Compare Image Formats
Side-by-side comparisons of the formats you actually need to choose between. File size, transparency, animation, browser support, and which format wins for each use case.
WebP vs PNG
Side-by-side comparison of WebP and PNG — lossless compression ratios, alpha channel support, and where each format wins for the modern web.
WebP vs JPG
Side-by-side comparison of WebP and JPG — file sizes at equivalent quality, transparency, animation, and where each format wins on the modern web.
WebP vs GIF
Animated WebP vs animated GIF — file size, colour depth, transparency, and the cultural ubiquity that keeps GIF alive despite WebP's technical wins.
WebP vs AVIF
WebP and AVIF compared — compression ratios, browser coverage, encoding and decoding speed, and when the marginal AVIF win is worth the cost.
PNG vs JPG
PNG and JPG compared — when lossless transparency beats lossy compression, file size by content type, and the decision framework for each format.
JPG vs AVIF
JPG vs AVIF compared — file size at equivalent quality, browser coverage, encoding cost, and when the modern format is worth the migration.
WebP vs JPEG XL
Compare WebP and JPEG XL — compression, lossless JPEG recompression, and why browser support decides which you can use today.
WebP vs HEIC
Compare WebP and HEIC — photographic compression, browser support, licensing, and why each suits a different stage of the image pipeline.
WebP vs BMP
Side-by-side comparison of WebP and BMP — file size, transparency, and why an uncompressed 1990s bitmap has no place in web delivery next to WebP.
