HOW TO CONVERT CR3 → BMP
Upload your CR3
Start by dropping the CR3 onto the uploader. Files up to 25 MB go through on the free tier without registration; paid plans go up to 2 GB.
Conversion happens server-side
Our imagemagick-based pipeline reads the CR3 pixel grid, preserves resolution and colour profile, and encodes a clean BMP.

CR3 is Canon's newer RAW format used across modern EOS cameras. Reaching a BMP from there is one hop. Need a BMP for a CMS, a chat message or an email client that politely refuses CR3? This tool re-encodes your image in the background and returns a drop-in BMP replacement. No registration, no watermark, no visual change beyond what the BMP encoder itself introduces. One more beat. CR3 is Canon's newer RAW format used across modern EOS cameras. Receiving format: BMP is the uncompressed Windows bitmap format — bulky but pixel-perfect.
Why convert CR3 to BMP
Converting keeps the picture recognisable end-to-end while changing the container that ships it. BMP typically wins on one of three fronts: broader software support, smaller files for the same visual quality, or features like transparency that CR3 cannot express. The conversion itself is fast because both sides are raster formats.

CR3 vs BMP — Strengths and limitations
What each format does best, and where it falls short.
CR3 Strengths
- Modern ISO Base Media File Format container.
- Supports lossless + compressed C-RAW in the same extension.
- Preserves every pixel of Canon mirrorless sensors.
- Compatible with Canon's cross-camera pipeline (DPP, Cinema EOS).
Limitations
- Proprietary — no public spec.
- Third-party support is always playing catch-up with each new body.
- Older Canon processing software (DPP 4) does not read CR3.
BMP Strengths
- Dead-simple format — trivially easy to read and write.
- Lossless and uncompressed — perfect bit-exact pixel storage.
- Universally supported in Windows applications since 1985.
- Supports 1, 4, 8, 16, 24, and 32-bit color depths.
Limitations
- Enormous file sizes — no meaningful compression in typical use.
- Not a web format — browsers support it but nobody serves BMPs over HTTP.
- No metadata support (no EXIF, no ICC profile in practice).
Quality & Compatibility
Converting keeps resolution, aspect ratio and colour profile identical to the source. Metadata (EXIF, XMP) transfers where BMP supports it; otherwise it is dropped. If the CR3 contained an alpha channel and BMP does not support transparency, the background is flattened to white by default.
Tips for Best Results
- When uploading to Retina / high-DPI contexts, render the BMP at 2× the CSS pixel size; the crispness gap over 1× is noticeable on modern screens.
- Strip EXIF metadata from the BMP before publishing if the CR3 came from a phone camera — it often contains GPS coordinates and device IDs.
- If the CR3 is a screenshot of text or UI, prefer a lossless BMP target to avoid the JPEG-style ringing around glyph edges.
Frequently Asked Questions
It depends on the codecs involved. If both CR3 and BMP are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If BMP is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded CR3 exactly, but cannot recover detail that CR3 had already compressed away.
Often yes, especially when BMP is lossless. CR3 tuned for efficient web delivery will usually produce smaller files than BMP's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
Canon RAW CR3
Source formatCR3 is the newer Canon RAW format used in EOS R mirrorless cameras and newer DSLRs. It offers improved compression and image quality over CR2.
BMP Image
Target formatBMP is an uncompressed raster image format native to Windows. Files are large but preserve exact pixel data with no compression artifacts. Rarely used on the web due to file size.
Common Use Cases
Share across platforms
Send BMP files to anyone without worrying about whether they have the right software for CR3.
Embed in documents
Drop BMP output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
BMP often produces smaller files than CR3 for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
