CR2 Image Conversion: Batch Convert, Resize & Organize
A Canon RAW image file. RAW files store sensor data exactly as the camera captured it — before white balance, color correction, or compression are applied. They are the photographer's digital negative: full tonal range, editable later, faithful to what the sensor saw.
Contenta Converter PREMIUM lets you open, convert, and batch process CR2 files into modern formats like JPG, PNG, TIFF, PDF, and more. Optimize file size, keep important metadata, and prepare images for web, print, or long-term archiving in just a few clicks.

| Description | A Canon RAW image file. RAW files store sensor data exactly as the camera captured it — before white balance, color correction, or compression are applied. They are the photographer's digital negative: full tonal range, editable later, faithful to what the sensor saw. | JP2 and J2K are two container formats for the JPEG 2000 image standard, both storing the same wavelet-compressed image data. JP2 adds metadata boxes (EXIF, XMP, ICC color profiles); J2K is just the raw codestream. JPEG 2000 was designed in 2000 as the successor to JPEG, with better compression, lossless mode, and features for medical imaging and archival. |
| Benefits | Nothing is baked in. You keep the full dynamic range (usually 12–14 stops), accurate colors, and the ability to change white balance, exposure, or color profile in post without losing quality. Shoot once, produce multiple interpretations later. | Both lossy and lossless compression in the same format. Progressive decoding — a low-resolution preview appears before the full image finishes loading. Region-of-interest coding lets you specify areas that should stay at higher quality. Used in medical imaging (DICOM), film archiving (DCP digital cinema packages), and geospatial data. |
| Drawbacks | File sizes are 20–40 MB for a 24 MP sensor, versus 5–8 MB for a high-quality JPEG. No web browser, email client, or phone gallery opens them directly — you need a RAW processor to view them. Every camera brand uses its own flavor, and older RAW files sometimes stop being supported as editors move on. | Slow to encode and decode compared to standard JPEG — roughly 5–10× slower. Still not universally supported by web browsers (Safari added support late; Firefox needs a plugin). Outside specialized industries, very little software opens JP2/J2K without conversion. |

What Canon cameras shoot CR2?
CR2 was used by most Canon DSLRs and some PowerShot models from 2004 to 2018, including the EOS 5D series (Mark II, III, IV), EOS 6D, EOS 7D, EOS 80D, EOS Rebel/Kiss series, and EOS-1D X Mark II. Newer Canon cameras (EOS R series) use the CR3 format instead.
What is the difference between CR2 and CR3?
CR2 is Canon older RAW format based on TIFF structure, while CR3 uses the modern ISO Base Media File Format. CR3 supports C-RAW (compressed RAW) for roughly 40% smaller files and faster writing speeds. Both preserve full 14-bit sensor data for editing.
