CR3 is the raw format of Canon’s current cameras — the EOS R, R5, R6, R7, R8, R10, R50, the M50 and M6 Mark II, and the 90D and 1D X Mark III. Nothing on an ordinary computer opens it, and a portal, a printer or a family chat wants a JPG.
Every CR3 carries a full-size JPEG the camera rendered when the photo was taken, with Canon’s own colour and Picture Style. This page reads that picture from the file on your own device and gives you a JPG at the quality or size you choose — the raw sensor data in a CR3 is not developed yet, and the result card says so.
Nothing is uploaded, and a CR3 opens in a few seconds because there is no development to do.
How to convert Canon CR3 to JPG
Add one CR3 file or a whole batch from the card or the camera app.
JPG is already selected. Set a maximum width or a size limit if the photo is going to a form.
Press Convert. The camera’s full-size JPEG is read out of the file on your device — a few seconds per file, as there is no development to do.
Download the JPG, or a ZIP for a batch.

Where it runs
In your browser; nothing uploaded
Not for: Raw development — the sensor data in a CR3 is not decoded; the camera’s full-size JPEG is used, as the result card says.
Frequently asked questions
Are my files uploaded to a server?
No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.
Is this the raw data or the camera’s JPEG?
The camera’s own full-size JPEG, which Canon stores inside every CR3 at the sensor’s resolution. The compressed sensor data (CRX) is not decoded yet. For most uses — a form, a print, a share — the camera’s JPEG is exactly the picture you wanted; for raw development keep the CR3 for later.
What about C-RAW files?
C-RAW (compressed raw) files are also CR3 and carry the same full-size JPEG, so they convert the same way. The file checked here was a C-RAW from an EOS R6.
Which cameras write CR3?
Canon bodies released from 2018: EOS R, RP, R3, R5, R6 and R6 Mark II, R7, R8, R10, R50, R100, M50 and M50 Mark II, M6 Mark II, 90D, 250D, 850D and 1D X Mark III, and the PowerShot G5 X Mark II and G7 X Mark III.
Is the camera information (EXIF) kept?
No. The JPG is rebuilt from the pixels alone, so camera model, exposure, date and location are not carried over. For a photo you are about to upload to a form or share, that is usually what you want.
Is there a size limit?
A picture is reduced, keeping its proportions, when it is larger than the memory a browser tab can hold: above about 16 megapixels on a phone or tablet, above 60 megapixels on a computer. Anything below that keeps every pixel.
Why does the first file take a moment to open?
The reader for these files is a 3.5 MB engine that is downloaded from this site the first time one of them is opened in a visit, then kept for the rest of the visit. It runs in a background thread of your browser; the file itself is never sent anywhere.
