How to compress an image to 500 KB
Drop your photo above and the tool is already set to a 500 KB target. It exports as JPEG and automatically searches for the highest quality that still fits under 500 KB, shrinking the dimensions only if it has to. Each result shows its final size, so you can confirm it is under 500 KB.
Small file, good quality
Reaching a size limit for an email attachment, a web form or an upload box is the most common reason to compress to 500 KB. Because the tool tunes quality intelligently instead of just slashing it, your photo stays as sharp as possible at that size - and it all happens privately in your browser.
