Pro Tips for Compress Image
Get the most out of your compress image experience
Websites
Limit width to 1600–2000 px for hero images and use WebP for the best balance of quality and size.
PNG
PNG is lossless, so the quality slider has little effect. Convert to WebP or JPG for big savings on photos.
Metadata
EXIF data (camera, GPS) is removed during compression, which also helps privacy.

Frequently Asked Questions — Compress Image
Everything you need to know about how to compress image online
Does compression remove EXIF/GPS data?
Yes. The image is re-encoded from pixels, so camera and location metadata are not carried over.
Why doesn't my PNG shrink?
PNG is lossless. Reduce the dimensions or convert to WebP for a meaningful reduction.
Are my files secure while I compress images?
Yes. Everything happens inside your browser using JavaScript and WebAssembly. Your file is never uploaded, and nothing is stored on a server.
Do you keep a copy of my document?
No. The file lives in your browser's memory only. When you close or refresh the tab it is gone. We cannot see it, and neither can anyone else.
