CR3 to JPG Converter

Canon cameras released since 2018 save raw photos as CR3, a format that older Photoshop, Lightroom and photo viewers cannot read. Upload the CR3 files here and get full-resolution JPGs you can share, print or send to a client.

How to use this tool

  1. 1

    Add your CR3 files

    Copy them from the SD card or the Canon app and drop up to 20 onto the uploader. Each file can be up to 95 MB, which covers every current Canon raw.

  2. 2

    Keep quality at 92

    Quality starts at 92 for full-resolution prints. Lower it, or set Resize output image to a longest side of 2048 px under Advanced settings, if the JPGs are for sharing.

  3. 3

    Convert to JPG

    Press Convert to JPG. Each raw becomes one JPG, upright and in sRGB; download them one by one or as a ZIP.

Why your software won't open Canon CR3 files

Canon replaced its long-running CR2 format with CR3 in 2018. CR2 was built on the TIFF structure that raw tools had read for years; CR3 uses the ISO base media file format, the same container family as MP4 and HEIF, and a new compression scheme often called CRX. Software written before 2018 does not recognize either part, so it reports an unknown file or shows only a tiny embedded preview.

Even current software needs an update per camera. Each new body, from the EOS M50 to the R5, R6 and R100, adds raw details that editors learn through updates, so a perpetual-license copy of Photoshop or Lightroom stops opening CR3 from the cameras released after its final update. Converting to JPG removes that dependency for viewing and sharing. For the older Canon format, see CR2 to JPG.

CR3

Canon Raw 3

Canon Raw 3 (CR3) is the raw image format written by Canon cameras. Canon introduced it in 2018 and it is used by current EOS R mirrorless cameras; it is based on the ISO media container and offers an optional smaller, lossy C-RAW mode. Older software that reads CR2 may not read CR3. A raw file stores the sensor data before the camera applies white balance, sharpening and compression, which leaves far more room to recover highlights, shadows and colour when editing. Files are large and cannot be shared directly on websites, social networks or most phones. Lightroom, Capture One, darktable and the manufacturer's own software open them, but plain image viewers often show only a small embedded preview or nothing at all.

JPG

JPEG image

JPEG (or JPG) is the most widely used photo format, standardised by the Joint Photographic Experts Group in 1992. It uses lossy compression that discards fine detail the eye is unlikely to notice, which keeps photos small enough for the web, email and phone storage. It handles smooth gradients and natural scenes well, but sharp text, line art and flat colours pick up visible blocky or fuzzy artefacts. JPEG has no transparency and no animation, and every re-save loses a little more quality. Every browser, phone, camera and image editor can open it.

JPG converter

People convert CR3 to JPG because Canon's newer raw format will not open in older editors, phones, web galleries or client inboxes, while a JPG of the same shot opens everywhere at once.

Convert CR3 to JPG: what the converter decides for you

A raw file is not a picture yet; it is sensor data that has to be developed. The converter uses the white balance recorded by the camera, applies a neutral tone curve, rotates the image using the orientation flag and maps colors to sRGB so the JPG looks right on phones and the web. Dual Pixel data and Canon's in-camera lens corrections are not applied.

If you shot in a high-contrast scene and need recovered highlights or shadows, edit the CR3 in a raw editor first and export from there. For straightforward sets, such as an event gallery or images a client wants to preview today, a direct conversion at quality 92 is fast and faithful. Need smaller files for email? Run the results through compress image afterwards.

CR3 to JPG questions

Why can't Photoshop open my CR3 files?

CR3 support needs Adobe Camera Raw from 2018 or later, plus a version new enough to know your specific camera. Photoshop CS6 and the standalone Lightroom 6, whose last update came in December 2017, will never read CR3. Converting to JPG, or to DNG with Adobe's free DNG Converter, gets the photo into older software.

Will the JPG look the same as the picture on my camera screen?

Close, but not identical. The camera preview is a JPG rendered with your Canon Picture Style, while a raw decoder applies its own neutral tone curve to the sensor data. Expect slightly flatter contrast or different saturation; Canon's free Digital Photo Professional reproduces Picture Styles exactly if you need that look.

What is the difference between CR3 RAW and C-RAW?

Both are CR3 files. RAW uses lossless compression, while C-RAW applies light lossy compression to make files noticeably smaller and speed up bursts. Both convert the same way, and in a JPG the difference is not visible at normal viewing sizes.

How do I open CR3 files on Windows 10 or 11?

Install Microsoft's free Raw Image Extension from the Microsoft Store; after that, Photos and File Explorer show CR3 thumbnails and previews. It does not convert files, so you still need a converter when someone else must open the photo.

Does converting CR3 to JPG keep the camera settings in EXIF?

Strip metadata is on by default, so GPS location, serial number and lens data are removed from the JPG before sharing. Turn it off under Advanced settings to keep the shutter speed, aperture, ISO and capture date in the file.

Is JPG the right output for editing later?

No. A JPG has 8 bits per channel and baked-in white balance, so heavy edits show banding sooner. Keep the CR3 as the master and edit it in a raw editor; convert to JPG only for the finished, shareable copy. Other brands work the same way on raw to JPG.
