Signature workflow

Signature Resizer

Resize signatures without clipping the useful part.

Signatures need a different workflow from portraits. This preset uses a wide canvas and contain fitting so the full mark stays visible.

Useful for exam forms, job applications, government uploads, and any workflow with a separate signature field.

Fast answer: Need a signature image that fits form rules? Use the signature-specific route instead of crushing it through a generic photo tool.
