Compress Image Online
Big photos slow down websites, bounce off email limits and get rejected by upload forms. This compressor re-encodes your image with a quality level you choose, optionally caps its dimensions, and shows you the exact before/after file sizes — so the trade-off between size and quality is yours to make, not a black box’s.
Format choice matters: JPG and WebP squeeze photos hardest, WebP usually wins at the same visual quality, and PNG stays lossless (its size lever is dimensions, and the tool says so plainly). Metadata such as camera EXIF and GPS is stripped by re-encoding, which often saves extra kilobytes on phone photos.

Frequently asked questions
What quality setting should I use?
For web photos, 75–85% is the sweet spot: visually near-identical, typically 60–80% smaller. For images that will be printed or edited further, stay at 90%+ or keep the original.
Why doesn’t PNG compress as much as JPG?
PNG is lossless — every pixel is preserved exactly, so there is no quality dial to turn. Its file size only drops when dimensions drop. If you need a small file more than perfect pixels, JPG or WebP will get you much further.
Need a file under an exact limit, like 100 KB?
Use the Compress to Exact KB tool — it searches quality and dimensions automatically and tells you honestly whether the target was reached.
