Convert CR3 images to BMP instantly in your browser. No upload, no account needed — fully client-side and secure.
WebP typically reduces file size by 25-35% compared to PNG with equivalent visual quality.
Frequently Asked Questions
Is my image data safe?
Absolutely. 100% of the conversion processing occurs inside your local web browser sandbox. No file chunks or metadata are transmitted to our servers or stored anywhere externally.
Will transparency be preserved?
Converting to lossless formats like PNG preserves full transparency (alpha-channel). If you are converting to JPEG, any transparent sections are rendered as solid background colors (customizable in output settings).
Can I convert multiple images at once?
Yes, you can drop or select multiple files simultaneously. Our tool processes and triggers the sequential download of all assets with a single click.
About CR3
What are CR2, CR3, and CRW files? Proprietary RAW image files created by Canon digital cameras. They contain uncompressed, unprocessed sensor data. CRW is the oldest, CR2 is the standard, and CR3 is the newest (supporting compressed RAW).
How to open them? Adobe Lightroom, Photoshop (via Camera Raw), Apple Photos, or Canon's Digital Photo Professional.
Typical use: Professional photography using Canon cameras, allowing maximum flexibility in post-processing (exposure, white balance).
Origin: Developed entirely by Canon.
Modern alternatives: DNG (Digital Negative) is often used to standardize RAW files across different camera brands.
About BMP
What is a BMP file? An uncompressed raster image format. It stores color data for every individual pixel, resulting in extremely high quality but massive file sizes.
How to open a BMP file? Microsoft Paint, Windows Photos, Apple Preview, and almost any image viewer/editor.
Typical use of a BMP file: Historically used as the standard Windows graphic format. Today, it is rarely used outside of legacy software or specific programming environments.
Origin of the BMP file: Developed by Microsoft in the 1980s for the Windows operating system.
Modern alternatives for BMP: PNG provides the exact same lossless quality but with efficient compression, making files a fraction of the size.
