What is AVIFS?

AVIFS (image/avif-sequence) uses lossy compression optimized for modern web animations, high-efficiency image sequences. AVIF Sequence, animated AVIF image format for modern web

What is NEF?

Nikon Electronic Format (NEF) is Nikon's raw image format containing unprocessed sensor data from Nikon D-Series and mirrorless cameras.

When Should You Use AVIFS vs NEF?

AVIFS vs NEF: Key Differences

• •The core technical difference: AVIFS relies on lossy compression whereas NEF uses lossless compression.
• •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
• •Transparency: N/A
• •NEF files tend to be differently sized than AVIFS
• •AVIFS is optimized for modern web animations, high-efficiency image sequences while NEF is designed for nikon photography, professional post-processing — choose based on your specific workflow needs

Advantages of AVIFS

• ✓The lossy nature of AVIFS means file sizes stay reasonable while handling Modern web animations, high-efficiency image sequences efficiently.
• ✓From mobile devices to enterprise servers, AVIFS is recognized and supported everywhere.
• ✓Storage and bandwidth costs drop significantly when using AVIFS thanks to its efficient compression.
• ✓AVIFS is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of NEF

• ✓NEF applies lossless compression specifically calibrated for Nikon photography, professional post-processing.
• ✓NEF enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓NEF guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find NEF support built into virtually every tool that handles Nikon photography, professional post-processing — no plugins or converters needed.
