Convert to AVIF

Encode JPEG/PNG/TIFF to AVIF. AVIF beats WebP on compression ratio and supports 10/12-bit, HDR, and lossless modes. Browser support is universal as of 2024 (Chrome 85+, Firefox 113+, Safari 16.4+).

When to use

• Web-prep where modern browser support is fine.
• Archival of high-bit-depth photos (10/12-bit AVIF preserves more than JPEG).
• Pre-step inside web-ready orchestrator.

Do not use this skill when:

• Output must work in Safari <16.4 / IE / very old Android browsers — fall back to WebP or JPEG.
• Source is already AVIF — no point re-encoding.
• You need lossless re-encoding of a JPEG that should remain bit-exact-decodable — that's convert-to-jxl's unique trick, not AVIF's.
