CR3 Image Conversion: Batch Convert, Resize & Organize
CR3 is Canon current RAW image format, introduced with the EOS M50 in 2018. It is based on the ISO Base Media File Format (ISOBMFF) and replaces the older CR2 format. CR3 files contain unprocessed sensor data at 14-bit depth, preserving maximum detail for post-processing.
Contenta Converter PREMIUM lets you open, convert, and batch process CR3 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.

| 說明 | CR3 is Canon current RAW image format, introduced with the EOS M50 in 2018. It is based on the ISO Base Media File Format (ISOBMFF) and replaces the older CR2 format. CR3 files contain unprocessed sensor data at 14-bit depth, preserving maximum detail for post-processing. | 差不多所有數碼相機都會有把圖像保存為JPEG的選項。JPEG格式支持每色8位（紅，綠，藍），文件大小也比較小。只要不使用重度壓縮，圖像質量不會受太大的影響。不過JPEG文件如果不斷被修改，保存的話，很有可能會退化。若您計劃以後修改照片圖像，或不能接受圖像失真，把它們保存為非JPEG的無損圖像格式的話會比較好。話雖如此，JPEG大致上是最適合網絡發佈的格式。 |
| 優點 | Supports both uncompressed RAW and compressed C-RAW (roughly 40% smaller files with minimal quality loss). Based on a modern container format that allows embedded previews and faster thumbnail generation. | 小的文件大小，非常受歡迎 |
| 缺點 | Requires updated software to open. Older versions of Photoshop, Lightroom, and other editors may not support CR3 without updates. Not backwards-compatible with CR2 workflows. | 質量損失 |
| 相機 | Canon EOS R, EOS R3, EOS R5, EOS R5 II, EOS R6, EOS R6 II, EOS R7, EOS R8, EOS R10, EOS R50, EOS R100, EOS M50, EOS M50 II, EOS M6 II, EOS 1D X III, EOS 850D, EOS 90D, PowerShot G5 X II, PowerShot G7 X III | |
| 元數據 | Full EXIF metadata including lens data, GPS coordinates, and shooting parameters. Supports XMP sidecar files for non-destructive edits. | 處理XMP, EXIF 或 IPTC |
