Frequently asked questions
What quality should I use?
70–80% is usually indistinguishable from the original and much smaller.
Why is my PNG bigger?
PNG is lossless. Converting photos to WebP or JPG gives far better compression.
Is Compress Image free?
Yes. Compress Image is completely free, with no sign-up, no watermark and no usage limits.
Is my data uploaded to a server?
No. Compress Image runs entirely in your browser. Your files and text never leave your device.
Does it work offline?
Yes. After Red Cat Tools has loaded once, this tool keeps working without an internet connection. You can also install Red Cat Tools as an app.
