Convert CRW files online for free
The converter easily converts your CRW file to various formats - free and online. No Adobe Camera Raw or extra software needed.
The converter also works in reverse, so you can convert other Camera Raw formats to CRW with high quality output.
The .CRW file is a legacy raw image format produced by early Canon digital cameras (such as the EOS D30, D60, and original Digital Rebel/300D) from the late 1990s and early 2000s. Unlike modern CR2 or CR3 files which are based on TIFF or ISO standards respectively, .CRW files utilize the obsolete Camera Image File Format (CIFF) structure. These files contain the raw, unprocessed data directly from the camera's sensor, offering maximum dynamic range for editing but at the cost of large file sizes and poor compatibility.
Working with .CRW files today presents significant friction. Because the format has been deprecated for nearly two decades, modern operating systems and image viewers often lack native support. A critical quirk of the .CRW format is its frequent dependency on a companion THM (thumbnail) file; without this sidecar file, you may lose essential EXIF metadata (like exposure settings and date taken) during processing. Furthermore, you cannot upload .CRW files directly to the web, social media, or most print services.
To modernize your photo archive, immediate conversion is recommended. For archival purposes, converting to the open standard DNG (Digital Negative) ensures long-term readability without relying on proprietary Canon drivers. For editing in software like Adobe Photoshop, converting to 16-bit TIFF preserves color fidelity. For quick sharing or web viewing, convert your .CRW files to JPG or WebP. You can use convert.guru to handle these legacy conversions efficiently, ensuring your old digital memories remain accessible.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CRW converter.
