Benefits of Converting WebP to AVIF
While WebP is a modern and efficient format, AVIF (AV1 Image File Format) takes image compression to the next level:
- Even Smaller File Sizes: AVIF often achieves significantly smaller file sizes than WebP (and JPG/PNG) at comparable or even higher visual quality.
- Faster Loading: Smaller files mean faster image downloads and quicker page load times, improving user experience and SEO.
- High Quality: AVIF supports a wide color gamut, high dynamic range (HDR), and transparency, making it suitable for a broad range of photographic and graphic content.
- Future-Proof: Backed by the Alliance for Open Media (AOMedia), AVIF is a royalty-free format designed for the future of web media.
- Transparency Support: Like WebP, AVIF fully supports alpha channels, preserving transparency from your source images.

Frequently Asked Questions
Will AVIF always be smaller than WebP?
In most cases, yes. AVIF's compression algorithm is generally more advanced than WebP's, allowing it to achieve smaller file sizes at comparable or even higher visual quality. However, the exact size reduction depends on the image content and the quality settings chosen.
Is AVIF supported by all browsers?
AVIF is supported by all major modern browsers, including Chrome, Firefox, Edge, and Safari (since iOS 16/macOS Ventura). Older browsers might not support it, but its adoption is rapidly growing.
Why does the AVIF encoder take time to load?
Browsers do not natively support AVIF encoding. This tool uses a client-side WebAssembly (WASM) library to perform the conversion. This library is loaded on demand to keep the initial page load fast. The loading time depends on your internet speed and the size of the encoder module.
Are my images uploaded to a server?
No, all image conversions are performed directly in your web browser using the loaded WebAssembly module. Your files are not sent to any external server, ensuring your privacy and security.
