How it works
The chosen page is rendered to a preview with pdf.js. Your typed or drawn signature is turned into an image, and pdf-lib stamps it onto the page at the position you drag it to — then downloads the signed PDF.
100% client-side — your files are processed in your browser and never uploaded.
Frequently asked questions
Is my document uploaded?
No. The page preview is rendered and the signature is stamped onto the PDF locally with pdf-lib — the file never leaves your browser.
Can I type my signature instead of drawing?
Yes — switch to Type it and your name is rendered in a handwriting style. Or choose Draw it to sign with a mouse or finger.
How do I position it?
A preview of the real page is shown — just drag the signature onto the exact spot, then click Sign PDF.
Is a drawn signature legally valid?
A typed or drawn signature is widely accepted for everyday agreements, but for legally-binding e-signatures with an audit trail, use a qualified e-signature service.
