How to compress images online — without losing quality

Image compression reduces file size by removing redundant or imperceptible data. Lossy compression (JPEG, WebP, AVIF) discards some image data to achieve significant size reduction, while lossless compression (PNG) reorganizes data without any quality loss.

For web images, a quality setting of 75–85% typically produces results visually indistinguishable from the original while cutting file size by 50–70%. For images that will be printed or edited, use quality 90+.

Converting to WebP can reduce JPEG file sizes by 25–35% at the same visual quality. AVIF goes even further — typically 40–50% smaller than JPEG — and is now supported by all major browsers.
