What is Image Compressor?
Image Compressor shrinks image file sizes by re-encoding them at a quality level you choose, keeping the original format. Add one image or a whole batch, set the quality, and see the exact size saved on each. It runs in your browser, so nothing is uploaded.
How Image Compressor works
How to compress images
- Add your JPG, PNG or WebP images (single or bulk).
- Move the quality slider — lower means smaller files.
- Download each compressed image, or all of them as a ZIP.
Photos compress best as JPG/WebP. PNG is lossless, so for big savings on photo-like PNGs, convert them to WebP.
Common uses
- Shrink photos for faster websites
