Canon Raw 3
CR3 is Canon’s newer raw representation, documented for cameras such as the EOS M50. It stores image data for development and capture metadata rather than an ordinary rendered JPEG. The container differs from TIFF-based CR2 and CIFF-based CRW; a shared camera brand is not enough to guarantee the same decoder can open all three.
RAW and C-RAW are recording choices inside the CR3 workflow. Canon describes C-RAW as a smaller raw representation, but its exact processing and availability depend on the model. Do not infer identical sample retention or a fixed bit depth from .cr3 alone.
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 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.

Both can use .cr3. Inspect camera recording settings and file metadata; the extension is not a compression-mode declaration.
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.
