How it works

Choose a signature photo, scan or single-page PDF.

Whitespace is cropped and the paper background is cleaned before compression.

The actual generated file is checked to ensure it does not exceed the selected maximum.

Is 10 KB always possible?

Very detailed signatures or PNG output may not fit without unacceptable loss. The tool reports this rather than silently exceeding the limit.

Which format should I choose?

JPG normally works best for strict KB limits.

Are dimensions changed?

When no dimensions are entered, resolution may be reduced only as needed to reach the maximum size.
