Fast, secure CDR to BMP conversion. No registration required.
Opening note — CDR is a raster image format with its own balance of compression, colour depth, and software support. The BMP you want is two clicks away. A CDR → BMP operation is one of the simplest image jobs there is: same pixel grid, different wrapper. What genuinely changes is how lossy the codec is, whether alpha survives, and how large the final file ends up. KaijuConverter picks safe defaults for each of those and lets you override them under Advanced. Technical note: CDR is a raster image format with its own balance of compression, colour depth, and software support. Compare that with BMP is the uncompressed Windows bitmap format — bulky but pixel-perfect.
CorelDRAW
Source formatCDR is the native vector graphics format for CorelDRAW, a popular illustration and graphic design application. It supports multi-page documents, layers, color management, and both vector and bitmap content in a single file.
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.
Why convert CDR to BMP
The real reason to move from CDR to BMP is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking BMP solves those edge cases at the cost of a short conversion step.
HOW TO CONVERT
CDR → BMP
Provide the CDR
Click or drag to upload. We accept a single CDR file per job, with an optional queue of additional images for batch mode.
Encode to BMP
The conversion decodes the CDR, resolves the colour space to sRGB and writes the BMP container around the pixel data.
Save the BMP
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all BMP outputs is produced instead.
Common Use Cases
Share across platforms
Send BMP files to anyone without worrying about whether they have the right software for CDR.
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 CDR 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.
CDR vs BMP — Strengths and limitations
What each format does best, and where it falls short.
CDR Strengths
- Native format for CorelDRAW, an industry standard in signage and prepress.
- Multi-page documents (unlike Illustrator's art boards).
- Strong color management (CMYK, Pantone spot, ICC).
- Large market share in Eastern Europe and niche print industries.
Limitations
- Proprietary, unstable format — versions drift dramatically.
- No Adobe Illustrator interoperability; SVG export is the compatibility path.
- Third-party CDR import support (Inkscape, etc.) is partial.
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
CDR-to-BMP conversion does not change the visible content. Quality is capped by the CDR decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original CDR alongside the BMP copy.
Tips for Best Results
- Large CDR files may look identical to small BMP files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export BMP at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related CDR images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
It depends on the codecs involved. If both CDR 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 CDR exactly, but cannot recover detail that CDR had already compressed away.
Often yes, especially when BMP is lossless. CDR 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.
