Does Next.js serve AVIF automatically?

Yes. Next.js's built-in Image component serves AVIF automatically when the browser supports it, and falls back to WebP for others. You can configure the output formats in next.config.js under the images.formats array — set it to ['image/avif', 'image/webp'] to enable both.

Upgrade WebP to AVIF — 20–30% More Compression

AVIF is WebP's successor — 20–30% better compression at equivalent quality. If you have a WebP image library and want to upgrade for even better web performance, converting to AVIF gives you the smallest possible images for modern browsers. E-commerce sites can save significant bandwidth upgrading from WebP to AVIF.

Upgrading from WebP to AVIF: 20–30% More Compression

WebP was Google's major step forward from JPEG — smaller files, transparency support, and broad browser adoption. But AVIF is WebP's successor, built on the AV1 video codec. At equivalent visual quality, AVIF files are consistently 20–30% smaller than WebP. For photographic content, gradients, and fine detail, the gap is clearly visible when you compare them side by side at the same file size.

Chrome 85+, Firefox 93+, and Safari 16+ all support AVIF — covering the overwhelming majority of browsers in use today. Next.js's Image component serves AVIF automatically when supported. Cloudinary's f_auto parameter does the same. E-commerce sites with hundreds of product images can see meaningful bandwidth reductions and LCP improvements from upgrading their WebP library to AVIF.

How to Convert WebP to AVIF

Open the Converter

Click "Convert Now" — the image tab with WebP → AVIF will be pre-selected.

Add Your WebP Files

Drag and drop your .webp files or click to browse. Enable Batch mode for multiple images.

Set Quality

Choose AVIF quality (75–85 for web images). AVIF's codec is more efficient — lower settings still look great.

Download Your AVIFs

Converted files download immediately — ready to deploy with WebP fallback via picture element.

Where AVIF Delivers the Most Value Over WebP

🛒

Product Images

E-commerce product galleries have hundreds of images. 20–30% smaller files across the board adds up to significant bandwidth savings.

⚡

Core Web Vitals

Smaller above-the-fold images directly reduce LCP (Largest Contentful Paint) — a key Google ranking factor.

⚛️

Next.js Projects

Set images.formats to ['image/avif', 'image/webp'] in next.config.js. The Image component handles AVIF serving automatically.

☁️

Cloudinary

f_auto in Cloudinary URLs automatically serves AVIF to supported browsers. Just upload your source image and let Cloudinary handle the rest.

Hero Images

Large hero and banner images benefit most from AVIF's superior compression — fewer bytes for the same visual impact.

Frequently Asked Questions

For photographic content, AVIF is typically 20–30% smaller than WebP at the same visual quality. The gap is most visible in images with gradients, fine texture detail, and smooth color transitions. For flat-color graphics or simple illustrations, the difference is smaller. At the same file size, AVIF will look noticeably sharper.

Safari 16+ (macOS Ventura and later) and iOS 16+ support AVIF. For users on iOS 14 or 15, AVIF is not supported — serve a WebP fallback using a picture element: add a source with type="image/avif" pointing to the AVIF file, then an img tag pointing to the WebP. Modern browsers get AVIF, older ones get WebP automatically.

For new images, yes — always generate AVIF as your primary format with a WebP fallback for older browsers. For existing image libraries, weigh the bandwidth savings against the conversion effort and storage costs. E-commerce sites with large product image catalogs see the most benefit from a WebP-to-AVIF migration.

Yes. Next.js's built-in Image component serves AVIF automatically when the browser supports it, and falls back to WebP for others. Configure the output formats in next.config.js under the images.formats array — set it to ['image/avif', 'image/webp'] to enable AVIF-first serving with WebP as fallback.

Yes — both formats are lossy, so converting from WebP to AVIF introduces another generation of encoding loss. The degradation is minimal at high quality settings (85+), but it is a second encode. For best results, always convert from the original JPEG, PNG, or RAW source rather than from an already-compressed WebP.

Yes. Cloudinary's f_auto transformation parameter automatically serves AVIF to browsers that support it, WebP to those that don't, and JPEG as a universal fallback. This means you don't need to manually convert — Cloudinary handles format selection at delivery time. Just upload your original image and use f_auto in the URL.
