Canon RAW 3
The modern, efficient raw format for Canon's mirrorless era.
CR3 is the current raw image format used by Canon's EOS R mirrorless cameras and newer DSLRs. Introduced in 2018 with the EOS M50, it completely replaces the older CR2 format. The biggest innovation in CR3 is the introduction of 'C-RAW' (Compact Raw). This is a lossy compression option that reduces file sizes by up to 40% with virtually no visible loss in image quality. This allows photographers to shoot longer bursts, save hard drive space, and transfer files faster without sacrificing the flexibility of raw editing.
Unlike CR2, which was based on TIFF, CR3 is based on the CIFF (Camera Image File Format) structure, which is related to the MP4 container. This modern architecture allows for faster reading/writing and better metadata handling. CR3 files store 14-bit sensor data. In standard mode, it uses lossless compression. In C-RAW mode, it uses a smart lossy algorithm that prioritizes highlight and shadow detail while compressing midtones.
As sensor resolutions jumped from 20MP to 45MP+ (like in the EOS R5), file sizes became unmanageable. CR2 files were getting too big. Canon developed CR3 to solve this storage bottleneck, launching it alongside their push into full-frame mirrorless cameras.
Quite OK Image Format
Lossless compression that is incredibly fast.
QOI (Quite OK Image Format) is a modern lossless image format created by Dominic Szablewski in 2021. It was designed to be a simpler, faster alternative to PNG, prioritizing encoding and decoding speed over maximum compression ratio.
The QOI specification fits on a single page of paper. It achieves compression ratios similar to PNG but encodes 20x-50x faster and decodes 3x-4x faster. It uses a simple streaming algorithm with a running array of previously seen colors.
Released in 2021 as a reaction to the complexity of formats like PNG and the slowness of their reference implementations. It quickly gained viral popularity in the developer community.
