Alignment snaps the signature to the page edge (using your margin) or the page centre, keeping the other direction as-is. One size and position apply to every page — resize once, and all pages resize with it.

After signing, your signed copy (your-file-signed.pdf) appears here, ready to open, download or share. Nothing is uploaded to a server.

📚 Every page, one click

No signing page by page. Pick “All pages” and the same signature is stamped at the same spot on each page.

🎯 Drag to the exact spot

Presets for the usual corners, plus free dragging on the preview when a form needs it somewhere specific.

🔒 Private by design

Signing happens entirely in this browser tab using PDF libraries loaded on the page — your documents stay on your device.
