toolkit Drop as many Canon CR3 files as you like above to convert them to JPG right here, in this browser tab, with the whole batch returned as one .zip. Decoding runs entirely on your own device and nothing is uploaded, so a shoot under NDA can be converted without breaking it.
What CR3 is
CR3 is Canon's current raw image format, used by its more recent camera bodies as the successor to CR2. It's a different container than CR2, which is why it gets its own decode path and its own page here.
Whole shoots, not one file at a time
A batch here is a queue you can watch and steer. Files convert in the order you added them, each showing its own progress; you can cancel one that is running, drop the rest of the queue in a single click, or retry anything that failed, all without disturbing the photos that already converted. That control is the reason batches run one file at a time rather than all at once. However many you add, it is free.
Why convert it
A CR3 keeps far more of the sensor's original data than a JPEG, which is why photo editors want it — but most viewers, messaging apps, and websites can't open it directly. Converting to JPG gives you something you can view, share, or upload anywhere.
Orientation is preserved
The camera's orientation tag stored in the CR3 is read and applied before the pixels are returned, so the output JPG comes out the right way up rather than needing a manual rotate.
Quality control
You can set the output JPEG quality before converting. Since a CR3 starts with substantially more detail than a JPEG, a higher quality setting is worth considering if file size isn't a concern.
Frequently asked questions
Is my photo uploaded anywhere?
No. Decoding and JPG encoding both happen locally in your browser via WebAssembly; the CR3 file never leaves your device.
Can I convert a batch of CR3 files?
Yes, with no limit on how many. They convert in the order you added them and each one has its own progress, cancel and retry, so a single awkward file never costs you the rest of the batch. The finished photos are offered as one .zip.
Is CR3 the same format as CR2?
No — CR3 is a different, newer container. Use the dedicated CR2 to JPG page if your file is a .CR2 instead.
Will orientation be correct?
Yes — the CR3's own orientation tag is read and applied automatically before conversion.
Can I convert a JPG back into CR3?
No. CR3 decoding is one-way here — there's no encoder that writes CR3 files.
Does this apply Canon's in-camera picture style or any edits?
No. This performs a straightforward decode of the raw sensor data in the file — camera picture styles and post-capture edits made in a separate editor aren't applied here.
