Reduce a photo below 200 KB: a measured example
Changing a file extension does not make a photo smaller. You need to reduce its actual byte size. In this test, our sample photo produced a JPG below the 200 KB limit. The figures below are measured results for one image, not a promise for every photo.

Read the byte limit and pixel requirements separately
A 200 KB limit describes storage size; 600 × 800 px describes image width and height. Meeting one does not satisfy the other. If a recipient requires exactly 600 × 800 px, this tool’s maximum dimensions alone are not enough. They define a bounding box that preserves proportions, not a crop.
This tool uses 1 KB = 1,000 bytes. A result below 200,000 bytes may still fail other requirements. Check the accepted format, background color and required proportions as well.
We changed only the target for the same photo
The original is a 5,184 × 2,916 px JPG. We selected JPG output and a maximum of 1,600 px for both dimensions, allowing additional reduction when needed. This particular image remained at 1,600 × 900 px for all three targets.
A file for the 500 KB target does not have to be exactly 500 KB. The target is a ceiling, not a size that must be filled. A sufficiently small result is not deliberately enlarged.

These measurements describe one photo in one browser. Different photos or browsers can produce different sizes and quality.
Raw measurement data (JSON)When the size fits but the image looks soft
Inspect small text, face edges or stamps at a useful magnification. A pleasant full-image preview does not prove that tiny characters remain readable. Smaller is not always better. Raise the target within the recipient’s limit or retake the original when necessary.
Keep the original and save the converted copy separately. Verify the measured size and dimensions, then check that the receiving form accepts the file. This tool does not decide whether an application will be accepted.
