FAQ

Is my file uploaded to a server?

No — everything runs locally in your browser; your file never leaves your device.

What does flattening preserve?

Anything visible — stamps, signatures and filled-in form fields — is drawn permanently into the page so it can no longer be edited or removed. Annotations with no visible content are dropped.
