Frequently asked questions
How much smaller will my images get?
Phone photos often shrink by 70–90%, especially when you also limit the size to 1920 px. Already-optimized images shrink less.
Why choose WebP?
WebP files are usually 25–35% smaller than JPG at the same quality and work in all modern browsers. PNG screenshots in particular get much smaller as WebP.
Is Compress Image free?
Yes. Compress Image is free to use with no sign-up and no watermark.
Are my files uploaded to your server?
No. All processing happens locally in your browser using JavaScript and WebAssembly. Your files never leave your device, which also makes it fast and private.
Does it work on my phone?
Yes. It works in any modern browser on Windows, Mac, Linux, Android and iPhone. Very large files may be slow on older phones.
