About the Compress Image to 30 KB
A 30 KB limit shows up on exam application forms, school and college admission portals, and some state government services that want a small passport-size photo.
Upload forms check the file size, not how the picture looks, so a photo that is 2 MB from your phone is rejected even if it looks fine. This tool measures the real file as it compresses: it tries the highest JPEG quality first, lowers it step by step until the file is under 30 KB, and makes the image smaller only if quality alone is not enough. Passport-size photos at 30 KB keep good detail around 300–400 px wide. Use the Passport Photo tool first if the form also needs an exact shape.

- 3
Check the result next to each image: its final size, quality and dimensions.
- 4
Download the image, or all images as a ZIP if you added several.

Examples
30 KBat most 30,000 bytesGood to know
- PNG files are saved as JPG in target mode, since PNG has no quality setting to lower. Transparent areas become white.
- If an image cannot reach 30 KB even at a very small size, the smallest version is offered and clearly marked as still too big.
- Some forms also need exact pixel dimensions. Use Resize Image or Passport Photo Maker first, then compress.
Frequently asked questions
Why does my 30 KB photo look softer than the original?
To fit 30 KB, the tool lowers the JPEG quality and, if needed, the pixel size. Faces stay clear at this size, but fine background detail is lost. A plain background helps, since it compresses much better.
How do I get exactly 30 KB?
Forms ask for a maximum, so the tool keeps the file at or just under 30 KB at the highest quality that fits. It never goes over the limit.
Does it work on my phone?
Yes. Choose a photo from your gallery or take one with the camera. Everything runs in the phone's browser, so it also works on a slow connection once the page has loaded.
Are my files uploaded?
No. Files are opened and processed in your browser, in a background thread. Nothing is uploaded, so the tool also works for confidential documents.
