Frequently asked questions
How do I compress an image to exactly 10 KB?
Drop it in β the 10 KB target is already set β and the tool binary-searches the highest quality that still fits, then hands you the file. No slider guesswork.
Is my image uploaded to a server?
No. Compression runs entirely in your browser; the image never leaves your device.
Which formats can I use?
JPG, PNG and WebP input. Output is JPG (works everywhere) or WebP (smaller).
Where the 10 KB limit shows up
The 10 KB target usually comes from tiny signature and thumb-impression boxes, favicons and small profile icons. Set it above and download a file that lands just under the cap.
What to expect at 10 KB
At 10 KB the tool almost always reduces pixel dimensions as well as quality β a clean, small image beats a full-size one full of blocks. Perfect for line-art signatures on white; hard for detailed photos.
A quick tip
Crop to just the mark or face, and use a plain white background so there is less detail to encode. For other targets, use the image compressor hub.
