Image Compressor
Compress JPG, PNG and WebP images for free. Set quality and max dimensions to shrink file size, process multiple images at once and download them as a ZIP. Images are processed in your browser and never sent to a server.
FAQ
Are my images uploaded to a server?
No. Compression runs entirely in your browser; your images never leave your device.
How much smaller will my images get?
It depends on the original, but photos (JPG) at 75% quality often shrink to about 30–50% of their original size. Setting a max width/height shrinks them further.
Can I compress multiple images at once?
Yes. Select multiple files and you can download all compressed images together as a ZIP file.
Does PNG transparency survive?
Yes if you choose PNG as the output format. With JPG, transparent areas are filled with white.
