What happens when you convert PDF to BMP?
Encoding mode
BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. The output uses the implemented still-image encoder; file size depends on the pixels and format.

Portable Document Format
Compression: Depends on variantTransparency: YesMetadata: Document information, XMP, ICC output intents
A fixed-page document format mixing text, vectors and raster images. Image conversion requires deliberate page rendering.

Target
BMP
Windows Bitmap
Compression: Depends on variantTransparency: YesMetadata: DIB header, ICC (V5)
Windows raster storage with several DIB header versions. Simple uncompressed pixels are common, but alpha and compression vary.

Good choice when
- BMP fits your delivery use: Windows bitmap interchange.
- You need a raster preview of a document page.
- You need a transparency-capable destination and will check its supported variant.
- Your receiving application supports the required BMP variant.
Probably not when
- Selectable text, vector objects or document navigation must remain.
- You assume format-level alpha support guarantees matching transparent edges.
- You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.
- You require identical samples without a defined colour and precision policy.
PDF to BMP conversion details
- Page rendering
- One page is converted (default: page 1). Choose another page in Advanced options.
- Transparency representation
- The implemented target supports alpha. Display-pixel processing can round translucent samples; archival sample equality is not promised.
- Encoding mode
- BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. The output uses the implemented still-image encoder; file size depends on the pixels and format.
- Sample precision & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Metadata & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Compression
- PDF: Depends on variant → BMP: Depends on variant PDF: PDF has no single compression quality. Different streams may use lossless or lossy filters; page rasterization can remove document structure even when the resulting pixels are encoded losslessly. BMP: BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Colour depth
- BMP: 1 / 4 / 8 / 16 / 24 / 32 bpp
- Multiple images

- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Is PDF conversion the same as image extraction?

Which compression mode will BMP use?
BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. The output uses the implemented still-image encoder; file size depends on the pixels and format.
Are bit depth and colour values guaranteed to match?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Will metadata and colour profiles be retained?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
