How do I convert WEBP to AVIF online step by step?

Upload your WEBP files to the converter, select AVIF as the output format, adjust quality (0-100) and chroma subsampling if needed, then click Convert. After conversion, download the AVIF files to your device. The tool supports batch conversion and preserves transparency automatically.

Why convert WEBP to AVIF? What are the real-world benefits?

AVIF uses the AV1 codec, offering 20-50% better compression than WEBP at the same quality. It supports HDR, wide color gamut, and transparency, making it ideal for web images. However, AVIF is not supported in older browsers; check compatibility before deploying globally.

How does the conversion handle transparency, color profiles, and metadata?

Transparency (alpha channel) is fully preserved when converting WEBP to AVIF. Color profiles are converted to sRGB or P3 based on your settings; metadata (EXIF) is stripped by default to reduce size, but you can toggle to keep it. Resolution is retained, but animated WEBP is not supported—only the first frame is converted.
