Should I use AVIF or WebP for my website?

Use both with the ` ` element: serve AVIF to browsers that support it, fall back to WebP, and fall back to JPEG. This approach serves the most efficient format to each visitor. AVIF for modern browsers, WebP as a middle fallback.

What types of images benefit most from AVIF?

AVIF excels at: photographs with gradients and complex detail, images with flat areas of color, HDR and wide-gamut content. It is less beneficial for: simple flat icons (SVG is better), text-heavy images (PNG lossless is clearer), and animated content.

Can I use AVIF for e-commerce product images?

Yes, and it is highly recommended. AVIF's superior compression reduces product image sizes dramatically, improving mobile page speed. Use it as the primary format with JPEG fallback for older browsers. Shopify and major CDNs now support automatic AVIF conversion.

Are converted files private?

Yes. Files are processed on Cloudflare R2 infrastructure, not shared with third parties, and automatically deleted after 24 hours. Do not upload confidential or personal images — use this tool for web assets and public-facing images only.

How do I use AVIF in Next.js?

Next.js Image component serves AVIF automatically when you add `formats: ["image/avif", "image/webp"]` to `next.config.js`. The component negotiates the best format per browser via the Accept header. No manual conversion needed for images used through the Next.js Image component.

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.

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It offers the best compression of the mainstream web formats, supports transparency and HDR, and is supported by Chrome, Edge, Firefox, Safari 16+, and Opera.

Does converting JPG to AVIF lose quality?

JPG is already a lossy format, so an AVIF re-encode at a moderate quality setting is visually excellent while the file is much smaller. AVIF compresses far more efficiently than JPEG, so a quality of 50 to 65 gives a dramatic size saving with no noticeable loss.

Which browsers can convert JPG 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 JPG is never uploaded, stored, or sent anywhere — the conversion and download happen locally on your device.

Is AVIF better than WebP for JPG photos?

AVIF generally compresses photographs better than WebP, producing smaller files at the same quality. WebP has slightly broader browser support. For modern, performance-focused sites AVIF is usually the better choice, ideally with a WebP or JPEG fallback for older browsers.

Treating AVIF quality numbers like JPEG qualityAVIF quality 90 set for "high quality" — file barely smaller than JPEG

AVIF quality scale is non-linear. Quality 62 AVIF produces results comparable to quality 85 JPEG. Start at 55–65 and only increase if specific artefacts appear in your test images.

Serving AVIF without fallback in HTML`<img src="product.avif">` — fails in Safari 15 and Opera Mini

Always wrap AVIF in `<picture>` with WebP and JPEG fallbacks. 92% browser support means 1 in 12 visitors cannot display AVIF. The `<picture>` pattern costs one line of HTML.

Converting already-compressed JPEG thumbnails to AVIFUploading a quality-50 JPEG and converting to AVIF

Always convert from the highest-quality JPEG source available. Compressing a low-quality JPEG amplifies existing artefacts. Start from the original camera output or a 90+ quality JPEG.

Using AVIF for email marketing imagesE-commerce email with AVIF product photos

Email clients (Outlook, Gmail on Windows) do not support AVIF or WebP. All email images must be JPEG or PNG. Use AVIF only for web browser contexts.

Expecting AVIF lossless to outperform PNG in all casesSimple screenshot converted to AVIF expecting smaller file than PNG

For screenshots and text-heavy images, PNG lossless is often comparable to AVIF lossless. AVIF shines with photographs and complex colour gradients, not flat-colour UI screenshots.

Not implementing AVIF at the CDN level for high-traffic sitesIndividual images manually converted — no automated delivery

For high-traffic sites, configure your CDN (Cloudflare Images, Imgix, or AWS CloudFront) to auto-convert and cache AVIF on request. Manual conversion doesn't scale beyond a few hundred images.

FAQ

Frequently asked questions

AVIF is typically 40–50% smaller than JPEG at equivalent visual quality. A 200KB JPEG photograph often converts to 90–120KB AVIF. For a site with 100 product images averaging 200KB, switching to AVIF saves ~10–11MB per page load.
