Compress a photo to 20 KB
Small upload limits like 20 KB are common on exam and job application forms. Squeezing a phone photo that small usually needs two things at once: fewer pixels and stronger JPEG compression. Maru does both, keeps the face sharp, and stops as soon as the file fits.

03 — Tips
Get a clean result
- Crop tightly first. Fewer background pixels leave more of the 20 KB for your face.
- If your form also sets a pixel size, type it into Width and Height below; Maru will fit both rules together.
- If the result looks blocky, the form's pixel size may be larger than 20 KB can hold. Check the form's instructions.
04 — Questions
Compress a photo to 20 KB: questions
How do I reduce a photo to 20 KB?
Add the photo above and press Fix & check. Maru lowers the JPEG quality step by step, and only shrinks the pixel size if it must, until the file is 20 KB or less.
Will compressing to 20 KB make my photo blurry?
It softens fine detail, but faces stay clear at typical form sizes. Cropping tightly before compressing helps most.
Is my photo uploaded anywhere?
No. The compression runs inside your browser and the file never leaves your device.
