NEF (Nikon Electronic Format) is Nikon's proprietary RAW image format used by all Nikon DSLRs and mirrorless cameras since 1999. Built on TIFF structure, NEF stores unprocessed 12-bit or 14-bit sensor data, preserving maximum dynamic range and color information for post-production flexibility. Files include embedded JPEG previews and comprehensive EXIF metadata including lens data, focus point, and metering information.

NEF is essential for photographers using Nikon cameras who need maximum editing flexibility. For sharing or web publishing, conversion to JPEG is necessary since RAW formats require specialized software like Adobe Lightroom, Capture One, or Nikon's own ViewNX-i and NX Studio applications.
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.
Authoritative reference: AVIF Specification (AOMedia)
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.
