asantoolCompress an image to 50 KB
Bring a photo under 50 KB without leaving the page. By far the most-searched size limit of all, driven by government exam and recruitment forms that demand a photo under 50 KB and a signature under 20 KB. The tool below opens already set to that limit — add your image and it finds the best quality that fits.

Common questions
The form also caps the dimensions. Does this handle that?
Not yet — this tool changes file size, not pixel dimensions. If the form specifies both, crop the photo to the required shape in the image editor first, then compress it here.
How do I compress an image to 50 KB?
Add your image to the tool on this page. It is already set to a 50 KB target, so it will search for the highest quality that lands under that size and show you the result next to the original. Then download it.
Is my image uploaded anywhere?
No. The work happens in your browser using image APIs it already ships with, so the file never leaves your device. There is no upload to wait for and nothing stored on a server afterwards.
