Canon Raw 2
CR2 is a Canon camera raw format with TIFF-based organization. It holds camera image data and metadata for later development rather than only the camera’s finished JPEG. It is distinct from Canon’s earlier CIFF-based CRW and later CR3 files; those extensions identify different storage structures and decoding requirements.
Raw precision and reduced-size recording modes depend on the camera. A lossless compression stage does not imply that a reduced-size raw has identical data to a full-resolution capture. Use the camera documentation and a decoder that supports that exact model and mode.
Use the raw original for repeated photographic development when exposure interpretation and colour decisions need to remain flexible. Export JPEG for an opaque delivery image or a suitable high-precision raster for further editing. Those exports bake in processing choices and cannot recreate the original sensor data, calibration or all vendor metadata.
Raw development interprets capture values using colour calibration, white balance and a tone curve; mosaiced data also needs demosaicing. A built-in preview is already rendered and can look different from a fresh raw development. More bit depth does not recover clipped exposure or establish a ready-to-display HDR image.
Raw precision and reduced-size recording modes depend on the camera. A lossless compression stage does not imply that a reduced-size raw has identical data to a full-resolution capture. Use the camera documentation and a decoder that supports that exact model and mode.
Raw formats evolve alongside camera sensors, recording modes and development software. These milestones connect this format family to the camera and processing workflows that use it.
Different formats, different trade-offs. Choose for the image and the workflow.
DNG provides a published container for camera raw data and calibration information. It can simplify supported raw interchange, but conversion does not guarantee that every proprietary maker note or processing feature will remain usable.
JPEG makes a compact photographic delivery file, but ordinary JPEG discards detail and has no alpha. Keep the richer source for editing and use JPEG when the receiving workflow expects an opaque photo.
TIFF provides tagged raster storage with multiple images and several sample types and compression schemes. It is a useful interchange choice for scanning and high-precision editing, but the receiving tool must support the particular TIFF variant.
PNG preserves decoded pixels losslessly and can carry alpha. It is useful for transparent graphics and screenshots; it does not preserve editable document layers or camera sensor data, and photographic files can be large.

Renaming changes no data. CR3 uses a different structure, and JPEG is a rendered export. Use a supported raw-development workflow to produce a delivery image.
Check the exact camera model and recording mode in the processor’s support list. Raw support is model-specific, even when the extension is recognised. Viewing an embedded JPEG preview does not prove the sensor data has been decoded.
Raw-to-image export develops the data: white balance, colour mapping and tone become part of the pixels. Grayscale, palette and SDR targets can discard additional information. Keep the original; converting a rendered image back into a raw container cannot reconstruct the capture.
