Frequently asked questions
How does it hit a specific size?
It tries quality levels until the file fits under your limit, keeping the highest quality that does. If even low quality is too big, it also reduces the pixel size step by step, and tells you the new dimensions.
Why is my file a little under the limit, not exactly on it?
Image files can’t be cut to an exact byte count, so the tool aims just under your limit. That’s what upload forms need.
Is 1 MB 1000 KB or 1024 KB?
This tool uses 1 MB = 1000 KB, like most upload forms and phones. If a form is strict, set a slightly lower limit (for example 950 KB for “1 MB”).
Can I compress many photos to the same size?
Yes, up to 100 at once. Each one is made to fit your limit.
Are my photos uploaded?
No. Everything happens in your browser, on your device.
