What is a .cr3 file?
CR3 is Canon's current raw format, introduced with the EOS M50 in 2018 and used across the R-series mirrorless range. It compresses better than the older CR2 and adds C-RAW, a lossy mode that roughly halves file size — though it took editing software a while to catch up when it launched.
What people use CR3 files for
- Originals from a Canon R5, R6 or recent EOS body
- Raw deliverables for commercial and wedding work
- Files handed to a retoucher for processing
- Archives kept before editing
What opens a CR3 file
- Lightroom and Camera Raw, from late 2018 onward
- Canon Digital Photo Professional, free from Canon
- Capture One and recent darktable versions
- Older software may not recognise CR3 at all
How to host a CR3 file
- 1
Drop your CR3 file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.

Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: canon-raw.99helpers.site

Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.
The same three steps work for any file — see how file hosting works on 99helpers.com.
What happens when someone opens the link
The file downloads and opens in a raw editor. Software from before 2019 often can't read CR3, which is the main practical difference from the older CR2.
Why host a CR3 file instead of emailing it?
Raw delivery is standard in commercial photography and the files are far too large to email. A permanent link per file beats a transfer service that expires while the client is still deciding what to do with them.
Worth knowing before you publish
- C-RAW roughly halves file size with very little visible cost, and is often the difference between fitting under the 25 MB limit and not.
- If a recipient can't open your CR3, their software predates the format — converting to DNG solves it immediately.
- Host a JPEG alongside so the client can see the shot without a raw editor.
CR3 hosting questions
- What's the difference between CR2 and CR3?
- CR3 is newer, compresses better and adds the C-RAW lossy option. CR2 is more universally supported because it has been around far longer — software from before 2019 often can't read CR3.
- Why won't my editor open a CR3 file?
- It predates the format. Update the software, use Canon's free Digital Photo Professional, or convert to DNG with Adobe's free converter, which any raw editor can read.
- Is C-RAW worth using?
- For most work, yes — roughly half the file size with differences that are hard to see. For maximum-quality commercial work, stick to full raw.
