Specification https://www.w3.org/TR/PNG/ https://aomediacodec.github.io/av1-avif/
Description PNG (Portable Network Graphics) is a lossless raster image format designed to improve upon the limitations of the older GIF format. It supports millions of colors, full alpha transparency, and optional interlacing. Because it uses lossless DEFLATE compression, PNG preserves every pixel exactly as stored, making it ideal for graphics that need sharp edges, text clarity, and no degradation over multiple saves. 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 where image clarity is critical
  • Icons and UI elements that require transparent backgrounds
  • Screenshots of applications or websites
  • Digital charts, diagrams, and infographics
  • 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
  • Preserving pixel-perfect quality for logos and branding materials
  • Creating assets for responsive web design where crisp scaling is important
  • Maintaining text sharpness in interface screenshots
  • Storing intermediate design work before final export to other formats
  • 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 modern browsers (Chrome, Firefox, Safari, Edge)
  • Popular design software such as Adobe Photoshop, GIMP, and Affinity Photo
  • Image processing libraries like Sharp, libpng, 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
  • Lossless compression retains exact image quality regardless of edits or re-saves.
  • Supports a full alpha channel for smooth transparency and blending effects.
  • Can store high bit depth images (up to 16 bits per channel), making it suitable for professional work.
  • Universally supported across browsers, operating systems, and image viewers.
  • 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
  • File sizes can be significantly larger than JPEG for photographic images due to lossless compression.
  • Does not inherently support animation without APNG extension.
  • Large high-resolution PNGs can be memory-intensive to decode in browsers or apps.
  • 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 technically supporting very large dimensions, decoding extremely large PNGs can consume high amounts of RAM, potentially leading to performance issues in browsers. File sizes can be extremely small for photos and graphics, but encoding time grows sharply for very high resolutions or complex animations.
