How to use this tool

Choose a JPEG, PNG or WebP file, or drag it onto the drop area.
Check the target size (currently 20 KB). It is editable, so change the number or the KB/MB unit if your limit differs.
Press the button. The tool lowers the quality first, then reduces the dimensions step by step if the file is still too large.
Compare the preview and the measured output size with the original, and read any notes or warnings.
Download the new file. If it missed the target, adjust the target slightly or crop the original, and try again.

What to know before you compress Image to 20 KB

Twenty kilobytes is a popular limit because it is small enough to load instantly yet large enough to keep a face clearly recognisable. A JPEG of this size is a modest-sized picture for a portrait, and somewhat larger for simple graphics. If your first attempt is still above 20 KB, the tool scales the picture down gradually instead of jumping straight to a tiny version, which keeps as much resolution as the limit allows. The tricky cases are large camera originals and busy scenes, because they begin so far above the target. For those, cropping before compressing makes a bigger difference than any quality slider.

Twenty kilobytes works for avatars, small icons and compact document photos. If the first pass is still too large, the tool scales the picture down step by step. The size you enter is a goal, not a promise: the result depends on the original image, its dimensions, its complexity, its format and your browser's encoder, and the tool reports the real size instead of assuming it.

Recommended settings and supported formats

Leave the output as the original format for JPEG files. For PNG, consider switching to JPEG or WebP, since PNG can only shrink by removing pixels. The 20 KB default is editable, so you can raise it if the form permits something slightly larger.

Accepted input: JPEG, PNG and WebP (WebP depends on your browser). HEIC and AVIF are not supported. PNG is lossless, so it can only get smaller with fewer pixels unless you choose JPEG or WebP output.

Practical uses

Avatar and profile photo uploads with a small limit
Compact photos for application and registration forms
Icons and small illustrations for lightweight pages

Tips for a smaller file

Crop before compressing to focus the pixel budget.
Plain backgrounds compress better than patterned ones.
Prefer JPEG output for photos and PNG only for flat graphics.
Check the preview at the size it will actually be displayed.

Frequently asked questions

How do I compress an image to 20 KB?

Choose your file, keep the target at 20 KB, and select Compress. The tool lowers the quality, scales the dimensions if needed, and shows the measured result for you to download.

Why did my image end up bigger than 20 KB?

Large or highly detailed images may not reach the target within the number of attempts the tool makes. Crop the picture or raise the target a little and try again.

Does compressing to 20 KB change the file format?

Not unless you choose to. JPEG, PNG and WebP files keep their format by default, and you can switch the output to JPEG or WebP if that helps.
