Compress Image to a Target Size
Set a size in KB and get the best quality that fits — free, in your browser, never uploaded.
Frequently asked questions
How does compressing to an exact size work?
Add your image, type a target in KB and it compresses automatically. The tool binary-searches the JPEG quality for the largest value that still fits under the target; if even the lowest sensible quality is too big, it scales the dimensions down step by step until it fits.
Will the photo still look good?
The tool always picks the HIGHEST quality that fits your target, so you never lose more than the size limit forces. Tight targets (like 20 KB) on large photos will visibly compress — that's the trade-off the form's limit imposes, not a flaw of the tool.
Are my files uploaded to a server?
No — compression runs entirely in your browser. That matters here more than anywhere: these images are usually IDs, signatures and application photos.
Which formats can I use?
JPG, PNG and WebP input. Output is JPG by default (accepted by virtually every form) or WebP if the site accepts it — WebP fits noticeably more quality into the same kilobytes.
Is it really free?
Yes — free, unlimited, no signup and no watermark.
