Convert any PNG file to AVIF online for free. Upload your PNG and download an AVIF in seconds. Works in Chrome 101+ and Firefox 113+. No signup, no software, no watermarks.
AVIF supports full transparency, making it a direct upgrade from PNG for web use. At the same visual quality, AVIF files are typically 50 to 70 percent smaller than PNG, while still supporting the transparent backgrounds that PNG is used for. Converting PNG UI assets, logos and graphics to AVIF significantly reduces web asset payload.
AVIF output is currently supported in Chrome 101+ and Firefox 113+, which include a built-in AVIF encoder. Safari supports AVIF display but does not include an AVIF encoder.
PNG is the standard for transparent web graphics — AVIF offers the same transparency at dramatically smaller file sizes.
Icons, interface elements and decorative graphics are commonly served as PNG because of their transparency support. AVIF delivers the same transparency in files typically 50 to 70 percent smaller than the equivalent PNG. Converting UI asset libraries to AVIF, with PNG fallbacks for older browsers, reduces the initial page asset weight significantly.
Transparent product photos — product cutouts on white or transparent backgrounds — are often stored as PNG. Converting these to AVIF for web delivery reduces the file size without any loss in the visual quality of the transparent cutout. For product-heavy stores, this conversion directly improves page load performance.
PWA icon sets, splash screens and UI assets distributed to users as part of the app shell can be converted from PNG to AVIF to reduce the total install footprint. Browsers that support AVIF (the vast majority) will load smaller assets, while older browsers receive the PNG fallback.
Quick answers about how this tool works and how to get the best results.
Yes. AVIF fully supports alpha transparency — partial and full transparency, smooth edges and gradients. Converting a PNG with transparency to AVIF preserves all transparent areas correctly. This is the key advantage of AVIF over JPG for graphic assets.
AVIF output requires a built-in encoder included with the browser. Chrome and Firefox include one; Safari currently does not include an AVIF encoder. Open this page in Chrome or Firefox to convert PNG to AVIF.
AVIF produces smaller files than WebP at the same quality but takes slightly longer to encode and decode on older devices. For most modern sites, AVIF with a WebP fallback is the best approach. Use a picture element or CDN-level content negotiation to serve AVIF to supported browsers and WebP to the rest.
Yes. Conversion runs in your browser. Your PNG is never sent to a server. Close the tab and the data is cleared from memory.
