Convert a PNG image to AVIF, the most efficient mainstream image format on the web today. AVIF files are typically 50% smaller than JPG and 30% smaller than WEBP at equal quality, with full transparency support.
PNG to AVIF is the most aggressive image size reduction we offer. AVIF, built on the AV1 codec, routinely beats both PNG and WEBP — often halving WEBP’s size — while preserving transparency and handling gradients without banding. It is ideal for squeezing every kilobyte out of a modern, performance-obsessed site.
Use it when your audience is on current browsers (Chrome, Edge, Firefox and recent Safari all decode AVIF) and raw speed matters more than maximum reach. Encoding takes a little longer than WEBP and very old clients will not display it, so keep a fallback if you must support legacy browsers.
PNG is a lossless image format with full alpha transparency. It is the default for screenshots, logos, UI mockups, and anything with sharp edges or text. PNG files are much larger than JPG for the same photo content — use PNG for graphics and transparent overlays, JPG for photographs.
AVIF is built on the AV1 video codec and delivers the best image compression on the public web today — roughly 50% smaller than JPG at the same quality. All current browsers support AVIF, but Photoshop, WhatsApp, and many email clients do not. Use AVIF for web delivery, then keep a JPG or PNG copy for sharing.
Drop a PNG file from your device, or paste a public URL pointing to the PNG you want to convert.
The output is pre-set to AVIF.
Click Convert. Our cloud workers fetch the PNG, scan it for malware (video and audio over 1 GB are not scanned), and run the PNG → AVIF pipeline.
A download link appears as soon as the AVIF is ready; it works for anyone who has it until the file is deleted. The file is deleted from our storage two hours after it was made (longer for very large files or with a pass), normally within the next 15 minutes.
