How to Convert Canon CR2 or CR3 RAW Files to JPG
Yes. The tool reads CR2 (older bodies) and CR3 (newer bodies like the EOS R series) RAW files directly, decoding them on-device and converting to JPG, WebP, or AVIF.
CR2 and CR3 are two different containers
CR2 is the RAW format used by Canon's older bodies (5D III, 60D, and other earlier EOS DSLRs). CR3 is the newer container adopted after 2018 (EOS R series, 90D, 850D, and similar), with better compression efficiency but weaker support in some older viewer software. Both are read directly by the tool without first converting to DNG in another app.
Decoding and compression in one step
The conventional workflow is two steps: export the RAW to JPG in viewer software, then compress the result with another tool. This merges both steps — the browser reads RAW pixel data directly and applies your chosen compression while encoding to the target format.
| Output format | Best for |
|---|---|
| JPG | Messaging, email attachments, opens in virtually any app |
| WebP | Smaller than JPG at the same quality, supported by every major browser |
| AVIF | Smallest files, but a few older devices or apps may not open it |
Batch-processing a full shoot
A single shoot is often dozens or hundreds of CR2/CR3 files. Drop the whole folder in for batch processing and download a ZIP when it finishes. For long batches, test settings on three to five representative photos first — including backlit shots and dark shadow detail — before committing the whole set.
- Keep the tab open and prevent the computer from sleeping during a long batch.
- Always keep a separate backup of the originals; save compressed output under new filenames.
- Spot-check tricky lighting conditions individually rather than trusting batch defaults for everything.
