When Do You Need Exactly 500KB?
500KB is the high-quality end of web image optimization. It is large enough to retain sharp detail for product zoom, print previews, and full-width hero images — while still loading significantly faster than uncompressed originals of 3–8MB. At 500KB, most web users on 4G or faster connections see instant load times with no visible quality compromise.

Frequently Asked Questions
How do I compress an image to exactly 500KB?
Switch to Exact KB Mode, type 500, choose WebP or JPEG, and click Compress. Binary search finds the maximum quality that fits 500KB — within 1KB accuracy.
Is 500KB enough quality for product photos?
Yes — for most ecommerce use. At 2000px wide and 500KB, WebP retains all the detail buyers need for zoom. Only very high-end fashion or print use cases need larger files.
Is WebP or JPEG better at 500KB?
WebP is clearly better at 500KB — sharper, cleaner, with fewer artifacts. Use JPEG only when the platform requires it, such as Amazon product listings.
Can I compress multiple images to 500KB at once?
Yes — upload up to 50 images, set Exact KB Mode to 500, compress all at once. Download individually or as a ZIP.
