Is AVIF supported by all browsers?

AVIF is supported in Chrome 85+, Firefox 93+, Opera 71+, and Safari 16.4+. Internet Explorer and older Safari versions do not support AVIF. Use the ` ` element with WebP and JPEG fallbacks for full cross-browser support.

AVIF vs WebP — which is better?

AVIF compresses better (typically 20–30% smaller than WebP at the same quality). WebP has better browser compatibility and faster encoding. For cutting-edge performance with modern-browser audiences, AVIF is the better choice.

What quality should I set for AVIF?

AVIF quality settings behave differently from JPEG/WebP. Quality 50–70 (on a 0–100 scale) typically produces excellent results. Quality 40 is often barely distinguishable from quality 80, making AVIF very efficient at lower quality settings.

Is AVIF encoding slow?

Yes. AVIF encoding is significantly slower than JPEG and WebP (2–10× slower depending on settings and hardware). This is why it is not practical for real-time image processing. For static assets, pre-convert and serve from CDN. This tool handles the slow encoding server-side.

How do I implement AVIF with fallback in HTML?

Use the ` ` element: ` `. Browsers pick the first supported format — AVIF if available, WebP as fallback, JPEG for full compatibility.

Is my uploaded image processed privately?

Yes. Images are uploaded to Cloudflare R2 for server-side encoding, automatically deleted after 24 hours, and never shared with third parties. Do not upload confidential or personal images — use this tool for web assets only.

How much smaller is AVIF than PNG?

AVIF is typically up to 50 percent smaller than PNG, and often more for photographic content, while keeping excellent visual quality. The exact saving depends on the image and the quality setting you choose.

Does converting PNG to AVIF lose quality?

AVIF compresses very efficiently, so even at a moderate quality setting the result is visually excellent. AVIF also supports a lossless mode. For web use, a quality of 50 to 65 gives a dramatic size saving with no noticeable loss.

Which browsers can convert PNG to AVIF?

This converter encodes AVIF directly in the browser, which requires a Chromium-based browser such as Chrome, Edge, Brave, or Opera. Firefox and Safari can display AVIF but cannot encode it via the HTML canvas, so use Chrome or Edge to run the conversion.

Are my images uploaded to a server?

No. This converter runs entirely in your browser using the HTML canvas. Your PNG is never uploaded, stored, or sent anywhere — the conversion and download happen locally on your device.

Does AVIF support transparency?

Yes. AVIF supports an alpha channel, so transparent PNGs keep their transparency when converted to AVIF — the same as WebP, and unlike JPEG.

Applying JPEG quality scale intuition to AVIFAVIF quality 80 expected to be "high quality" — results in huge file

AVIF quality 60 matches JPEG quality 85 visually. AVIF quality 40 is still excellent. Start at quality 50–65 and increase only if you see specific artefacts.

Using AVIF for images viewed in email clientsNewsletter banner converted to AVIF

Email clients do not support AVIF or WebP. Use JPEG for all email images. AVIF is for web browser delivery only.

Not providing WebP and JPEG fallbacks in HTMLOnly `<img src="image.avif">` — fails in Safari 15 and older Firefox

Use `<picture>`: AVIF first, WebP as middle fallback, JPEG as universal fallback. AVIF is 92%+ supported but the `<picture>` pattern is the correct implementation.

Trying to convert AVIF in real time at request timeServer converting PNG to AVIF on every image request

AVIF encoding takes 2–10× longer than JPEG. Pre-convert and cache the AVIF files. Use a CDN or image CDN (Cloudflare Images, Imgix) for on-demand conversion with caching.

Uploading very large PNG source files above 10MB25MB PNG from design tool — upload rejected

Resize to your actual display dimensions first. A 2000px wide image is sufficient for most web use. Export at the target size before converting.

Expecting AVIF to outperform SVG for simple iconsSimple flat icon converted from SVG → PNG → AVIF

SVG is resolution-independent and often smaller than AVIF for simple vector graphics. Use SVG for icons and logos; reserve AVIF for photographs and complex raster images.
