Sign PDF
Draw your signature with the mouse/finger, type it in a script font, or upload a photo of your signature, then drag it onto the exact spot on any page — a quick way to sign a form without printing and rescanning it.
How it works
- Draw, type or upload a signature image.
- Resize and position it precisely before saving.
Private by design
The file never leaves your device — everything runs inside your browser tab using JavaScript PDF libraries, with nothing uploaded to any server. That also means there's no per-day limit on how many files you process, since nothing is metered on a server.
Good to know
A larger PDF is handled a page at a time internally, so it takes a little longer rather than failing outright — closing other heavy browser tabs helps if the device has limited RAM.
Frequently asked questions
Is this a legally-binding e-signature?
It places a visual signature image on the page; for legally certified e-signatures (with an audit trail) you'd need a dedicated e-sign service — this is best for informal forms and drafts.
Is there a sign-up or a watermark?
No — no account needed and the output file carries no watermark.
Does it work on mobile?
Yes, it runs in any modern mobile browser on Android or iPhone, not just on desktop.
Is my file kept or deleted after processing?
Neither — it's never uploaded in the first place, so there's nothing stored on any server to delete.
