WEBP vs PNG : Guide complet des formats

WEBP

Lossy+Lossless

Compression

PNG

Lossless

WEBP

Full 8-bit alpha channel — same capability as PNG, with better compression efficiency

Transparence

PNG

Full 8-bit alpha channel — each pixel can be any opacity level from fully transparent (0) to fully opaque (255)

WEBP

Supported — animated WebP stores multiple frames with per-frame timing data, offering vastly better quality and smaller files than animated GIF

Animation

PNG

Not in standard PNG; APNG (Animated PNG) is a non-standard extension with limited, inconsistent support

WEBP

24-bit RGB + 8-bit alpha — 16.7 million colors with full alpha transparency

Profondeur des couleurs

PNG

24-bit RGB (16.7M colors) or 32-bit RGBA (16.7M colors + full alpha); up to 48-bit for professional workflows

WEBP

25–35% smaller than an equivalent-quality JPEG or PNG — typically 30–80 KB for standard web images

Taille du fichier

PNG

100 KB – 10 MB — significantly larger than JPG for photographic content

WEBP

Chrome 23+, Firefox 65+, Edge 18+, Safari 14+, Opera 12+. Not supported in Internet Explorer or Safari prior to iOS/macOS in 2020.
