How to use & compatibility

Insert a signature into a PDF. Draw a signature directly with your mouse or finger, or upload a prepared signature image (a transparent PNG is recommended), and place it exactly where you want on any page. It's useful for signing contracts, consent forms, and other paperwork and sending them back without printing, signing, and scanning. Click a position in the preview on the right, adjust the size, and insert it to save a new PDF. Files are processed only in your browser.

Frequently asked questions
Is it legally binding?
It inserts a signature as an image and differs from a certificate-based accredited electronic signature under Korean law. It's suitable for general consent and confirmation.
Can I sign in several places?
One position is inserted at a time; save, then reopen the file to add another in a different spot.
Is my signature stored on a server?
No. Both the signature and the PDF are processed only in your browser.
