How to use the Compress Image to 500 KB
- Drop one or more photos onto the box — Target file size is already set to 500 KB.
- Pick an output format if you need one (JPEG works everywhere; WebP is smaller).
- Each image is saved at the best quality under 500 KB. Check the before/after view, then download one image or all as a ZIP.
Where 500 KB limits come up
500 KB is a typical limit for CMS and marketplace uploads (product photos, listings) and a sensible maximum for large website images.
How it fits the image under 500 KB
Instead of guessing a quality, the tool tries qualities and keeps the highest one that stays under 500 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
At 500 KB a full-width photo keeps excellent quality. For web pages, also consider WebP — the same image is usually 25–35% smaller.
Need a different size? Change Target file size on the page, or use the image resizer for exact pixel dimensions.
