Why PNG → JPG saves so much space
PNG uses lossless compression, great for quality but heavy on disk. JPG's compression algorithm cuts file sizes by 50–80% with barely visible quality loss — perfect for photos and web images.
Background colour matters for transparency
JPG has no transparency layer. Any transparent area must be filled with a solid colour before converting. Use white for documents, black for dark-themed content, or pick a custom colour to match your site.
Quality presets explained
Web (60%) is ideal for fast-loading pages. Balanced (92%) is indistinguishable from lossless at half the size. Max (100%) is JPG's best — still smaller than PNG for photos.
