About WebP Files

WebP is a modern image format developed by Google that provides superior lossless and lossy compression for web images. WebP supports transparency and animation while offering significantly smaller file sizes compared to traditional formats like JPEG, PNG, and GIF.

Key WebP Features

WebP offers several advantages for web developers and designers looking to optimize their website performance:

Better Compression - WebP lossless images are 26% smaller than PNGs, and WebP lossy images are 25-34% smaller than JPEGs at equivalent visual quality
Alpha Transparency - WebP supports alpha channel transparency with minimal additional file size, unlike PNG
Animation Support - WebP can replace animated GIFs with much smaller file sizes (up to 64% smaller)
High Color Depth - Supports 24-bit RGB color (16.7 million colors) plus 8-bit alpha channel
Metadata Support - Can contain EXIF, XMP, and ICCP metadata like JPEG files
Broad Support - Now supported by all major browsers including Chrome, Firefox, Edge, Safari, and Opera

Technical Details About WebP

WebP lossy compression uses predictive coding to encode an image, similar to the VP8 video codec

WebP lossless compression uses techniques to take advantage of image regularities

WebP is best for photographic content when using lossy compression, achieving smaller file sizes than JPEG

For illustrations and graphics with transparency, WebP lossless compression often outperforms PNG

Animated WebP usually has dramatically smaller file sizes compared to animated GIFs

WebP file structure consists of a RIFF container with 'WEBP' as the FourCC identifier

Maximum dimensions for a WebP image are 16,383 × 16,383 pixels

Browser Compatibility

WebP is now widely supported across most modern browsers:

Chrome - Full support since version 32+ (2014)
Firefox - Full support since version 65+ (2019)
Edge - Full support since version 18+ (2019)
Safari - Support added in version 14+ (2020)
Opera - Full support since version 19+ (2014)
iOS Safari - Support added in iOS 14+ (2020)
Android Browser - Support since Android 4.0+ (2011)

Note: WebP animation support is more limited, with Safari being a notable exception that doesn't support WebP animation.
