BMP vs SVG
Um comparativo detalhado de BMP Image e SVG Vector Image — 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 BMPSVG Vector Image
Raster & Vector ImagesSVG is an XML-based vector image format that scales to any resolution without quality loss. It is the standard for web icons, logos, and illustrations that need to look sharp on all screen sizes.
Sobre os arquivos SVGComparativo 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.
SVG Vantagens
- Resolution-independent — crisp at any size, from 16px icon to 4K billboard.
- Tiny file sizes for flat graphics, logos, and UI illustrations.
- Editable with any text editor; programmatically manipulable via DOM.
- Supports interactivity, CSS styling, and JavaScript inside the image.
- Accessible — text inside SVG is readable by screen readers.
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.
SVG Limitações
- Not suitable for photographs or complex raster imagery.
- Uploading user-provided SVG is risky — embedded scripts are an XSS vector.
- Complex SVGs with thousands of paths render more slowly than a PNG equivalent.
- Inconsistent rendering across browsers for edge-case features (filters, gradients).
- No native concept of layers or groups for design-tool round-tripping.

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.
