Fill & Sign
Draw, type, or upload a signature image and place it on your PDF.
Fill & Sign fills form fields and places a drawn or typed signature image on the page, then saves a normal PDF. The signature is an image placed on the page, not a certificate-based digital signature; flatten afterwards if the recipient must not edit the fields.
Fill & Sign lets you type into forms, add checkmarks, and drop your signature onto a PDF. It works for both interactive and flat printed forms, because the text is placed on top of the page. Fill & Sign is one of UnboundPDF's 53 free browser-based PDF and image tools: it runs on your own device with no upload, no account and no watermark, and reports what it measured on the output.

Questions about Fill & Sign 6
Are my files uploaded to a server?
No. UnboundPDF processes PDFs locally in the browser — documents are not uploaded to a server. We have no backend that receives, stores, or scans your files.
Can I fill a form that is not interactive?
Yes. Text and checkmarks are placed as an overlay, so flat or scanned forms work just as well as ones with real form fields.
How do I add my signature?
Open the signature tool and draw it with your mouse or finger, type your name in a script style, or upload an image, then click to place it.
Do I need to print the form to sign it?
No. Type into the fields and add your signature on screen, then download the completed PDF.
What if the form has no interactive fields?
You can still place text and a signature anywhere on the page, so flat, non-interactive forms work too.
Can I reuse my signature across pages?
Yes. Add your signature once and place it wherever it is needed before you save.

How your files are handled
The work runs on your own device, inside the browser tab — so there is no server to send your document to.
- Nothing is uploaded. We have no backend that receives or stores documents, so we cannot see your files during processing or after.
- Your device does the work. Large documents are handled in stages, pages are rendered as you reach them, and each job is checked against your device before it starts — so a long run takes longer on a phone than on a laptop, nothing is queued behind other people's jobs, and you can stop a run at any point without touching your original file.
- No account and no watermark. The output is a clean file you can use anywhere, with no sign-up and no hourly cap.
