memegenPNG to AVIF Converter
Convert PNG images to AVIF right in your browser — free, instant, and private. AVIF is the most efficient mainstream image format, often producing files dramatically smaller than PNG or even WebP at the same quality, and it keeps transparency. Your file never leaves your device.
Updated June 2026
Why convert PNG to AVIF
AVIF (AV1 Image File Format) uses the AV1 video codec's compression to pack images into far fewer bytes than PNG, JPG, or WebP — frequently 30–50% smaller than WebP at a matching quality. Smaller images mean faster page loads and better Core Web Vitals, which is why AVIF has become the go-to format for performance-focused sites.
Like PNG and WebP, AVIF supports an alpha channel, so a PNG with a transparent background stays transparent after conversion. It also handles wide color and high dynamic range, making it a genuine next-generation upgrade.
Browser support and the encoding caveat
Every current browser can display AVIF images. Creating them in-browser is a different story: this tool encodes on the HTML canvas, which today works reliably in Chromium-based browsers (Chrome, Edge, Brave, Opera) but not in Safari or Firefox, which can show AVIF but not export it this way.
If you convert in an unsupported browser the tool detects it and tells you, rather than handing back a mislabeled file. Use Chrome or Edge for AVIF output, or convert to WebP if you need the broadest encoder support.
Choosing a quality level
AVIF holds up at much lower quality settings than JPG or WebP, so the default sits lower on purpose — even 40–60% usually looks clean while producing a tiny file. Raise it toward 90–100% for archival fidelity or images with fine gradients; drop it for the smallest possible files when minor softening is acceptable.
Frequently asked questions
Does this tool upload my PNG anywhere?
No. The conversion runs entirely in your browser on the HTML canvas — your image is never sent to a server. That makes it instant and completely private.
Why does it say my browser can't encode AVIF?
Encoding AVIF on the canvas currently works in Chromium-based browsers (Chrome, Edge, Brave, Opera) but not in Safari or Firefox, which can display AVIF but not export it. Switch to Chrome or Edge to convert, or use our PNG to WebP tool instead.
Does AVIF keep my PNG's transparency?
Yes. AVIF supports an alpha channel, so transparent areas of your PNG stay transparent in the AVIF — just like converting to WebP, and unlike JPG.
How much smaller will the AVIF be?
It depends on the image, but AVIF is typically much smaller than PNG and often 30–50% smaller than WebP at the same visual quality. Photographs and detailed images see the biggest savings.
What quality setting should I use?
AVIF stays clean at low settings, so the default is intentionally low. Around 40–60% looks great for most images while keeping files tiny; raise toward 90–100% for maximum fidelity on gradients or archival copies.
