Convert PNG images to AVIF — the modern format with 50% better compression than WebP. Supports quality slider (0–100), lossless mode, transparency preservation, and browser support detection. Batch convert up to 10 files.
The tool automatically checks if your browser supports AVIF encoding (Chrome 94+, Firefox 113+, Safari 16.4+). Upload up to 10 PNG files — drag and drop or click to browse.
Use the quality slider (0–100) to balance file size vs image quality. Quality 80 is recommended for photos. Use quality 100 for lossless conversion (larger files). AVIF at quality 60 often looks better than WebP at quality 80.
Click Convert to process all files. Each shows the original PNG size vs output AVIF size and percentage savings. Download individually or as ZIP.
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It provides 50% better compression than WebP and 70% better than JPEG at comparable quality. AVIF supports HDR colours, 12-bit depth, transparency, and animation. It is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. AVIF is particularly efficient for photographs and real-world images.
Yes. AVIF supports full alpha channel transparency, making it suitable for replacing both PNG (for graphics with transparency) and JPG (for photographs). The Canvas API preserves transparency when encoding to AVIF.
AVIF encoding support via the Canvas toDataURL API requires a relatively recent browser: Chrome 94+, Edge 94+, Firefox 113+, or Safari 16.4+. Older browsers can display AVIF images (support was added earlier) but cannot encode them. If encoding is unavailable, the tool shows a warning and suggests converting in Chrome or Edge.
AVIF: best overall for photos and complex images on modern browsers — smallest files. WebP: excellent compatibility (all modern browsers), good compression — the safe default for web. PNG: use only when lossless compression with transparency is required for graphics, logos, and UI elements where WebP or AVIF quality is unacceptable. For browser compatibility, consider serving AVIF with a WebP fallback using the HTML <picture> element.
AVIF typically produces files 50–70% smaller than equivalent PNG files at visually similar quality. Lossless AVIF is also 10–20% smaller than lossless WebP. For photographs, AVIF quality 60 often matches JPEG quality 80 visually while being 40% smaller. Results vary by image content — images with solid colours and flat areas compress especially well.
Yes, with a fallback. Use the HTML picture element: <picture><source type="image/avif" srcset="image.avif"><source type="image/webp" srcset="image.webp"><img src="image.jpg" alt="..."></picture>. This serves AVIF to supported browsers, WebP to others, and JPG to legacy browsers. Browser support for AVIF is now over 90% globally as of 2025.
