CRW vs BMP Format Comparison
| Aspect | CRW (Source Format) | BMP (Target Format) |
|---|---|---|
| Format Overview |
CRW
Canon PowerShot RAW
Canon's original RAW image format used by early Canon PowerShot and EOS digital cameras. CRW stores unprocessed sensor data with CIFF (Camera Image File Format) container structure, predating the more modern CR2 format. Lossless RAW |
BMP
Windows Bitmap
Uncompressed raster image format native to Windows operating systems. Simple pixel-by-pixel storage without compression, resulting in large file sizes but perfect quality preservation. Lossless Standard |

Why Convert CRW to BMP?
Converting CRW (Canon PowerShot RAW) files to BMP format enables you to access and share your legacy Canon digital camera photos without requiring specialized RAW processing software. CRW is Canon's original RAW format, used in cameras from 2000 to 2004 including the popular PowerShot G series and early EOS DSLRs like the D30, D60, 10D, and 300D (Digital Rebel).
The CRW format uses Canon's proprietary CIFF (Camera Image File Format) container to store unprocessed 12-bit sensor data. While this provides maximum editing flexibility in RAW processors, it requires specialized software like Adobe Camera Raw, Lightroom, or Canon's Digital Photo Professional to view and edit. Converting to BMP makes your images accessible on any device and compatible with standard image workflows.
The BMP format provides specialized capabilities that makes it suitable for specific use cases and targeted applications.
Many photographers and enthusiasts have archives of CRW files from early Canon digital cameras — some of the first consumer digital cameras that shot RAW. Converting these files to BMP preserves these valuable photographic memories in a widely supported format, ensuring they remain accessible for years to come.
Key Benefits of Converting CRW to BMP:
- Accessibility: View images without RAW processing software
- Compatibility: Compatible with BMP-supporting applications and workflows
- Preservation: Safeguard legacy Canon photos in a modern format
- Sharing: Share with colleagues using standard image viewers
- Storage: Organized in a standard, widely-supported format
- Quality: Excellent quality preserved from 12-bit RAW source
- Future-Proof: BMP format will remain supported long-term
Practical Examples
Example 1: Photo Archive to BMP
Input CRW file:
Legacy Canon PowerShot RAW photos (2001-2004). Camera: PowerShot G-series, EOS D30/D60/10D Format: CRW (CIFF container) Resolution: 2-8 megapixels Color depth: 12-bit RAW sensor data
Output BMP file:
BMP-format output files: ✓ Converted from legacy CRW format ✓ Compatible with BMP-supporting applications ✓ Quality preserved during conversion ✓ Ready for target workflow integration ✓ Accessible without RAW processing software ✓ Suitable for distribution and sharing
Example 2: Batch Processing CRW to BMP
Input CRW file:
Bulk collection of Canon CRW files. Mixed cameras: PowerShot G1-G6, Pro1, EOS 10D Total files: 500+ CRW images Storage: external archive drive
Output BMP file:
Batch-converted BMP files: ✓ All files converted consistently ✓ Original filenames preserved ✓ Uniform output format for organization ✓ Reduced dependency on RAW software ✓ Easier to browse and manage ✓ Compatible with standard viewers
Example 3: Legacy Camera Archive to BMP
Input CRW file:
Canon EOS 300D (Digital Rebel) photos (2003). Original format: CRW RAW Resolution: 3072×2048 (6.3 MP) Historical significance: first consumer DSLR
Output BMP file:
Preserved as BMP format: ✓ Accessible without Canon RAW software ✓ Viewable on modern systems ✓ Quality maintained from original ✓ Long-term format stability ✓ Easy to share and distribute ✓ Compatible with modern workflows
Frequently Asked Questions (FAQ)
Q: What is CRW format?
A: CRW is Canon's original RAW image format, used by early Canon PowerShot (G1-G6, Pro1) and EOS (D30, D60, 10D, 300D) digital cameras from 2000 to 2004. It uses the CIFF (Camera Image File Format) container to store unprocessed 12-bit sensor data. CRW was superseded by CR2 (TIFF-based container) starting with the EOS 20D in 2004.
Q: Will I lose quality converting CRW to BMP?
A: No, the conversion preserves all image data without any quality loss. The lossless format maintains every pixel exactly as processed from the CRW source.
Q: What cameras produce CRW files?
A: CRW files were produced by Canon PowerShot G1 (2000), G2 (2001), G3 (2002), G5 (2003), G6 (2004), Pro1 (2004), and EOS D30 (2000), D60 (2002), 10D (2003), and 300D/Digital Rebel (2003). These were among the first consumer digital cameras to offer RAW shooting capability.
Q: What's the difference between CRW and CR2?
A: CRW uses the older CIFF container format (2000-2004), while CR2 uses a TIFF-based container introduced with the EOS 20D in 2004. CR2 offers higher bit depth (14-bit vs 12-bit), better metadata support, and more flexible structure. CR2 was later replaced by CR3 (ISO BMFF container) in 2018.
Q: Is converting CRW to BMP free?
A: Yes! Our online converter transforms CRW files to BMP completely free with no registration, no watermarks, and no file count limits. Simply upload your CRW file and download the converted BMP.
Q: Can I batch convert multiple CRW files?
A: Yes, you can upload and convert multiple CRW files to BMP simultaneously. Our converter handles batch processing efficiently, making it easy to convert entire photo archives from early Canon cameras.
Q: Is CRW format still supported by modern software?
A: Yes, despite being a legacy format, CRW is still supported by Adobe Camera Raw, Lightroom, Canon Digital Photo Professional, RawTherapee, darktable, and other major RAW processing applications. However, converting to BMP ensures your images are accessible without specialized software.
Q: Can I convert CRW to BMP on mobile?
A: Yes, our web-based converter works on all devices including smartphones and tablets. Simply open the page in your mobile browser, upload the CRW file, and download the converted BMP image.
