, and nothing is stored.
Can I add several signatures or initials?
Yes. You can create several signatures, place each one as often as you like and, for example, put your initials on every page with “Add to all pages”. You can add the date as text, too.
Can I use a photo of my signature?
Yes, as a PNG or JPG. Sign on white paper and take the photo straight from above. If you like, the tool removes the white background so that only the lines appear on the document.
Can I sign password-protected PDFs?
Yes, if you know the password. Enter it right in the file list. The signed file is saved without password protection.
