Why compress an image to 30KB?
Many online forms — job portals, exam and visa applications, government services — only accept photos and scanned documents under a strict size limit such as 30KB. This tool finds the highest quality that still fits under your limit, so your image stays as sharp as possible.
How it works
The tool tries different JPEG quality levels to find the best one under 30KB. If the image is very large, it also reduces the pixel dimensions slightly until it fits. Everything happens in your browser — your image is never uploaded to a server.
Tips for the best result
- Crop away empty space before compressing — fewer pixels means better quality at the same size.
- Photos compress better than screenshots with lots of text.
- If a form asks for exact pixel dimensions too, resize first, then compress.
Frequently asked questions
Is my image uploaded anywhere?
No. The image is processed entirely in your browser and never leaves your device.
What if my image is already smaller than 30KB?
The tool will still re-save it at the highest quality that fits, which usually keeps it under the limit.
Can I choose a different size?
Yes. Change the target size box to any value in KB and the image is compressed again.
