PDF Sign — what it does
Places your signature on a PDF — draw it with a mouse, finger or stylus, or upload a picture of it — then drag it into position on any page and export the signed file. Everything happens in your browser, so your signature image is never uploaded.
How to use PDF Sign
- Open the PDF you need to sign.
- Draw your signature, or upload an image of it, and clean up the background if you scanned it.
- Drag the signature onto the correct page and line — resize it so it sits naturally on the signature line.
- Add a date or name stamp if the form asks for it in print.
- Export the signed PDF.
Worked example: a supplier agreement with two signature pages
A vendor agreement needs your signature on page 9 and an initial on page 12. Draw the signature once, place it on both pages, add the date, and export — the file goes back to the vendor the same day instead of waiting for a print, sign and scan cycle.
At a glance
| Input | Drawn signature or an uploaded image |
|---|---|
| Placement | Any page, dragged and resized to fit the line |
| Where it runs | On-device — the signature image stays in your browser |
| Important | This is a visible signature, not a certificate-based digital signature |
| Better for legal proof | For Aadhaar eSign or a DSC-token signature, use the government's eSign service and keep those files as the signed originals |
Frequently asked questions
- What is PDF Sign?
- Sign a PDF digitally — draw or upload your signature, place it anywhere on any page and export the signed PDF. Everything stays in your browser.
- Is PDF Sign free to use?
- Yes — PDF Sign is free to use, with no sign-up, no install and no account.
- Does PDF Sign upload or store my data?
- No — PDF Sign runs entirely in your browser, so your text, files and results never leave your device.
- Do I need to install anything to use PDF Sign?
- No — it works in any modern browser (Chrome, Edge, Firefox, Safari) with no downloads, accounts or plugins.
- Is this the same as eSign or a digital signature?
- No. This stamps your handwritten signature onto the page, which is what most internal approvals and vendor documents need. A certificate-based digital signature (Aadhaar eSign, a USB DSC token) proves identity cryptographically and cannot be produced by a browser-only tool — for those, use the official service.
- Will the signature look like a photo of paper?
- If you upload a photo, yes, unless you clean it up — the tool is built for placing an image, not for background removal. Drawing the signature with a stylus or mouse generally looks cleanest on a digital document.
