Compress an image to a target file size

How to compress to target size

2. Enter the target size in kilobytes.
3. Click Compress to target. The tool tries qualities and reports what it found.
4. Download the result, or read the note if the target was not reachable.

Why this image tool is private

The search runs entirely in memory, re-encoding the image repeatedly until it fits. No copy is ever sent anywhere; the search is your own processor doing the work.

Other tools in this category upload your file to a server, process it in the cloud, and return a download link. That means your document sits on someone else's disk — often with a retention window measured in hours. Here, the file is read by your browser, transformed in memory, and saved straight back to your disk. You can watch it happen in the live check above: the counter for files uploaded stays at zero.
