Is AVIF really better than WebP?

Usually, for compression: at the same visual quality AVIF files come out meaningfully smaller than WebP, especially on photos and gradients. WebP still wins on encode speed and universality in older software. Since both convert in seconds here, the practical answer is: try AVIF first, keep WebP as the fallback.

Do browsers support AVIF in 2026?

Yes — Chrome, Firefox, Safari, and Edge all display AVIF natively, covering the overwhelming majority of web traffic. For belt-and-braces delivery, serve AVIF inside a picture element with a WebP or JPG fallback; older mail clients and some apps still don't decode it.

Will my PNG's transparency survive?

Yes. AVIF supports a full alpha channel, so transparent and semi-transparent pixels convert faithfully — logos and cutouts keep their clean edges. That's a genuine advantage over JPG, which would flatten your transparency onto a background color.

Is PNG to AVIF conversion free?

Yes — converting images to AVIF is part of the free tier: no signup, no watermark, files up to 100 MB. The Pro upgrade adds a lossless AVIF mode, AVIF stills from video frames, batch conversion, and a permanent library, as a one-time purchase.

When should I stick with PNG?

Keep PNG when a tool in your pipeline demands it — some design apps, printers, and legacy CMSes only ingest PNG — or when you truly need lossless interchange between editors. For anything a browser displays to a visitor, AVIF or WebP is almost always the better citizen.

To convert a PNG to AVIF, upload the image, pick your quality, and download — free, no account, and the transparency your PNG carries comes along intact. AVIF is the newest mainstream image format, built on the AV1 video codec, and it routinely cuts file sizes to a fraction of an equivalent PNG or JPG while holding more visual detail than WebP at the same weight.

PNGs are the usual suspects behind slow pages: screenshots, UI mockups, logos exported at full resolution, design-tool output that nobody compressed. PNG's lossless compression is honest but ancient — it simply can't compete with a modern codec. Converting to AVIF keeps the crispness (and the alpha channel) while shrinking the transfer dramatically, which shows up directly in your Largest Contentful Paint and PageSpeed scores.

Every current major browser — Chrome, Firefox, Safari, Edge — displays AVIF natively. For maximum-compatibility fallbacks you can convert the same PNG to WebP here too and serve both from a picture element.

The smallest mainstream format

AVIF compresses with AV1, the same technology behind next-gen video streaming. On photographic content it typically beats WebP and demolishes PNG and JPG at comparable quality — the same screenshot that ships as an 800 KB PNG can land in the low tens of kilobytes.

Transparency included

AVIF carries a full alpha channel, so transparent PNGs — logos, product cutouts, UI elements — convert with soft edges intact. You keep the exact use-case that made you export a PNG in the first place, at a size that no longer hurts your page.

Quality is in your hands

The quality slider maps to the encoder's constant-quality mode, so you decide the size-versus-fidelity balance and can re-export in seconds. Pro users also get a lossless mode for pixel-identical output — for the rare cases where identical actually matters.
