CR3 is what Canon's cameras have recorded since 2018: the EOS R mirrorless bodies, the later M series, and recent PowerShots. It replaced CR2. A CR3 holds the sensor's raw readings, which need to be developed before they are a picture, and very little software outside Canon's own and dedicated RAW editors can do that. This page turns a CR3 into a JPG.
The file is developed with LibRaw, the open-source library many RAW editors are built on. The white balance the camera chose at the moment of the shot is applied, the colours are converted to sRGB, and a picture taken with the camera on its side comes out upright. You choose the JPG quality; resizing and cropping are available in the same editor.
Developing RAW files is part of the Pro plan, because it costs far more computing time than converting an ordinary picture. A free visitor is told so before anything is uploaded. We tested the reader with a real file from an EOS R6, which developed with correct colours, and the results of that test shape what is said below about very new cameras.
What is different about CR3
CR2 was built on the TIFF format. CR3 is built on the same container as MP4 video and HEIC photos, with the image data compressed by a newer method. That brought C-RAW, a lossy RAW option roughly forty percent smaller than a full CR3, which looks identical in all but extreme edits. Both kinds are read here, and the result is the same kind of JPG.
The change of container is why older programs that open CR2 without complaint show nothing for CR3. Updating the program helps where an update exists; converting helps everywhere.
Brand-new cameras
Each new camera needs its own entry in a RAW library: the sensor's layout, its black level, its colour response. A library release from before the camera cannot know them. Our test found one such case, a body released in the past year, which the library developed with wrong colours. A check catches this, and the full-size JPG that the camera itself stored inside the CR3 is returned instead, with a note that it is the camera's own preview.
That embedded picture is a real photograph at full resolution, processed by the camera. What you lose is only the chance to develop the raw data differently.
What a developed JPG does not include
Canon's Picture Styles, lens corrections and noise reduction are applied by the camera or by Canon's software, not stored as finished pixels in the raw data. A neutral development therefore looks a little flatter and less sharpened than the JPG the camera would have made, and may show the lens's natural vignetting. For a quick, shareable copy that is fine; for a finished photograph, edit the RAW in a RAW editor.
Size and speed
A CR3 from a current body is 20 to 45 megabytes and holds 24 to 45 megapixels. Developing one takes a second or two after the upload. If the picture is larger than the pixel limit, it is developed at half size and you are told. The JPG at quality 90 is usually a quarter to a third of the CR3's weight.
Frequently asked questions
Why is CR3 conversion a Pro feature?
Developing a RAW file takes many times the computing work of converting a finished picture. The Pro plan covers that cost.
Does it read C-RAW files?
Yes. Compressed C-RAW and full CR3 files are both developed.
Will the colours match the camera's JPG?
Closely, not exactly. The camera's white balance is used, but its Picture Style and lens corrections are not part of the raw data.
What does "the camera's own preview" mean?
For a camera too new for the RAW library, the full-size JPG stored inside the CR3 is returned in place of a development, and the result says so.
Is the EXIF data kept?
By default the JPG is written without metadata. The editor's metadata setting decides what is kept from files that carry it through.
Can I convert CR2 files as well?
Yes, on the CR2 to JPG page. The same reader handles CRW, CR2 and CR3.
