Will my image be exactly 50 KB?

It will be 50 KB or slightly less, never more. We pick the highest quality that fits, so you get the sharpest image possible within the limit.

How do you get large photos down to 50 KB?

First the compression quality is lowered. If that isn't enough, the pixel dimensions are reduced step by step until the file fits.

What if my image is already under 50 KB?

Then the original is kept unchanged. The tool never makes a file bigger or lowers quality more than needed.

Which format will I get?

JPG, PNG, WebP and AVIF images keep their format. iPhone HEIC photos and other formats become JPG (or PNG if they have transparency). You can also choose the format yourself.

Images travel over an encrypted connection, are processed automatically on our servers and are deleted within an hour. You can delete them immediately after downloading. We never look at or share your images.

How it works

How to use Compress Image to 50KB

The target is preset to 50 KB; change it if you need another size.
3
Click Compress, then download your image or a ZIP of all of them.

Never over the limit

Every image comes out at 50 KB or less, so uploads aren't rejected.

Best quality that fits

We search for the highest quality that still fits, then re-optimize the file with mozjpeg.

Smart resizing

Dimensions are reduced only when lowering the quality isn't enough.
