JPG转AVIF技巧
为什么从JPG切换到AVIF
JPG has been the web standard for decades, but AVIF is its successor. AVIF uses the AV1 video codec to compress images 30-50% more efficiently than JPG at equivalent quality. For websites, this means faster page loads, lower bandwidth costs, and better Core Web Vitals scores — especially on image-heavy pages. Your users on mobile data plans will thank you.
快速编码与最大压缩
"Fast Encoding" (speed 6, quality 80) processes images quickly for everyday use — great for drafts, social media, or when you need results now. "Maximum Compression" (speed 0, quality 50) takes longer but produces the absolute smallest AVIF files, ideal for archival or when every byte matters. Try both to see which balance of speed and size works for your project.
何时使用AVIF而非JPG
AVIF is perfect for web images, especially photographs and complex graphics where file size matters. Use it for hero images, product photos, backgrounds, and UI assets on modern websites. AVIF's superior compression means you can serve higher quality images at lower file sizes compared to JPG, with broad browser support including Chrome, Firefox, and Safari.
常见问题
What is AVIF and why use it over JPG?
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 JPG 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 JPG, making it the ideal format for modern web performance.
Will I lose quality converting JPG 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 including photos. AVIF's AV1 codec is significantly more efficient than JPEG, meaning you get smaller files at comparable quality. For web use, quality 80-85 with maximum compression produces stunning results at half the JPG 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 JPG files at once?
Yes, batch conversion is fully supported. Select a whole folder of JPGs 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.
