Canon CR3 to PNG

CR3 is the RAW format Canon introduced in 2018, starting with the EOS M50. It stores data from the camera sensor for maximum editing flexibility, but browsers, many image viewers and design programs cannot open it. Each CR3 also contains a full-size JPEG the camera rendered at capture. This tool extracts that image and saves it as a PNG, a format everything can open, so you can view and share your shots without RAW software.

Click the file area or drag your CR3 files onto it; only .cr3 files are accepted. They appear in the Conversion Queue with their sizes. Click Convert to PNG, and each file shows Processing and then Done as its PNG downloads automatically under the same name. A file that cannot be read is marked Error and the rest continue. Click Clear All to empty the queue. Your browser may ask once for permission to download several files.

PNG is lossless, so saving the camera's image as PNG adds no second round of JPEG compression, which helps if you plan to retouch the file and re-save it several times. The source, however, is the JPEG the camera already rendered, so PNG cannot add detail, bit depth or dynamic range beyond what that image holds. PNG files are much larger than JPEGs. For viewing, emailing and posting online, a high-quality JPEG is usually the more practical choice.

CR2 and CR3 are both proprietary raw image formats developed by Canon, but CR3 is the newer generation. Introduced in 2018, the CR3 format uses a different internal file structure based on the ISO Base Media File Format. The most significant difference is that CR3 introduces a Compressed Raw option. This provides a lossy compression method that significantly reduces file size while maintaining image quality that is virtually indistinguishable from uncompressed raw files for most practical purposes. CR2 does not offer this space-saving compression feature, making CR3 a more efficient choice for photographers shooting high volumes of images.

PNG uses lossless compression, so it stores every pixel of the full-size image exactly and discards nothing to save space. Photographs are full of fine variation that lossless compression cannot shrink much, so a PNG of a high-resolution photo can be many times larger than a JPEG of the same picture, and often larger than the CR3 itself. That is normal. If storage space or web loading speed matters and you do not need a lossless file, a high-quality JPEG is the practical alternative.

Always keep your original raw files for archiving and editing, because they hold the full sensor data for exposure and color corrections. Converting to PNG makes sense when an image needs to be viewed or shared somewhere that does not support raw formats: sending proofs to clients, adding images to a document or presentation, or checking shots on a computer without RAW software. Because PNG is lossless, it is also a safe intermediate if you will retouch the camera's rendering and re-save it several times.

No fixed limit. The conversion runs on your own device, so nothing is transferred and there is no connection to time out. CR3 files from high-megapixel cameras can exceed 40 or 50 megabytes, and the tool handles them, but each file has to be read into your browser's memory. On an older computer or phone, very large batches can slow things down, so convert fewer files at a time and close other heavy tabs if the page becomes sluggish.

Yes. Your CR3 images are processed entirely within your web browser, on your own device, so they never leave it, there is no transfer to intercept and there is no stored copy to delete afterward. Your new PNG files are saved directly to your computer, and you keep full ownership of every photograph. The first time, you confirm you're a photographer and create or log into a free Imagen account, which unlocks this tool and every other one on the site.

Yes. Select or drop as many CR3 files as you like, and add more before you start. The tool converts them one after another and downloads each PNG separately as it finishes; there is no ZIP file. It is designed for quick conversions of a selection of images. For developing hundreds of RAW files with your own edits applied, a desktop RAW editor is the better tool, since it renders from the sensor data rather than from the camera's preview.

No. The PNG is saved from the image pixels only, so camera model, lens, aperture, shutter speed, ISO, capture date, GPS and copyright details are not carried over. The image is turned upright before saving, so it does not depend on an orientation tag. If your workflow relies on metadata for cataloging or credit, keep the original CR3 files alongside the PNGs, or export from your RAW software with metadata included when it needs to travel with the image.
