What to expect

Repair is best effort. Editing adds text overlays. Signing requires a PKCS#12 certificate.

Do my files leave my device?

No. File processing runs locally in your browser worker. OneKit does not receive your input files or results. Required public processing libraries may download when you first use the tool.
