FAQ
How much smaller will my files get?
It depends on the photo. After processing, you'll see the before and after sizes and the percentage saved.
What format are files saved in?
JPG. If a JPG can't be made any smaller, you get the original file back unchanged.
Is it safe to use Compress Image with my files?
Yes. Your files are never uploaded — they're processed only inside your browser. Every page is served with a policy that blocks outgoing connections (Content-Security-Policy connect-src 'none'), and the counter in the bottom-left shows the data sent: 0 bytes.
Is it free? Do I need an account?
It's completely free, no account needed, and there are no usage limits.
Does it work on my phone?
Yes. It works in mobile browsers on iPhone and Android. For very large files, a computer will be faster.
