About This Conversion
AVIF provides the best compression ratio available for photographic images today. Converting JPG to AVIF typically produces files 30-50% smaller at equivalent visual quality. This makes AVIF the best choice for image-heavy websites focused on Core Web Vitals performance. The format is based on the royalty-free AV1 codec, supports 10-bit and 12-bit color depth, HDR, and wide color gamuts. While AVIF encoding is computationally intensive, this tool handles it efficiently in your browser using the Canvas API.
Frequently Asked Questions
How much smaller is AVIF compared to JPG?
AVIF is typically 30-50% smaller than JPEG at equivalent quality. A 100KB JPG often compresses to 50-70KB as AVIF with no visible quality difference.
Is AVIF better than WebP?
For most photographs, yes. AVIF achieves 20-30% better compression than WebP. However, WebP has broader browser support. Consider serving AVIF with WebP fallback via <picture>.
Is encoding slow?
AVIF encoding is computationally heavier than JPG or WebP. This tool handles it in your browser, which may take a few seconds for large images. The smaller output files are worth the wait.
