Compress Image to 20 KB

No sign-up. Your photo never leaves your device.

Save as

With a target size, the tool picks the highest quality that fits, and only shrinks the image if even the lowest quality is too big. Target sizes work with JPG and WebP. PNG is lossless, so the quality slider doesn't apply to it. Images are only made smaller, never enlarged. Saving a new copy also drops the photo's EXIF data, such as camera details and location.

Features

Everything you need, nothing you don't

Under 20 KB, automatically

The tool tries quality levels until the file fits, keeping the highest one that does.

Shrinks only if needed

If even the lowest quality is too big, it reduces the pixel size in small steps.

JPG or WebP out

Works with JPG, PNG, WebP and iPhone HEIC photos. WebP usually keeps more detail at the same size.

Everything runs on your device. Nothing is uploaded.

FAQ

Questions about compress image to 20 kb

How do I compress an image to 20 KB?
Add the photo above. With "Under 20 KB" selected, the tool finds the highest JPG or WebP quality that keeps the file under that size, and downloads it.
Will the photo look worse?
Only as much as it has to. 20 KB is very small, so most photos are also reduced in pixel size to fit. If the result is too soft, try WebP, which usually keeps more detail at the same size.
Are my photos uploaded?
No. Compression runs in your browser. Your photos never leave your device.
Can I target an exact size?
The tool aims for the largest file under your target, so results land a little under it. Pick another target from the menu any time.
