How this tool works
What it does
Compresses an image toward 20 KB by trying browser-supported encoder settings and, if needed, reducing dimensions, then reports the achieved size. It keeps the largest result at or under 20 KB when it can, otherwise the closest and marks it over target.
Format and transparency
Keeps JPG, PNG, or WebP where possible and converts HEIC, TIFF, SVG, and GIF to JPG. JPG fills transparent areas with your chosen background color.
Privacy
The image is processed on your device to reach 20 KB. Nothing is uploaded, and re-encoding strips EXIF and GPS metadata. Your files are never sent to imgtoolsbase or any other server.
Compress Image to 20 KB in your browser

It reports the size actually achieved. If 20 KB cannot be reached at the current dimensions, the panel shows the closest size and flags it as over target, so you can resize and try again.

Frequently asked questions
Will my image be exactly 20 KB?
No. The tool compresses toward 20 KB and reports the size it actually reaches. It keeps the largest result at or under 20 KB when it can, and tells you if the smallest it can reach is still over.
What if 20 KB is too small for my image?
Very small targets like 20 KB are hard for detailed photos. Lower the dimensions, or accept the closest size the panel reports as the smallest practical result.
Are my files uploaded when compressing to 20 KB?
No. Compression to 20 KB runs in your browser, so the file never leaves your device.
Does compressing to 20 KB change my image format?
When producing a 20 KB file it keeps JPG, PNG, or WebP where it can; HEIC, TIFF, SVG, and GIF are saved as JPG, and animated GIFs become a single still frame. JPG has no transparency, so transparent areas use the background color you pick.
Is EXIF and GPS data removed when compressing to 20 KB?
If the tool re-encodes the image to reach 20 KB, it strips embedded metadata such as EXIF and GPS, which the panel notes. If the original is kept because it is already under 20 KB, its metadata is unchanged.
