Supports: CR3
CR3 is Canon's modern RAW image format, introduced with the EOS R mirrorless camera system. It replaced the older CR2 format and uses the ISOBMFF container (the same container structure as MP4 video). CR3 files contain unprocessed sensor data with full dynamic range and color depth.
| Camera | Resolution | CR3 File Size |
|---|---|---|
| EOS R5 | 45MP | ~50MB (RAW), ~25MB (C-RAW) |
| EOS R6 Mark II | 24.2MP | ~25MB (RAW), ~13MB (C-RAW) |
| EOS R7 | 32.5MP | ~35MB (RAW), ~18MB (C-RAW) |
| EOS R8 | 24.2MP | ~25MB (RAW), ~13MB (C-RAW) |
| EOS R10 | 24.2MP | ~25MB (RAW), ~13MB (C-RAW) |
| EOS R50 | 24.2MP | ~25MB (RAW), ~13MB (C-RAW) |
| EOS R100 | 24.1MP | ~25MB (RAW) |
C-RAW (Compact RAW) is Canon's compressed RAW option — roughly half the file size with minimal quality difference.
CR3 files can't be opened in web browsers, messaging apps, or social media. JPG is universally supported everywhere.
A 45MP CR3 from an EOS R5 is ~50MB. The same image as a high-quality JPG is ~8-12MB — 75-85% smaller.
Convert a batch of CR3 files to JPG for quick review without importing into Lightroom or Canon's Digital Photo Professional.
Yes. Completely free with no watermarks, no sign-up required, and no file count limits.
JPG uses lossy compression, so there's some quality reduction compared to the RAW data. At 90%+ quality settings, the difference is imperceptible for sharing and web use. For professional editing, keep the original CR3 files.
Yes. Both standard CR3 and C-RAW (compressed RAW) files are supported.
Yes. Upload an entire photo shoot and convert all files with the same settings.
