Compress Image to 50 KB
A hard 50 KB limit — small avatars, profile photos and strict upload forms. Drop an image in and the tool keeps reducing it until it fits, without sending anything to a server.

How to compress an image to 50 KB
Add your image
Drag it in, browse for it, or paste a screenshot with Ctrl + V. Several files at once is fine.
Set the target
It is already set to 50 KB. Leave it, or type a smaller number if the form is stricter.
Download
Every file shows its before and after size. Save them one by one, or take them all as a single ZIP.
When do you actually need 50 KB?
Fifty kilobytes is aggressive. Most modern photos are 2–5 MB, which is forty to a hundred times larger. Only a few places really demand it:
- Profile pictures on forums, portals and older intranet systems.
- Avatar and thumbnail uploads that get displayed at 100–200 px anyway.
- Government and exam forms with a fixed 50 KB ceiling.
- Email signatures and any place where the image travels inside a message.
Because 50 KB is so small, quality alone rarely gets you there from a 4000 px photo. The tool will start shrinking the pixel dimensions once the quality floor is reached — and that is the right order to do it in: a 600 px image at decent quality looks far better than a 4000 px image crushed to mud.
Better still: resize first if you know the display size. A profile photo never needs to be wider than 400 px, and starting from 400 px makes hitting 50 KB easy at good quality. The Image Resizer does that in one step.
