Sign PDF online — no app, no account
Signing a PDF online doesn't have to mean uploading sensitive documents to a third party. Krymp signs locally: open the page, drop the PDF, sign with finger/mouse or type, save. The signed file is built in your browser using pdf-lib — nothing reaches a server.

Vanliga frågor
Do I need to install software?
No — it runs in your browser.
Account?
Not required.
Is the signed PDF editable later?
The signature is flattened into the page, so it can't be moved or removed without re-editing the PDF.
Mobile?
Yes — draw with your finger.
Privacy?
All local — your PDF stays on your device.
