Why convert PNG to AVIF?
PNG is a lossless raster format that reproduces every pixel exactly and fully supports transparency. AVIF is a next-generation format built on the AV1 codec, producing the smallest files of any mainstream format at a given quality.
Both PNG and AVIF support transparency, so transparent regions are carried across cleanly. Moving from PNG to AVIF usually shrinks the file significantly, often by half or more, thanks to AVIF's efficient compression — great for websites, email, and saving storage. AVIF is supported across all modern browsers and is one of the best choices for website performance and Core Web Vitals.
Pixohub converts PNG to AVIF entirely inside your browser using the HTML canvas API, so your images are never uploaded to a server. That makes conversion instant, completely private, and free — turn as many PNG files into AVIF as you like. Reach for AVIF whenever you need cutting-edge web delivery where the very smallest file size wins.
PNG vs AVIF: what to expect
PNG is best for logos, icons, screenshots, and any graphic with sharp edges or a transparent background, while AVIF shines for cutting-edge web delivery where the very smallest file size wins. Keep your original PNG if you may later need the source file, and export a AVIF copy for sharing and the web.
