Need to compress an image to 20KB? This free online compressor reduces any JPG or PNG to 20KB or smaller in seconds — right in your browser, with no watermark, no sign-up, and no software. Just upload, and the tool automatically finds the right quality (and downscales if needed) to hit your target size while keeping the image as sharp as possible.
Why compress to 20KB?
Many websites and forms enforce a maximum file size, and a photo straight from a phone or camera is usually far too big. Compressing to 20KB is ideal for strict upload limits like government forms, exam applications, and job portals. Instead of guessing at a quality slider, you set the target and the tool does the math — binary-searching the compression level and, for very small targets, gently reducing the dimensions until the file fits under 20KB. It's free and unlimited, so you can compress as many images as you need.

Set the target to 20KB
The target size is preset to 20KB. You can fine-tune it or pick another size — the tool automatically compresses to hit it.
Download the smaller file
Save your compressed image at 20KB or under. No watermark, no quality-wrecking, and no limit on how many you compress.
Frequently asked questions
How do I compress an image to 20KB?
Upload it to JPT AI's free compressor, set the target size to 20KB, and download the result. The tool automatically adjusts quality (and dimensions if needed) to fit under 20KB.
Will compressing to 20KB ruin the quality?
Very small targets like 20KB require heavier compression, so some detail is lost — but the tool keeps the image as sharp as possible for that size, which is usually fine for forms and thumbnails.

Yes — completely free, no sign-up, no watermark, and no limit on how many images you compress.
Does it work on phone?
