Frequently asked questions

Does AVIF keep the transparency from my PNG?

Yes. AVIF fully supports an alpha channel, so transparent backgrounds are preserved exactly while the file shrinks dramatically. That makes it a strong replacement for PNG on the web when you need both a see-through background and a small download — logos, product cut-outs and UI overlays all keep their edges clean.

How much smaller is AVIF than the original PNG?

Often dramatically — a photographic PNG can drop by 70–90%, because PNG stores everything losslessly while AVIF compresses far more aggressively. Flat graphics and simple icons save less, since PNG is already efficient at those. The busier and more photo-like the image, the bigger the AVIF saving.

Does converting a lossless PNG to AVIF reduce quality?

By default AVIF uses lossy compression, so there is a tiny quality trade for the big size saving — invisible in practice at high quality for photos. If you must preserve every pixel exactly, such as a master graphic, keep the PNG or use a lossless AVIF setting, which is smaller than PNG but larger than lossy AVIF.

Is AVIF worth it for graphics and screenshots, not just photos?

Yes for size, though the saving is smaller for flat graphics than for photos. For screenshots and logos with very sharp edges, PNG sometimes still wins on crispness, since lossy compression can soften hard lines. Test one image both ways if edge sharpness is critical to your design.

Do all browsers support AVIF the way they support PNG?

Not quite yet. AVIF works in all current Chrome, Firefox, Edge and Safari 16+ versions, but PNG has near-universal support including very old software. For maximum reach on the web, serve AVIF with a PNG fallback via the <picture> element so unsupported clients still see the image.

Can I convert a batch of PNG files to AVIF at once?

Yes. Add a whole set of PNGs together and they convert in one pass with no file-count limit — the quick way to modernise an entire folder of web images or an icon set, cutting total page weight without exporting each file individually.

Should I replace the PNGs on my website with AVIF?

For large photographic PNGs, yes — the bandwidth saving is substantial and speeds up your pages. For tiny icons and simple flat graphics the gain is small and may not be worth the extra format. A common approach is to convert the heavy images to AVIF and leave small UI assets as PNG.
