How to Compress an Image to a Specific KB Size
A specific file-size limit is one of the most common reasons people need an image compressor.
The fastest path is to try target-size compression first, then resize or crop if the original image is too large for the requested KB limit.

Open Compress Image to Exact SizeStart with a realistic target
Targets such as 200KB, 300KB, or 500KB usually preserve usable quality for ordinary photos.
Very small limits such as 20KB or 50KB may require a smaller image dimension before compression can succeed cleanly.
Use quality search, not one fixed setting
A single quality value cannot guarantee a final file size because every image has different detail, colors, and dimensions.
Target compression tests multiple quality levels and keeps the best smaller result it can produce in the browser.
Resize or crop when quality is not enough
If the smallest output is still above the target, the image probably has too many pixels for that size limit.
Crop unused background or resize the image, then run compression again so the final copy stays readable.
