How to use the Compress Image to 50 KB
- Drop one or more photos onto the box — Target file size is already set to 50 KB.
- Pick an output format if you need one (JPEG works everywhere; WebP is smaller).
- Each image is saved at the best quality under 50 KB. Check the before/after view, then download one image or all as a ZIP.
Where 50 KB limits come up
Many portals limit passport-style photos to 50 KB — visa and ID applications, exam registrations, HR systems and school forms.
How it fits the image under 50 KB
Instead of guessing a quality, the tool tries qualities and keeps the highest one that stays under 50 KB. If even low quality is too big, it reduces the width and height step by step — so text and faces stay as sharp as the limit allows. PNG images are reduced by lowering the number of colors first.
Tips
Crop the photo to the required ratio (often 35×45 mm or square) before compressing. A tight portrait fits 50 KB at good quality.
Need a different size? Change Target file size on the page, or use the image resizer for exact pixel dimensions.
