Compress a photo to 50 KB
A 50 KB limit leaves room for a clear passport-style photo, if the pixel size is sensible. Maru keeps the highest quality that still fits under 50 KB, so you don't throw away detail you're allowed to keep.

03 — Tips
Get a clean result
- Some forms set a minimum as well as a maximum (for example 20–50 KB). Enter both so the file lands inside the range.
- A plain, evenly lit background compresses better than a busy one.
- Keep the original photo; always compress from it, not from an already-compressed copy.

Compress a photo to 50 KB: questions
How do I compress a photo to under 50 KB?
Add it above and press Fix & check. Maru searches for the best JPEG quality under 50 KB and shows the exact final size before you download.
My form says 20 KB to 50 KB. Can Maru do a range?
Yes. Open the rules panel and enter 20 as the minimum and 50 as the maximum.
Does it work on a phone?
Yes. Choose a photo or take one; everything runs in the browser.
