What is X3F?

Sigma Raw (X3F) contains raw sensor data from Sigma cameras using the unique Foveon X3 sensor technology.

What is WEBP2?

WebP2 is the next-generation image format from Google, building on the success of WebP with significantly improved compression efficiency. It targets 30% additional size reduction over WebP at equivalent quality.

When Should You Use X3F vs WEBP2?

Use X3F When...

Reach for X3F when your priority is sigma/foveon camera raw processing — its uncompromising quality ensures every detail is preserved.

Use WEBP2 When...

Reach for WEBP2 when your priority is high-efficiency web graphics, next-gen responsive images — its efficient compression makes sharing fast and storage minimal.

X3F vs WEBP2: Key Differences

  • •The core technical difference: X3F relies on lossless compression whereas WEBP2 uses lossy compression.
  • •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
  • •Transparency: Full alpha channel with improved compression efficiency — converting from X3F will merge transparency into a solid background
  • •X3F files are typically 25-60MB per photo while WEBP2 files range 30-50% smaller than JPEG, 15-20% smaller than WebP
  • •Use case fit: X3F targets sigma/foveon camera raw processing and WEBP2 targets high-efficiency web graphics, next-gen responsive images — your choice depends on which workflow stage you are serving.
