CR2 to JPG Converter

A CR2 to JPG converter turns a Canon RAW photo into a JPG you can open, share and upload anywhere. This one does it by extracting the JPEG preview your camera embedded inside the CR2 file when you took the shot. It is not a new development of the RAW sensor data: there is no white balance, exposure, highlight recovery or noise reduction step, and the JPG looks like the photo on the back of the camera, with the Picture Style and white balance that were set at the time.

CR2 is the RAW format Canon used for years across its EOS DSLRs, from the 5D Mark II and 7D through to the 5D Mark IV. Newer Canon bodies write CR3, which this page does not read. A RAW file stores what the sensor recorded before processing, typically at 12 or 14 bits per channel, so photo viewers, upload forms and office software often refuse it or show nothing more than a thumbnail.

Canon DSLRs usually store the preview at the full image size, so a 5D Mark IV file gives you a 6720x4480 JPG. Some older or smaller models store a reduced one. The note under each converted file's row says the JPG is the embedded preview, and when the preview is smaller than the full image it prints both sizes, so you always know what you got. When full resolution, a different white balance or recovered highlights matter, open the CR2 in a RAW developer such as darktable, RawTherapee, Lightroom or Canon Digital Photo Professional instead.

The preview is decoded and saved again as a JPG at the Quality setting, which runs from 10 to 100 and starts at 90. Moving the slider converts every added file again at the new setting, so you can compare sizes without adding the files a second time. Portrait shots are turned upright using the orientation recorded in the file. EXIF data, including the capture date, camera settings and any GPS position, is not copied into the new file.

Everything runs client-side. The preview extractor is a small script that loads when you add the first CR2, and the CR2 is read by your browser and never uploaded. Files over 200 MB and previews over 100 megapixels are refused with a message instead of freezing the tab, and a file that is not a CR2 is turned away with a link to the converter that handles it. Add a batch, download the JPGs one by one or as a ZIP. The tool is free, no signup, with a daily limit on conversions.

• The CR2 is read and the preview is saved as a JPG inside your browser tab. The photo is never uploaded.
• The daily limit check sends the tool name, a device identifier and your sign-in token if you have one. It carries no image data.
• After a batch, the page logs the number of files, their total size in bytes and the output format. File names, camera details and pixels are not sent.
• EXIF data, including GPS coordinates and camera details, is left out of the JPG, so the converted file reveals less than the CR2 does.
• Converted JPGs stay in the tab's memory until you remove them, press Clear All or close the page. Nothing is kept on a server.
