CR2是由佳能数码相机创建的原始图像文件，用Photoshop和Lightroom进行处理和编辑。它是专业摄影师使用的一种高质量、无压缩的格式。
CR2格式是当前数字内容世界中的一个多媒体标准。而它显示了以下的优点和缺点。
不是任何应用程序都能打开CR2文件，因为它很少被使用。用户可以选择使用微软相机编解码包或安装佳能RAW编解码软件。虽然CR2文件也可以用IrFanView和CanvasX等免费程序打开。但是，在打开和编辑这些文件方面，Adobe Photoshop是最受欢迎的。
CR2是一种基于TIFF规格的格式，不允许图像质量有任何损失。CR3使用旧的规格，如CIFF，这允许文件更小，但图像分辨率更低。如果你想保留你的图像质量，CR2可能是最好的选择。
虽然CR2和Raw图像相似，但它们并不一样。CR2格式是佳能相机独有的，而RAW图像可以来自任何扩展或来源。
CR2文件的大小只能通过在你的编辑中删除像素或进行有损压缩来减少。

CR2 format guide
CR2 is Canon’s older TIFF-based camera RAW format with sensor data and a preview.
Published still-image routes use the deployed ImageMagick and Ghostscript toolchain, with dedicated workflows for animation, camera RAW rendering, SVG tracing, and selected modern formats where the generic path is not sufficient.
TIFF is appropriate for high-quality editing handoff; JPG makes a smaller review copy.
The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.
PNG and TIFF are useful lossless working targets. JPG is lossy and removes transparency; WebP and AVIF may be lossy or lossless. Preserve source pixel dimensions unless resizing is intentional.
Canon picture styles, lens corrections, and the original sensor mosaic are not preserved in a rendered export.
These links come from the active conversion catalog, not from a generic list of possible formats.
Choose one of these implemented routes; a listed extension is not a promise that every codec variant will decode.
Check that the file opens in its original application, is not encrypted or DRM-protected, and really matches its extension. A damaged header, unsupported internal codec, missing linked asset, or mislabeled file can fail even when CR2 is generally supported. Try a different published target only when it fits your goal; changing the extension by hand does not convert the file.
