Compress Image to Exact KB

Privacy Level 1 — 100% local: your files never leave your browser

Target size

Compress to at most KB

Output format:

Keep original pixel size Only lower the quality, never shrink the image. Some portals also check dimensions — use this when yours does.

How it works: the tool tries the best quality first, then steps down until the file fits your limit. If quality alone is not enough, it shrinks the image a little at a time — and it always shows you the real final size, so a “201 KB” surprise never happens.

Frequently asked questions

Is my photo uploaded to your servers?

No. Your photo is compressed entirely inside your browser. It never leaves your device — you can verify this in your browser's network panel, or disconnect from the internet after the page loads and keep compressing.

How is this different from a normal image compressor?

A normal compressor gives you a quality slider and you have to guess — and a file that comes out at 201 KB is still rejected by a 200 KB limit. Here you type the limit first, and the tool keeps adjusting quality (and, if needed, size) until the file is guaranteed at or under it, then shows you the real final size.

Why does the tool sometimes shrink my photo?

When even the lowest quality is still too big for your target, the only remaining lever is fewer pixels. This happens mostly with very small targets (like a 10–20 KB signature) or very detailed photos. Tick “Keep original pixel size” if your portal also checks dimensions — but note that some very small targets then cannot be reached.

What sizes do visa, exam and job portals usually ask for?

Common limits are 20 KB for signatures, 50 KB for small photos, and 100–200 KB for passport photos on visa, exam (NEET, SSC, UPSC) and government job portals. Always check your own form — the limit is printed next to the upload box.
