target 20KB — auto quality searchCompress image to 20KB — how it works
A 20KB limit is extremely tight. It is common for forum avatars, chat application icons, favicons and legacy systems that enforce a hard ceiling on uploaded images. At this size the image must be small in both pixels and quality: a 20KB file usually means a width of around 200-400 pixels for a photo, and even less for a detailed picture.
To reach 20KB the tool lowers quality aggressively and, if needed, you should resize the image down before compressing. Export as JPG or WebP for the best results — PNG is lossless and will struggle to reach 20KB without destroying the colours. For an avatar or icon, a tiny dimension like 128x128 or 256x256 combined with JPG output almost always fits comfortably.
Because 20KB is so restrictive, expect visible quality loss on anything but a very small image. The tool always returns the best-looking result that meets the target.

Frequently asked questions
How do I compress an image to under 20KB?
Drop your image into the tool above. It automatically lowers the quality until the file is 20KB or less. For such a small target you will usually need to resize the image first — something like 256x256 pixels — and export as JPG or WebP.
What size image fits in 20KB?
Roughly 200-400 pixels wide for a photo, less for a detailed graphic. A 128x128 or 256x256 avatar exported as JPG fits 20KB easily at a reasonable quality. Larger images will look heavily compressed.
Is 20KB enough for a photo?
Only for very small displays. 20KB is really meant for avatars, icons and thumbnails. For a full photo you would normally want a larger target like 100KB or 200KB.
Is the 20KB compressor free and private?
Yes. Everything runs entirely in your browser, so your image is never uploaded. It is free with no sign-up, no watermark and no limits.
