What happens when you convert PDF to PAM?
Lossless sample storage
Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PAM can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.

Good choice when
- PAM fits your delivery use: Channel-aware image pipelines.
- You need a raster preview of a document page.
- You need a transparency-capable destination and will check its supported variant.
- You need lossless storage of the rendered samples supported by PAM.
Probably not when
- Selectable text, vector objects or document navigation must remain.
- You assume format-level alpha support guarantees matching transparent edges.
- You expect lossless encoding to restore lost details or editing structure.
- You require identical samples without a defined colour and precision policy.
PDF to PAM 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.
- Lossless sample storage
- Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PAM can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.
- 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 → PAM: Uncompressed 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. PAM: Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Colour depth
- PAM: maxval up to 65535
- Multiple images
- PDF: Page tree
- Vector graphics
- PDF: Paths & text on pages
- Dimensions
- One page is converted (default: page 1). Choose another page in Advanced options.
- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Common questions
Is PDF conversion the same as image extraction?

Does lossless output mean an unchanged source?
Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PAM can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.
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.
