How to compress an image to 20KB
- Select or drag your photo (JPG, PNG or WebP). You can add several at once.
- The tool automatically tries different quality levels and, only if needed, slightly reduces the dimensions until the file is 20 KB or smaller.
- Click Download. The result is a JPG that is guaranteed to fit the 20 KB limit.
Where is a 20KB limit used?
20 KB is a common upload limit for signature uploads, exam and NTS/PPSC style application forms and small profile pictures. Many people get the error "file size too large" just before a deadline — this page fixes it in seconds without installing any app.
Tips for the best quality under 20KB
- Crop extra empty space first — fewer pixels means better quality at the same size.
- Photos with plain backgrounds compress much better than busy ones.
- If a form also asks for exact pixel dimensions, use our Image Resizer first, then compress here.

Frequently Asked Questions
Will my photo be exactly 20KB?
It will be 20 KB or slightly less — never more — so upload forms will always accept it.
Does it reduce quality?
It keeps the highest quality that still fits under 20 KB. Very large photos may also be scaled down a little.
Why is 20KB so small?
20 KB is used for signatures and thumbnails. The tool lowers quality and dimensions together so text and faces stay readable.
Are my photos uploaded?
