Website loading too slow? Compress JPG, PNG and WebP images online for free — four quality levels, local processing, and results that look identical to the original.
Images are usually 60-80% of a webpage's weight. A 2 MB hero photo might look fine on your screen, but on a phone network it is two seconds of loading before anyone sees anything. Compressing images is the single highest-impact speed fix most sites can make — and it does not require redesigning anything.
Compression reduces file size by removing information your eyes will not notice. For photos (JPG), that means a more efficient encoding of color gradients. For graphics and logos (PNG), it means reducing the number of colors used. A well-compressed image can be 70-90% smaller than the original while looking identical in normal viewing.
As a rule of thumb, a web image should be under 200 KB unless it is a full-screen hero. Compress first, then convert to WebP with the Image to WebP tool for another 25-35% reduction on top — the combination routinely turns a 1.5 MB photo into a 150 KB file with no visible difference.
