What is this tool?

Resize Image to 20KB targets the strictest upload limits found on exam registrations, government portals and legacy systems — 20 kilobytes leaves room for only a small, efficiently compressed image, so the tool automatically balances dimensions and quality to squeeze the most out of the budget. Everything runs locally in your browser.

Common uses

  • Exam and university application portals with 20 KB photo limits
  • Signature images that must stay tiny
  • Government forms from systems with very strict caps
  • Thumbnails and avatars for bandwidth-critical pages

FAQ

How good can an image look at 20 KB?

20 KB is enough for a clear photo at roughly 300–500 px — fine for ID-style photos and signatures. Expect visible softness on anything larger or highly detailed.

Is my image uploaded anywhere?

No. Compression runs entirely in your browser — the image never leaves your device.

The portal wants exactly between 10 and 20 KB — will this fit?

The tool aims just under 20 KB, which satisfies the common '10–20 KB' requirements. If a result lands lower than a required minimum, start from a larger, more detailed source image.
