One PDF · it stays on your device
ℹ️ This adds a visual signature image to the page — like signing a printout. It is not a cryptographic / legally-certified digital signature.

PNG or JPG · a near-white background is removed automatically · stays on your device

How to sign a PDF (without uploading it)
Most "sign PDF" websites upload your file to their servers, stamp it there, and send it back — then promise to delete it an hour later. This one is different: it does the whole job on your device, and it checks its own work before handing you the file.
- 1Add your PDF. Drag it onto the box or click to pick. It loads straight into your browser's memory — nothing is sent anywhere.
- 2Create your signature. Draw it with your mouse or finger, or type your name in a signature style.
- 3Place, apply & download. Drag it onto the page, size it, apply — your browser stamps the PDF, verifies it, and downloads it.
Why this is safer. Since the tool never uploads your file, there is no copy of it — or your signature — on any server to be hacked, cached, indexed, or leaked. And because it verifies the result before download, you never get a silently corrupted PDF.

Frequently asked questions
How do I sign a PDF online without uploading the file?
Draw your signature with a finger or mouse, or type it, then drag it onto the right spot on the page and save. Everything happens in your browser. Signed forms usually carry your name, roll number and address, so keeping the file off other people's servers is the whole point.
Is my PDF uploaded to a server?
No. This tool runs 100% in your browser using JavaScript. Your file and signature are handled in your device's memory and stamped locally — nothing is ever sent to any server. It even works offline once the page has loaded.
Is this a legally-certified digital signature?
No. This adds a visual signature image to the page — the same as signing a printout. It is not a cryptographic or certificate-based digital signature.
Can I draw with my finger on a phone?
Yes. The drawing pad works with touch, so you can sign with your finger on a phone or tablet, or with a mouse or trackpad on a computer.
Will signing damage or corrupt my PDF?
No. After stamping, the tool re-opens the file and verifies it's intact and the page count is unchanged, before letting you download. If a check fails, it stops instead of giving you a broken file.
Is it really free?
Yes — completely free, no sign-up, no watermark, no account limits. It's part of AttendFlow's free student tools.
