About the CRW file format
Canon RAW (Legacy) (CRW) is a camera RAW format that retains image data captured by a digital camera. RAW files are normally converted to a standard image format before sharing or publishing.
On jpg.now, the format guide and converter lists below are generated from the same live converter catalog. That means every conversion shown here is an available workflow involving CRW files.
Why CRW files are used
Canon RAW (Legacy) is a camera-oriented RAW format used to retain image data captured by a sensor before a final photograph is rendered.
RAW files provide editing latitude for exposure, white balance and colour, but they normally need to be developed in compatible software before everyday viewing or sharing.
What to know about CRW
Camera-origin data
CRW is intended as a source for photographic development rather than a finished delivery image.
Editing latitude
RAW workflows usually preserve more tonal and colour information than an already-rendered delivery file.
Rendering required
A RAW processor interprets sensor data, camera settings and colour information to produce a viewable image.
Metadata-rich
Camera model, capture settings, timestamps and other photographic metadata may accompany the image data.
Larger source files
RAW files prioritize retained capture information and are commonly larger than delivery-oriented JPG images.
Software-dependent
Support can depend on the exact camera model, codec version and RAW engine used by the application.
How CRW conversion works
Converting CRW requires developing the RAW capture into rendered pixels, then encoding those pixels in the destination format. Default processing choices influence colour, tone and sharpness.
The converted image is suitable for viewing and sharing, but it is not a replacement for the original RAW capture when future editing flexibility matters.
jpg.now currently accepts CRW as a source format and converts it to supported outputs. This page lists 1 available conversion involving the format.
CRW compatibility and software support
RAW compatibility depends on the camera, file variant and decoder. Professional photo applications tend to support more RAW formats than browsers, messaging apps and basic image viewers.
A JPG output is broadly compatible and convenient for delivery. Keep the CRW source if you may revisit exposure, colour or other development decisions.
Before deleting or replacing a source file, confirm that the converted format preserves the visual quality and features required by the receiving application.

What changes when a CRW file is converted?
Converting CRW requires developing the RAW capture into rendered pixels, then encoding those pixels in the destination format. Default processing choices influence colour, tone and sharpness.
Should I keep the original CRW file?
Yes, when the file matters. A converted copy can be easier to use, but it may not retain every capability, editing feature or piece of metadata available in the original CRW file.
