How compression works here

Lossy formats (JPEG, WebP, AVIF) discard detail to save bytes. Higher quality keeps more detail and typically larger files.

PNG compression is limited by the format; this tool re-encodes through the browser canvas and may not beat a dedicated PNG optimizer.

Target size uses a quality search and returns the best attempt — exact byte counts cannot be guaranteed.

Will the image look the same?

At high quality the difference is often hard to notice. Lower quality saves more space and can show artifacts.

Can I hit exactly 500 KB?

Not reliably. The tool searches for a quality that lands near your target and shows the best result it found.
