CR3 to JPG converter
A free CR3 to JPG converter that also writes PNG and WebP, entirely in your browser. CR3 is what every Canon since the EOS R and the M50 writes, and it opens in even less software than CR2 did. This lifts out the full-size JPEG the camera already put inside the file and converts that — with the CR3 never leaving your machine.

JPG has no transparency, so transparent areas become white. Converted files don’t keep EXIF or color profile data.

How to convert a CR3
- Add your CR3 filesDrag them in or browse for them. A CR3 runs to tens of megabytes, and every one of them is read on your machine.
- Keep JPG, or pick PNG or WebPJPG is preselected for a shot from an EOS R or M-series body. PNG keeps the extracted image lossless; WebP makes it smallest.
- Convert and downloadEach CR3 is read by a reader of its own, which loads only when you drop one, and the full-size JPEG inside is re-encoded. A single file saves directly; a card's worth comes back as one ZIP.
Questions about converting CR3
The full-size one. A CR3 carries a smaller Canon preview — 1620 × 1080 on both bodies tested — and a full-size JPEG stored as a one-frame track inside the file. The converter takes the full-size image, keeps the smaller one only as a fallback, and does not develop the raw data itself.
On the two bodies this was measured against, yes: an EOS M50 file came out at 3408 × 2272 and an EOS R6 file at 6000 × 4000, each matching the size the file states for its own raw image. A CR3 whose largest embedded image is only a thumbnail fails that row and says so, rather than handing you something upscaled.
Because they are not the same kind of file underneath. A CR2 is a TIFF, a layout decades of software already reads; a CR3 is built on the ISO box structure that MP4 uses, so anything taught to read a CR2 has to be taught again from scratch. That is why this tool needed a second reader for it — and why the CR2 page and this one look alike and are not.
One file is free. Four hundred, on brand, in every size, is what we do.
