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
MTV is a simple raster image format created by Mark T. VandeWettering for the MTV Ray Tracer, a ray tracing program released in 1988 as one of the early publicly available ray tracers distributed through Usenet. The format stores 24-bit RGB images with a minimal text header followed by raw pixel data. The header consists of a single line containing the image width and height as ASCII integers, followed immediately by the pixel data where each pixel occupies three bytes (red, green, blue) arranged in row-major order from top-left to bottom-right. The MTV Ray Tracer itself was significant in the history of computer graphics — distributed freely via the comp.graphics Usenet newsgroup, it introduced many programmers and students to the principles of ray tracing: ray-object intersection, reflection, refraction, shadows, and recursive shading. The MTV format was the program's native output, and its simplicity made it easy for users to write custom viewers and converters on whatever platform they had access to — a practical necessity in the fragmented Unix workstation landscape of the late 1980s. One advantage is extreme implementation simplicity: the format can be read in a handful of lines of code in any programming language, with no libraries, no compression algorithms, and no metadata parsing required — just read two integers and then read width x height x 3 bytes of pixel data. The format's historical significance in the computer graphics community provides another dimension — MTV files from early ray tracing experiments represent primary artifacts from the era when ray tracing transitioned from academic research to accessible software. MTV files are supported by ImageMagick and various legacy graphics tools.

Frequently Asked Questions

Why convert CRW to MTV?

CRW is Canon's legacy RAW format that modern software increasingly drops support for — converting to MTV future-proofs your older Canon photo library.

Which apps support MTV?

You can open MTV with MTV raytracer, IrfanView, and XnView.

Does converting CRW to MTV affect quality?

The conversion preserves visual quality as closely as the target format allows. MTV output maintains the essential detail from your original CRW image.

Is my CRW file safe during conversion?

Your files are handled securely. The CRW upload is erased right after processing, and the resulting MTV is purged from servers within 24 hours.

Can I convert multiple CRW files to MTV at once?

Absolutely — Convertio lets you upload multiple CRW files simultaneously. Each is converted to MTV and available for individual download.

How fast is the CRW to MTV conversion?

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