About this tool

Image Compressor makes JPG, PNG and WebP files smaller so they upload faster, fit email limits and take less space on your phone. You can see how much each image was reduced.

Set the quality and the largest side of the image. A quality of 75% and a largest side of 2000 px is a good starting point for photos. Lower the numbers if you need an even smaller file.

Compression happens in your browser, so your images are never uploaded to a server.

Tips and common problems

For WhatsApp and email, a maximum size of 1280 px is plenty. For websites, 1280 to 2000 px is usual.
WebP is the smallest, but a few old apps cannot open it. Choose JPG when you are not sure.
Do not compress the same picture again and again. Start from the original each time, because every round loses a little detail.
Need an exact width? Use the Image Resizer and then compress the result.
Screenshots with text may look slightly softer after compressing. Use a larger maximum size for them.
