About the Signature Resizer
A signature is often a small, high-contrast image, so legibility matters more than aggressively reducing bytes. This tool keeps dimensions fixed by default and adjusts JPEG quality within a bounded range. It does not verify SSC, bank or other portal rules: copy the dimensions and limits from your actual application. Do not force a tiny file if the strokes become unreadable.
