Convert RAF to AVIF Online — Fujifilm RAW to AVIF

RAF (RAw Fujifilm) is Fujifilm's proprietary RAW image format used by X-series and GFX medium format cameras. RAF files store unprocessed 14-bit sensor data, including from Fujifilm's unique X-Trans CMOS sensors (used in most X-series cameras) which use a non-Bayer color filter array that reduces moire and false color without optical low-pass filters. This results in exceptional sharpness and color rendition renowned among photographers.

RAF is the standard RAW format for popular Fujifilm cameras including the X-T5, X-H2, X-H2S, X-Pro3, X100VI, and the medium format GFX 100S and GFX 100 II. Fujifilm's acclaimed film simulations are embedded as metadata. For sharing or web publishing, conversion to JPEG is necessary since RAW formats require specialized software like Adobe Lightroom, Capture One, or Fujifilm's X Raw Studio.

AVIF (AV1 Image File Format) leverages the AV1 video codec to deliver next-generation compression—typically 50% smaller than JPEG at equivalent quality, with support for HDR, wide color gamut, and both lossy and lossless compression. Standardized by the Alliance for Open Media in 2019, AVIF offers 10-bit and 12-bit color depth plus full alpha transparency. Encoding is slower than JPEG or WebP, but visual quality per byte is exceptional.

AVIF is ideal for modern web delivery where cutting-edge compression and HDR support matter. Browser adoption reached critical mass in 2021-2023, with Chrome 85+, Firefox 93+, and Safari 16.4+ now supporting AVIF natively. Encoding is 2-3× slower than WebP, but the compression gains typically justify the extra CPU time for server-side batch processing. For maximum compatibility, serve AVIF with WebP and JPG fallbacks using <picture> elements.
