Foire aux questions
What is AVIF and why use it over WebP?
AVIF (AV1 Image File Format) is a next-generation image format that uses AV1 compression technology. It can produce images up to 50% smaller than WebP at the same quality level, and supports modern features like HDR and wide color gamut. For the same visual quality, AVIF files are typically 30-50% smaller than WebP, making it the ideal format for modern web performance.
Will I lose quality converting WebP to AVIF?
AVIF uses lossy compression, so there is some quality loss. However, at high quality settings (80+), the difference is visually imperceptible for most images. AVIF's AV1 codec is significantly more efficient than WebP, meaning you get smaller files at comparable quality. For web use, quality 80-85 with maximum compression produces stunning results at a fraction of the original WebP file size.
Which browsers support AVIF?
AVIF is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and all Chromium-based browsers like Edge and Opera. The format is also supported by most major image editing tools and operating systems. Check caniuse.com for the latest browser support information.
Can I convert multiple WebP files at once?
Yes, batch conversion is fully supported. Select a whole folder of WebP images and convert them all at once. Each image is processed independently using wasm-vips right in your browser, and you can download them individually or click 'Download All AVIF' to get everything in one go. There is no limit on the number of files.
