Signature Resizer

Bank forms, exam applications, and government portals often reject a signature for being the wrong pixel size or too large a file. Fix both at once.

Getting a clean signature scan

Sign your name in dark ink on plain white paper, then photograph or scan it under even light with no shadow across the page. Crop reasonably close to the signature before uploading — the tool will handle the exact final framing.

If the form specifies a maximum file size (common on exam and banking portals), use the target file size field — the tool will find the highest quality that still fits under that limit.

Frequently asked questions

Why do forms specify both pixel size and file size for a signature?

Pixel size controls how the signature displays and prints; file size (in KB) limits how much data the form's upload system will accept. This tool controls both at once.

What if my form gives a size not in the presets?

Choose Custom size and enter the exact width and height with the unit the form specifies (px, mm, cm, or inches).
