To batch convert CR3 to JPG, load a whole folder instead of single files, set JPG once, and run the job in one pass. A desktop converter processes the entire shoot using all CPU cores, so 500 files take one queue, not 500 clicks.
Browser converters are the part that falls down here. Most take one file at a time on the free tier, and a full card of 24-megapixel CRAW files is a lot of uploading before you even start. They were built for a quick one-off, not a 600-shot wedding where every CR3 has to be a client-ready JPG by Monday.
A desktop batch tool processes the whole queue in one go. Point Batch Picture Resizer at the folder, set JPG, and it runs the whole shoot at once, with no per-file dialog and no waiting behind an upload. It is a full RAW to JPG converter software, not a Canon-only tool, so Nikon NEF and Sony ARW files go through the same batch. You can also resize during the same pass, setting a pixel size or a target file size in KB, which saves a second run when the JPGs are headed for a web gallery.
What is a CR3 file, and which Canon cameras use it?
CR3 is Canon's RAW image format introduced with the DIGIC 8 processor. It stores unprocessed sensor data and uses an ISO Base Media File Format container with Canon's "crx" codec, which is why older software that only knew CR2 cannot read it.
CR3 arrived on the EOS M50 in 2018 and is now standard on Canon mirrorless bodies like the EOS R5, R6, R8, and R50, plus many PowerShot models. Canon also offers a smaller "C-RAW" variant inside the same CR3 wrapper to cut file size, so a single shoot can mix full CR3 and C-RAW files. If you just moved from a CR2-era DSLR to an EOS R body, that container swap is exactly why your old converter suddenly rejects the files: the photos look the same, but the format underneath changed.
That container change, documented on the Wikipedia raw image format page, is why any program not updated for the crx codec reports the file as unsupported or damaged. The fix is either an updated app or a converter that already speaks CR3.
CR3 vs JPG: which should you keep?
Keep CR3 when you still plan to edit, because it holds far more color and dynamic range for recovery. Convert to JPG when you need to share or send files that open anywhere. Many photographers archive the CR3 and hand out JPGs.
A CR3 file carries 14-bit sensor data with room to push exposure and white balance later. A JPG is 8-bit and lossy: the converter bakes in your settings and discards data to shrink the file. That trade is fine for delivery and terrible for heavy editing. The practical workflow is to keep the RAW originals and batch out JPGs for everything that leaves your drive.
| Feature | CR3 | JPG |
|---|---|---|
| Data | 14-bit RAW sensor data | 8-bit, lossy compression |
| File size | Larger (20-90 MB) | Smaller (2-8 MB) |
| Editing room | Wide; recover highlights and redo white balance | Narrow; settings are baked in |
| Opens anywhere | Needs RAW support / a converter | Yes, on almost any device |
| Best for | Editing and archiving | Sharing, print, email |
Does converting CR3 to JPG keep your EXIF data?
Yes. A good CR3 to JPG converter copies the EXIF metadata into the JPG by default - camera model, lens, exposure settings, the capture date, GPS location if it was recorded. You usually get an option to strip metadata on purpose, for example before posting photos publicly.
EXIF survives the conversion unless you turn it off. Batch Picture Resizer carries metadata over and also reads the orientation flag, so portrait shots come out upright instead of sideways. If you are sharing images and would rather not publish your location, strip GPS or all metadata during export. That is a deliberate choice, not a side effect. Same goes for the CR2 generation if you are still shooting an older body; the CR2 to JPG converter path handles those the same way.
Why does the converted JPG look flat or washed out?
A flat JPG usually means the RAW was converted without the camera's color profile or white balance. RAW looks neutral by design; the in-camera preview applies a picture style. Set white balance and a bit of contrast before export, or use a converter that applies sensible defaults.
The camera shows you a processed JPG preview on its screen, even when it saved a RAW file. So the CR3 usually looks more contrasty on the back of the camera than the "real" RAW data does. When a converter dumps the raw values straight to JPG with no adjustments, the result can look dull or slightly off compared to what you remember. Two fixes help here. Set white balance and basic contrast during conversion, and avoid converters that ignore the embedded profile. For a whole batch, lock in one white balance and apply it across the shoot so the JPGs stay consistent.
