Shrink an image to a target file size
A portal asked for 200 KB. Here is how to get close without guessing the quality slider.
A form that says “maximum 200 KB” is asking for a file size, not a vibe. Resaving in a photo app until it “looks smaller” is how people miss the limit by 40 KB and upload three times.
Set the target first
Open Compress image to a size. Pick 200 KB, 500 KB, or 1 MB, or type the number the portal printed. The result panel should show four facts: original size, result size, percent saved, and the target. If the result is still over the target, it says so. That is more useful than a quality percentage with no file size.
When the picture falls apart
Heavy compression on a sharp logo or a screenshot looks worse than the same reduction on a photo. If you need a logo to stay crisp, convert it to PNG with Convert image format instead of chasing a tiny JPG. If the portal also wants exact pixels, resize first with Resize and crop, then compress the export.
- Photos of people and places: JPG toward the stated KB.
- Screenshots of an interface: PNG or a light WebP, unless the form forbids it.
- Several files: compress the batch, then check each result size, not only the first.
Compression runs in the browser. The original file is not uploaded.
