Image Compressor

Typical savings are 40-80% depending on the original format and quality setting. A 5MB iPhone photo can often be compressed to under 500KB at quality 80% with no visible difference. The tool shows original and compressed sizes in real time so you can find the right balance.

For web use, 75-85% works great. Most people can't tell the difference from the original, and you save a lot on file size. Below 50%, artifacts start showing, especially on gradients and skin tones. For archival, stay above 90%.

WebP is typically 25-34% smaller than JPG at the same quality, and up to 26% smaller than PNG. If you need the absolute smallest file and your platform supports it, choose WebP. JPG is the safest choice for universal compatibility.

No. Width and height stay exactly the same. Compression only changes how the pixel data is encoded. It discards subtle information that the human eye is least likely to notice.
