When is a 20KB target useful?
A 20KB ceiling is useful when a form, content field, or service asks for a very small image. It can suit compact avatars, icons, thumbnails, and simple graphics where a little loss of detail is acceptable. It is usually a demanding target for a detailed photograph or a large screenshot, so preview the result at the size where it will be used.
This page starts the target-size mode at 20KB. The compressor searches for a high-quality result below that target by trying suitable quality and, when useful, size adjustments. It does not promise that every image can reach 20KB without a visible trade-off. Source content, dimensions, and output format all affect the final result.
Supported formats and privacy
Choose from supported inputs and export to JPEG, PNG, WebP, or AVIF where the workflow supports it. For this compressor, image files are processed in the browser rather than sent to a compression server. Use the format-specific JPEG compressor, PNG compressor, WebP compressor, or AVIF compressor when you want to start with a particular output format.
Other size and use-case tools
If 20KB is too small for the image, try the general compressor or the 100KB compressor. For several images at once, use the bulk image compressor. The email compressor and Discord compressor are more useful when your destination has a different workflow.
All image tools
Compress, resize, crop, convert, and more — all in your browser.

Frequently asked questions
-
How do I compress an image to under 20KB?
Upload your image to the compressor. The target is preset to 20 KB, and the compressor searches for a high-quality result under that target. The final quality and exact size depend on the source image, its dimensions, and the output format.
-
Can every image be compressed to 20KB?
Not without a trade-off. A very detailed photo, a large screenshot, or an image with transparency may need to be resized or changed to a more suitable format to reach 20 KB. Preview the result before downloading.
-
Which image formats can I use?
The compressor accepts common image inputs and can output JPEG, PNG, WebP, or AVIF. JPEG and WebP are often practical for small photographic files, while PNG is useful when transparency or sharp edges matter. Availability and results depend on the source image.
-
Are my images uploaded?
For this compressor, image files are processed in the browser. They are not uploaded to a server for compression, so keep the page open until processing and downloading are complete.
-
What should I do if the 20KB result looks too soft?
Try a larger target with the general compressor, or use the 50KB, 100KB, or 200KB target page when your recipient allows a larger file. You can also keep the original dimensions if small text or fine detail is important.
