Camera-RAW development and image encoding: How CR2 becomes PNG

Demosaicing, white balance, tone, orientation, and color interpretation all run against the sensor-oriented CR2 data before PNG encoding even starts. What comes out is a rendered photograph, never another untouched camera negative. The Canon CR2 reader locates raw sensor strips and the embedded preview inside its TIFF-based structure before photographic development begins. PNG delivery preserves exact raster samples with optional full alpha and color metadata, but file size, palette reduction, animation absence, and profile handling still vary.

Decoded canvas - Canon's TIFF-based raw generation containing sensor data and an embedded preview. Written image - Pixels written losslessly with a full alpha channel available.

When to actually choose CR2 to PNG

PNG wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than CR2 does.

What changes between the CR2 model and the PNG deliverable

PNG supports alpha transparency that CR2 never had, so any transparent areas in the result are newly created, not carried over from the source.
Treat CR2-specific metadata fields as optional in the PNG result until you have actually confirmed they survived.

CR2 source facts versus PNG output requirements

What can fail when CR2 camera raw image is interpreted

Canon Picture Styles and Digital Lens Optimizer adjustments are not guaranteed in a generic rendering.

What Portable Network Graphics cannot safely promise

PNG is a poor fit for photographic detail, and even without any JPEG-style loss, palette reduction can visibly simplify a smooth gradient.

How the PNG writer handles this route

pixels written losslessly with a full alpha channel available is what gets written, labeled as image/png. Whether that actually opens depends on the receiving application, not on the file extension.

Checking the PNG result before you trust it

Record the CR2 evidence before conversion

Check white balance, highlight recovery, lens geometry, orientation, and EXIF against Canon's reference rendering.

Test the PNG file in its receiving workflow

Zoom to 100% on transparent edges, gradients, and small text, and confirm the exact pixel dimensions.
