Key Features

Draw with Mouse or Touch

Sign with your mouse on desktop or your finger/stylus on tablets and phones. The signature pad captures smooth strokes for a natural-looking handwritten signature.

Place on Any PDF Page

Pick the target page from a thumbnail list and drop the signature where it belongs. Works for last-page contracts, multi-page forms, or initials wherever they're needed.

Adjustable Signature Width

Scale the signature wider for prominent contracts or narrower for compact form fields. Width adjustment keeps the original aspect ratio so handwriting looks natural at any size.

Lossless Overlay

Your signature is added as a vector overlay on the original PDF. Underlying document text and images remain pixel-perfect — only the signed page gains your signature.

Instant — No Account Needed

Sign and download in under a minute. No registration, no email verification, no DocuSign account — just draw, place, and save your signed PDF locally.

100% Private — Signature Stays Local

The signature is captured, rendered, and embedded entirely in your browser. Contracts, NDAs, and HR forms with your signature never get uploaded anywhere.
