Description WebP is a modern image format developed by Google that provides superior compression compared to traditional formats like JPEG and PNG. It supports both lossy and lossless compression, alpha transparency, and animation in a single format. This versatility makes it particularly valuable for the web, where reducing file sizes without sacrificing visual quality directly improves page load speeds and user experience. AVIF (AV1 Image File Format) is a modern image format that uses the AV1 video codec for compression, packaged within the HEIF container. It offers exceptional compression efficiency, producing significantly smaller files than JPEG or PNG at equivalent visual quality, and supports advanced features like HDR, wide color gamut, alpha transparency, and both lossy and lossless modes. AVIF is designed for the web and mobile era, reducing bandwidth usage while maintaining visual fidelity.
Typical usage
  • Web graphics and photos where smaller file sizes improve page performance
  • Images that require transparency with minimal size impact
  • Replacing both JPEG and PNG assets with a single format for efficiency
  • Animated images as a more efficient alternative to GIF
  • Web images optimized for speed and low bandwidth usage
  • High-quality photography with smaller file sizes than JPEG
  • Graphics and UI elements with alpha transparency
  • HDR images for next-generation displays
Typical use cases
  • Optimizing e-commerce product images to load quickly without quality loss
  • Serving responsive images for high-DPI (Retina) displays while keeping bandwidth low
  • Replacing animated GIFs with smaller, smoother WebP animations
  • Reducing storage and CDN bandwidth costs for large image libraries
  • Replacing JPEG for high-resolution product photos in e-commerce sites to improve load times.
  • Serving responsive images in web apps with smaller bandwidth costs.
  • Distributing HDR wallpapers and artwork that retain detail and dynamic range.
  • Reducing storage costs for large-scale image hosting platforms.
Widely supported by
  • All major browsers (Chrome, Firefox, Edge, Safari 14+)
  • Design tools like Photoshop (with plugin), GIMP, and Affinity Photo
  • Image processing libraries including libwebp, Sharp, and ImageMagick
  • Modern browsers (Chrome, Firefox, Safari with some limitations, Edge)
  • Image processing tools like libavif, ImageMagick (with AVIF support compiled)
  • Operating systems with native support (Android 12+, macOS Ventura+, Windows 10 21H2+)

Advantages
  • Significantly smaller file sizes than JPEG or PNG at equivalent visual quality.
  • Supports both lossy and lossless compression modes in one format.
  • Full alpha channel support for transparency in both compression modes.
  • Animation support makes it a superior alternative to GIF for quality and file size.
  • Broad browser and tool support has grown, making it viable for production web use.
  • Achieves much smaller file sizes than JPEG, PNG, or even WebP at similar or higher visual quality.
  • Supports HDR (High Dynamic Range), wide color gamut, and deep bit depths (10–12 bits).
  • Offers both lossy and lossless compression in the same format.
  • Supports transparency, making it a viable PNG/WebP replacement in many workflows.
  • Can store animations efficiently with better compression than GIF or WebP.
Disadvantages
  • Older browsers and some legacy devices lack native WebP support, requiring fallback formats.
  • Encoding complexity can be higher, making compression slower for very large images.
  • Not ideal for archival purposes since some software ecosystems still favor traditional formats.
  • Encoding is significantly slower than JPEG or WebP due to the complexity of AV1 compression.
  • Browser and software support, while growing, is not yet universal, which can require fallbacks.
  • Not all tools fully support advanced features like HDR metadata or animation.
  • Older devices and OS versions may be unable to display AVIF without updates or additional libraries.
Max size note While WebP reduces average image sizes significantly, excessively large images can still lead to high memory usage during decoding, especially with animations. File sizes can be extremely small for photos and graphics, but encoding time grows sharply for very high resolutions or complex animations.
