BMP vs CDR
Um comparativo detalhado de BMP Image e CorelDRAW — tamanho de arquivo, qualidade, compatibilidade e qual escolher de acordo com seu fluxo de trabalho.
BMP Image
Raster & Vector ImagesBMP 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.
Sobre os arquivos BMPCorelDRAW
Raster & Vector ImagesCDR 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.
Sobre os arquivos CDRComparativo de vantagens
BMP Vantagens
- 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.
CDR Vantagens
- 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.
Limitações
BMP Limitações
- 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).
- Multiple header versions mean "a BMP" is ambiguous — parsers must handle several variants.
CDR Limitações
- 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.
- File sizes balloon quickly with embedded photos.

BMP (Bitmap) is a raster image format developed by Microsoft for Windows. It stores images with no compression by default, resulting in large file sizes but pixel-perfect quality. It has been part of Windows since version 1.0.

PNG is better than BMP in almost every scenario since it provides lossless compression (smaller files), transparency support, and wider cross-platform use. BMP is mainly relevant for legacy Windows applications.
