How to Reduce Image Size from MB to KB Without Losing Quality

Why file size matters

Many online forms accept only images under 100 KB or 200 KB, and smaller images make websites load faster and use less mobile data.

How compression works

Compression removes detail the human eye barely notices. Lowering quality slightly can cut a file by more than half while the picture still looks almost identical.

Steps to compress an image

Open our Image Compressor, choose your photo, move the quality slider until the size meets your limit, and download the result. Your photo stays on your device the whole time.

Tips

If the size is still too big, reduce the image dimensions first, then compress. Save photos as JPG rather than PNG when transparency is not needed.
