WOFF to AVIF conversion is the process of transforming web font files in WOFF (Web Open Font Format) into AVIF (AV1 Image File Format) images or image-like assets, typically by extracting glyphs or rendered text and encoding them as AVIF pictures. This conversion is used when designers or developers need font glyphs rasterized as highly compressed images for web or app use, leveraging AVIF's superior compression and color fidelity.

WOFF files use the MIME type font/woff and are mainly used for embedding web fonts in browsers. AVIF files use the image/avif MIME type and are based on the AV1 video codec for advanced image compression. While WOFF handles font data, AVIF files are optimized for high-quality, compressed images suitable for web use.
The AVIF (.AVIF) format is commonly used for other. Understanding its characteristics can be helpful when converting to or from other formats like WOFF.

WOFF is primarily a font file format designed for web typography, while AVIF is an advanced image format focused on high compression and image quality. Converting WOFF to AVIF changes the file type from a font to an image, useful for specific design or optimization needs. AVIF offers better compression and quality compared to older image formats but serves a different purpose than WOFF fonts.
Keep rasterized glyph images small: aim for 1–50 KB per glyph image for UI icons; larger decorative text may be 50–500 KB depending on resolution.
Preserve quality by exporting at the target display resolution and using lossless or high-quality (80–100) AVIF for fine typography to avoid jagged edges.
For batch conversion, generate a glyph sprite sheet or multi-frame AVIF to reduce overhead and streamline CSS/asset management.
Limitations: WOFF is a vector font format—converting to AVIF rasterizes vectors to pixels, losing scalability and hinting; keep original WOFF/WOFF2 for responsive text rendering.
