How to Convert WebP to AVIF?

Upgrade your images to the newest web standard. Better quality, smaller file sizes.

1

Upload WebP

Drag and drop your files. We support batch processing to convert multiple images at once.

2

Choose Quality

Select 'High' for max fidelity or 'Small' for the best compression ratio.

3

Download AVIF

Get your ultra-compact AVIF files, ready for modern browsers and applications.

Pro Tip: Browser Support

AVIF is supported by all modern browsers (Chrome, Firefox, Safari). It is the successor to WebP and offers superior compression, especially for complex textures.

Engineering Philosophy

Beyond WebP.
The Power of AV1.

WebP was a revolution, but AVIF is the evolution. Built on the AV1 video codec, AVIF offers up to 30% better compression than WebP while maintaining higher visual fidelity.

Our converter uses the advanced libavif encoder. It partitions your image into variable-sized blocks and applies 64 different prediction modes to find the most efficient way to represent pixels.

The result is an image that is smaller, sharper, and supports wider color gamuts (HDR) than its predecessors. We process everything in a stateless, secure environment to ensure your data never lingers.

Built for Performance

AV1 Codec

Leverages next-gen video compression for stills.

HDR Ready

Supports 10-bit and 12-bit color depth.

Next-Gen Web Format

Standardized by the Alliance for Open Media

Why Switch from WebP to AVIF?

WebP was introduced by Google in 2010 to replace JPEG and PNG. It did a great job. But in 2019, the Alliance for Open Media released AVIF (AV1 Image File Format), which is a game-changer.

AVIF typically produces files that are 20-30% smaller than WebP for the same visual quality. It avoids the "blocky" artifacts seen in WebP at low bitrates, instead producing a smoother, more pleasing blur that retains more detail.

If you are optimizing a website for Core Web Vitals (LCP) or trying to save bandwidth costs, converting your library to AVIF is the most impactful step you can take today.

How It Works

AVIF brings technologies from video compression into still images. It supports multi-threading (faster decoding), chroma subsampling control, and film grain synthesis—features that WebP lacks.

Our tool handles these complex parameters automatically. When you choose "Balanced" quality, we target a perceptual quality that matches the original image while aggressively removing redundant data.

Key Terminology

AV1

A royalty-free video coding format designed for video transmissions over the Internet.

Artifacts

Visible defects in an image caused by lossy compression. AVIF handles these better than WebP.

Bit Depth

The number of bits used to indicate the color of a single pixel. Higher depth means smoother gradients.

Lossless

Compression where no data is lost. AVIF supports both lossy and lossless modes.
