CR2 vs BMP: Format Comparison

Key differences between the two formats

Feature	CR2	BMP
Type	RAW camera file (Canon)	Raster image
Bit depth	12-14 bit per channel	8-bit
Compression	Minimal (sensor data)	None
File size	20-60 MB typical	50-80 MB
Editing flexibility	Full (white balance, exposure)	Limited (pixels fixed)
Software support	Canon software, Lightroom, etc.	Universal
Web display	Not supported	All browsers
Color profile	Camera-native	sRGB (converted)

When to Convert

Common scenarios where this conversion is useful

Sharing Canon photos without RAW software

Not everyone has Lightroom or Capture One. Converting your CR2 files to BMP lets anyone view and use your photos with standard image viewers and web browsers.

Legacy system compatibility

Some older software, hardware, or institutional systems only accept BMP format. Converting from CR2 ensures compatibility with these requirements.

Specific workflow integration

When a downstream process or tool requires BMP input, converting directly from CR2 saves an intermediate step compared to processing in RAW software first.

Who Uses This Conversion

Tailored guidance for different workflows

Professional Photographers

Convert CR2 selects to BMP for quick client delivery without full RAW processing
Batch convert Canon files for web gallery uploads and portfolio updates

Keep your original CR2 files — the converted BMP cannot be converted back to RAW quality

Use dedicated RAW software (Lightroom, Capture One) when you need creative control over exposure and color

Photography Enthusiasts

Convert Canon photos to BMP for sharing with friends and family
Transform CR2 shots to BMP when you don't need full RAW editing

Check the converted BMP on your target display (phone, monitor) to verify colors look correct

Consider JPG for sharing and PNG for editing if BMP isn't the best fit

Digital Asset Managers

Convert CR2 archives to BMP for universal access across teams
Create BMP derivatives from Canon originals for DAM system previews

Maintain the CR2 originals as master files and use BMP for distribution

Use the authenticated API for automated batch conversion workflows

How to Convert CR2 to BMP

1

Upload your CR2 file

Drag and drop your Canon RAW file into the converter or click to browse. Files are uploaded with TLS encryption.
2

RAW processing

Our server processes your CR2 file using dcraw with automatic white balance, demosaicing, and color correction, then converts to BMP format.
3

Download your BMP

Save your converted BMP image. Your original CR2 file is automatically deleted from our servers.

Frequently Asked Questions

Does converting CR2 to BMP lose quality?

Some quality reduction is inherent when converting from RAW to any standard format. RAW files contain 12-14 bits of color data per channel, while BMP uses 8 bits. However, dcraw applies professional white balance and color processing to produce high-quality output. The result looks excellent for sharing, printing, and web use.

What about white balance and exposure adjustments?

dcraw automatically applies the camera's recorded white balance settings. Unlike Lightroom or Capture One, you can't manually adjust exposure or color temperature before conversion. If you need creative control over RAW processing, use dedicated RAW software first.

Can I batch convert multiple CR2 files?

The web interface handles one file at a time. For batch processing, use the authenticated API (/v1/convert) which supports programmatic access for automated workflows.

Is the conversion secure?

Your CR2 file is uploaded via encrypted TLS, processed on our servers using dcraw, and automatically deleted immediately after conversion. We never store, view, or analyze your photos.

What's the maximum file size?

The web converter accepts files up to 25MB (free tier; 500MB on Pro), which covers most CR2 files. High-resolution cameras may produce larger RAW files — the authenticated API supports up to 500MB.

Why would I convert CR2 to BMP?

BMP is rarely needed for photography. The main use case is legacy software or hardware that only accepts BMP input — some older printing systems, embedded displays, or industrial applications. For general photography, JPG, PNG, or TIFF are better choices.

How large will the BMP be?

Very large. BMP stores uncompressed pixel data. A 24-megapixel CR2 produces roughly a 70MB BMP file. Make sure you have sufficient storage and bandwidth before converting.

Can I compress the BMP?

BMP files are uncompressed by design. If you need a smaller file, convert to PNG (lossless, much smaller) or JPG (lossy, dramatically smaller) instead.
