Frequently asked questions
How does it reach the exact size?
It tries quality levels until the file fits and keeps the best one. Only if even low quality is too big are the pixel dimensions reduced, as little as needed.
Is 100 KB counted as 100,000 or 102,400 bytes?
Results are at most 100,000 bytes, so they pass upload forms that count it either way.
What if my image is already small enough?
It's kept exactly as it is, without being re-compressed.
Are my files uploaded?
No. Compress Image to KB runs entirely in your browser: your files are processed on your device and never sent to a server.
Is it free?
Yes. It's free, with no sign-up, no watermarks and no daily limits.
Is there a file size limit?
There's no upload limit, because nothing is uploaded. Very large files are limited only by your device's memory.
