500 KB size target
Compress an Image to Under 500 KB
A 500 KB budget is enough to keep documents and scans readable at their original resolution. Drop your file in and the tool lands the sharpest version that fits.

500 KB is a common ceiling on ID uploads, document scans, and recruitment portals. Because we measure the actual bytes instead of applying a fixed quality percentage, the output always lands under 500 KB — never over.
For document work, resolution matters more than compression quality: small text is easier to read at full dimensions than after a downscale. The tool only lowers resolution when every quality setting has already been tried, and it tells you when it does.
Everything runs in your browser. Nothing is uploaded and nothing is stored on our side.

The tool starts pre-filled with the size this page is built for. You can still change it if your form needs something different.

We find the best quality that fits
The compressor re-encodes and measures until it lands just under your target. If quality alone isn't enough, it lowers dimensions as a last resort.
