HOW TO CONVERT RAW → BMP
Drop the RAW file
Drag and drop or click to upload your RAW. The image is transferred securely over HTTPS and queued for conversion.
Re-encode with ImageMagick
ImageMagick decodes every pixel of the RAW and writes a matching BMP with sensible default quality settings.
Download the BMP
The converted BMP is ready to download as a single file; both files delete automatically within two hours.
Setup: RAW captures sensor data directly from a digital camera with no in-camera processing. Goal: an interchangeable BMP. Converting RAW to BMP swaps one image container for another without leaving the image family. The choice usually comes down to compatibility with the tool or platform that will consume the file next — some editors handle BMP natively while RAW still requires a plugin or extra step. KaijuConverter re-encodes in the browser session with ImageMagick, preserving resolution and colour profile, and leaves the source RAW untouched. Background. RAW captures sensor data directly from a digital camera with no in-camera processing. Destination side, BMP is the uncompressed Windows bitmap format — bulky but pixel-perfect.
Why convert RAW to BMP
Both RAW and BMP describe a grid of pixels — the difference lies in how that grid is compressed, whether transparency is supported, and which software opens it natively. Moving from RAW to BMP is worth it when the BMP ecosystem is broader for your use case, or when BMP compresses photographs more efficiently than RAW.

RAW vs BMP — Strengths and limitations
What each format does best, and where it falls short.
RAW Strengths
- Every bit of sensor data preserved for post-processing latitude.
- Higher bit depth (12-16 bits) than JPEG (8-bit) — smoother gradients.
- Non-destructive editing in raw processors.
- Rich metadata (EXIF, makernotes, camera settings).
Limitations
- Proprietary per brand — Canon CR2 will not open in a pure-Canon-free processor.
- Huge files compared to JPEG.
- Requires dedicated software (Lightroom, Capture One, Darktable, etc.).
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
If BMP is a lossless format (PNG, TIFF, BMP) the output keeps every pixel of the decoded RAW exactly. If BMP is a lossy codec (JPEG, WebP, HEIC), the encoder re-compresses the image at the quality level you select — default 85 is transparent for photographs, quality 92+ for illustrations with hard edges.
Tips for Best Results
- Keep the original RAW alongside the BMP output — re-encoding already-lossy images accumulates detail loss on each round.
- If the BMP will be uploaded to a CMS, check whether the platform has a max dimension and downscale once on export rather than letting the CMS resize automatically.
- For thumbnails and avatars, export the BMP at exactly the display size; browsers will otherwise resample and the image may look soft.
Frequently Asked Questions
It depends on the codecs involved. If both RAW 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 RAW exactly, but cannot recover detail that RAW had already compressed away.
Often yes, especially when BMP is lossless. RAW 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.
Generic RAW Image
Source formatRAW is a generic term for files containing minimally processed data from a camera image sensor. Various camera manufacturers use proprietary RAW variants, but the term broadly refers to any unprocessed sensor capture that retains maximum editing flexibility.
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 RAW.
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 RAW 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.
