What Is AVIF and Why Is It the Best Web Image Format?
AVIF (AV1 Image File Format) is a next-generation image format based on the AV1 video codec, developed by the Alliance for Open Media. It represents the current state of the art in image compression. AVIF typically achieves 50% smaller file sizes than PNG and 20% smaller than WebP — at equivalent visual quality — making it the most efficient format available for web image delivery.
AVIF was designed to support modern display capabilities: wide color gamut (HDR), 10-bit and 12-bit color depth, transparency, and high-dynamic-range content. Unlike JPG, AVIF loses no noticeable detail even at aggressive compression ratios. Unlike PNG, AVIF delivers this quality at dramatically smaller file sizes.
Browser support has caught up: Chrome, Firefox, and Safari all support AVIF on modern operating systems. For web projects targeting current browsers, AVIF delivers the best possible combination of visual quality and file size — measurably improving Core Web Vitals, Lighthouse scores, and bandwidth costs.
Converting PNG to AVIF and Related Tools
The converter renders PNG images on an HTML canvas and encodes them as AVIF using the browser's native encoding support. Transparency is preserved. Processing is entirely local — images never leave your browser. No account or payment required.
For images that need to remain in PNG format, the Image Compressor reduces PNG file sizes without format conversion. To convert between AVIF and PNG in the reverse direction, the AVIF to PNG converter is available. For JPG to AVIF conversion, use the JPG to AVIF tool. For legacy compatibility where AVIF may not be supported, PNG to WebP provides the next-best compression ratio.
Frequently Asked Questions
Do all browsers support AVIF?
All major modern browsers support AVIF: Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. Internet Explorer does not. For production web use, providing WebP as a fallback for older browser versions is a safe strategy.
Is transparency preserved in AVIF?
Yes. AVIF supports full alpha transparency. Transparent areas in your PNG will be preserved in the output AVIF file.
How much smaller will the AVIF be than the PNG?
Typically 40–60% smaller for photographic content, sometimes more. For PNG graphics with transparency and sharp edges, savings vary but AVIF consistently outperforms both JPG and WebP in size-to-quality ratio.
Are my images uploaded to a server?
No. Conversion uses the browser's local encoding capabilities. Your images are processed in browser memory and never transmitted externally.
Does this tool work on mobile?
Yes. Chrome on Android and Safari 16+ on iOS both support AVIF encoding. The tool runs in the mobile browser with identical functionality to the desktop experience.
