How to compress an image to 20KB
- Choose or drop your photo above. JPG, PNG, WebP and GIF all work.
- Leave the target at 20KB, or type a different limit.
- Download the result. The new file size is shown next to each image.
How the size limit is reached
The tool tries the highest image quality that still fits under 20KB. If quality alone isn’t enough, it gently reduces the pixel dimensions until the file fits. You always get the best-looking version that meets the limit.
Many exam, scholarship and government application portals ask for a passport-style photo or signature of 20KB or less. This tool gets you there in one step.
Frequently asked questions
Will my photo still look good at 20KB?
For small uses such as profile photos, ID photos and form uploads, yes. A 20KB file works best at smaller dimensions, so the tool reduces the size automatically if needed.
Why did my image come out as JPG?
PNG files can’t be compressed by quality, so reaching a size limit usually requires JPEG. Choose WebP in Output format if you prefer it.
Are my images uploaded to a server?
No. Everything happens inside your browser on your own device. Your images are never sent to Tech9Pros or anyone else, so the tool also works with private photos and documents.
Can I process several images at once?
Yes. Select or drop up to 30 images together. Each one gets its own download button, and you can save them all as a single ZIP file.
