Multiple source images
Only one image is decoded; a concatenated image sequence is not exported as a complete set.

What happens when you convert PAM to PDF?
Pixels on a PDF page
Output is a one-page raster PDF at 96 DPI, not an editable vector document.

Good choice when
- PDF fits your delivery use: Fixed-layout documents & print.
- You can choose the source image or part needed for delivery.
- You need a document page for printing or delivery.
- You need a transparency-capable destination and will check its supported variant.
Probably not when
- You require a complete collection, page set or multipart round trip.
- You expect OCR, vector tracing or a smaller image from a PDF wrapper.
- You assume format-level alpha support guarantees matching transparent edges.
- You require identical samples without a defined colour and precision policy.
PAM to PDF conversion details
- Multiple source images
- Only one image is decoded; a concatenated image sequence is not exported as a complete set.
- Pixels on a PDF page
- Output is a one-page raster PDF at 96 DPI, not an editable vector document.
- Transparency representation
- The implemented target supports alpha. Display-pixel processing can round translucent samples; archival sample equality is not promised.
- 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
- PAM: Uncompressed → PDF: Depends on variant 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. 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.
- 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
- Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Common questions
Will every source image be exported?
Only one image is decoded; a concatenated image sequence is not exported as a complete set.
Will PDF turn the image into searchable text or vectors?
Output is a one-page raster PDF at 96 DPI, not an editable vector document.
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.
