About formats

CRW is Canon's first-generation RAW image format, based on the Camera Image File Format (CIFF) specification developed jointly by Canon, Kodak, and other imaging companies in the late 1990s. Used by Canon's consumer and prosumer cameras from approximately 1998 through the early 2000s — including the PowerShot G-series, EOS D30, EOS D60, and EOS 10D — CRW files store the unprocessed 12-bit sensor readout in a heap-based container structure that differs fundamentally from the TIFF-derived approach used by most other camera manufacturers. The CIFF container organizes data into a hierarchical directory of heap entries, each identified by type and tag, containing the raw image data, JPEG thumbnail, EXIF information, and Canon's proprietary metadata including White Balance tables and Picture Style parameters. CRW was eventually replaced by the CR2 format starting with the EOS-1D Mark II in 2004, as Canon moved to a TIFF-based container that aligned more closely with industry conventions and supported higher bit depths. One advantage of CRW files is historical completeness: they preserve the full original sensor data from an important transitional period in digital photography, and the 12-bit captures from cameras like the EOS D30 still produce excellent results when reprocessed with modern RAW converters. Broad legacy support is another strength — despite its age, CRW remains readable by Adobe Lightroom, Photoshop, RawTherapee, and other modern converters, ensuring these early digital negatives remain accessible.
Developer: Canon
Initial release: 1998
RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.

Frequently Asked Questions

What are the reasons to convert CRW to RGB?

CRW captures Canon's original RAW data in an aging format — transformation to RGB migrates your classic digital photos into a modern, widely supported standard.

What software can open RGB?

Open RGB files using IrfanView, XnView, GIMP, Photoshop, and SGI workstation tools.

Does converting CRW to RGB affect quality?

Your CRW image data is processed carefully during conversion. The resulting RGB retains the maximum quality the target format can support.

How fast is the CRW to RGB conversion?

Speed depends on file size, but most CRW to RGB conversions complete in under a minute. Server-side processing ensures quick turnaround.

Is my CRW file safe during conversion?

Yes — uploaded CRW files are deleted immediately after conversion, and the RGB output is removed from servers within 24 hours for your privacy.

How long are converted files stored?

Your RGB output stays on the server for up to 24 hours. After that, it is permanently removed — so download promptly after conversion.
