About this tool
Many application forms ask for a signature image at a specific small size — 50mm x 20mm is a common one. This tool crops your signature scan to that exact wide, short aspect ratio and fills the frame, rather than leaving whitespace around it.
For the cleanest result, sign clearly on plain white paper, photograph it with good lighting, and center the signature roughly in the frame before uploading — the automatic crop is centered on the image, not the ink itself.
Questions
Will this crop off part of my signature?
The crop is centered on the photo frame, not on the ink — make sure your signature is roughly centered in the source photo first.
What background works best?
Plain white or light paper with good, even lighting gives the cleanest result.
Is my signature uploaded anywhere?
No — cropping and resizing happen entirely on your device.
