Description 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. HEIF (High Efficiency Image File Format) is a modern container format for individual images and image sequences. It typically uses the HEVC (High Efficiency Video Coding, also known as H.265) codec for compression, allowing it to store images at a much smaller file size than JPEG while maintaining equal or better visual quality. HEIF supports advanced features like multiple images in a single file, image sequences, transparency, high dynamic range (HDR), depth maps, and rich metadata.
Typical usage
  • 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
  • Storing high-quality photos on smartphones while minimizing storage space
  • Capturing live photos or short bursts with minimal file size increase
  • Archiving images with embedded depth data for portrait mode editing
  • Delivering high-quality visuals in bandwidth-constrained environments
Typical use cases
  • 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.
  • iOS and macOS devices use HEIC by default for camera images to save space while retaining quality
  • Cloud storage providers optimizing bandwidth by storing HEIF instead of JPEG
  • Professional photographers capturing HDR images in a compact file size
  • Social media platforms testing HEIF to reduce upload times without sacrificing quality
Widely supported by
  • 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+)
  • Apple iOS 11 and later
  • macOS High Sierra and later
  • Windows 10 (with HEIF Image Extensions)
  • Android 9 (Pie) and later (device-dependent)
  • Image viewers and editors like Photoshop, GIMP (with plugins), and Preview

Advantages
  • 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.
  • Much smaller file sizes than JPEG for equivalent quality, thanks to HEVC compression.
  • Supports features JPEG cannot, such as HDR, transparency, animations, and multiple images per file.
  • Enables storage of auxiliary data like depth maps for advanced editing features.
  • Suitable for both lossy and lossless image storage.
Disadvantages
  • 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.
  • Not as universally supported as JPEG or PNG, especially on older devices and browsers.
  • Requires more processing power to encode/decode due to HEVC compression.
  • Patent/licensing restrictions on HEVC can limit adoption in open-source projects.
  • Some software still lacks full support for advanced HEIF features.
Max size note File sizes can be extremely small for photos and graphics, but encoding time grows sharply for very high resolutions or complex animations. While HEIF is efficient, very high-resolution or HDR images with multiple embedded sequences can still create large files; decoding them may be intensive for low-power devices.
