Photograph your signature on white paper. We clean the paper to pure white, crop to the ink and resize it to the exact pixels and file size your application form asks for.

How it works
Paper to white
Shadows and grey paper become pure white, and the ink is kept smooth, so the signature looks clean at small sizes.
Crop to the ink
Empty paper around the signature is removed, with a small margin, so the signature fills the space the form gives it.
Exact pixels and KB
The signature is centred in the exact width and height you set, then compressed to stay under your file limit.
Nothing uploaded
Everything runs in your browser. Your signature never leaves your device.
Questions
How do I resize my signature to 20 KB?
Upload a photo of your signature, choose a size such as 140 × 60 px with 20 KB, and download. The tool compresses the JPG until it fits under 20 KB.
Is cleaning my signature allowed?
Yes. Making the paper white and cropping doesn't change your signature itself. Don't redraw or trace it; use your real handwritten signature.
What pen should I use?
A black or dark blue pen on plain white paper gives the cleanest result. Avoid lined paper.
Is my signature stored?
No. The image is processed in your browser and is not uploaded or stored.
