Resize and compress an image to 20 KB
Compress and resize an image to 20 KB in your browser, free. Shows the actual size reached and reports honestly when the target cannot be met.
The resize, compress, and check tools load in your browser. Nothing is uploaded to a server — all processing happens on this device. If you are reading this, the interactive tool is still loading or JavaScript is disabled.
This page starts with a 20 KB target preset so you can compress straight away. A 20 KB limit is small, so it suits simple graphics, icons, and thumbnails better than large detailed photographs. The tool compresses toward 20 KB and shows the actual size it reaches.
If 20 KB cannot be reached for a particular image without reducing it below usable quality, the tool reports that honestly and shows the smallest result it produced. You can switch to a custom target or a larger preset at any time, and your uploaded image is kept while you do.
FAQ
- How do I compress an image to 20 KB?
- Upload your image and run the compressor with the 20 KB target selected. The tool reports the actual output size and tells you if the image cannot be reduced to that target.
- Will a 20 KB image still look clear?
- It depends on the image. Simple graphics can often remain clear at a small size, while detailed photos may lose visible detail. Review the output before using it.
- Can I reduce a JPG photo to 20 KB?
- You can try the 20 KB target with a JPG photo. Detailed photos may need a larger target to retain detail, so review the output and its measured size.
- Does compressing reduce quality?
- Compressing to a smaller file usually reduces quality, because fitting an image into fewer bytes means discarding some detail. The tool aims to keep as much quality as it can while meeting your target, and it always shows the actual size of the result so you can judge the trade-off yourself.
- Are my images uploaded anywhere?
- No. Images are decoded, resized, compressed, and checked inside your own browser. The image bytes, the filename, and the metadata never leave your device, which you can confirm in your browser’s network inspector.
- Is it free?
- Yes. Every tool on this site is free to use, and no account or sign-up is required.
