What happens when you convert TIFF to PAM?
HDR to SDR
HDR is rendered to SDR using exposure and Reinhard tone mapping.
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 can choose the source image or part needed for delivery.
- You need an SDR delivery copy and can review its tone mapping.
- 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 need the original HDR range for relighting or grading.
- You assume format-level alpha support guarantees matching transparent edges.
- You expect lossless encoding to restore lost details or editing structure.
TIFF to PAM conversion details
- Multiple source images
- One page is converted (default: page 1). Choose another page in Advanced options.
- HDR to SDR
- HDR is rendered to SDR using exposure and Reinhard tone mapping.
- 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
- TIFF: Depends on variant → PAM: Uncompressed TIFF: TIFF is not intrinsically lossless or uncompressed. Read the Compression, BitsPerSample and SampleFormat tags; decoder support varies across schemes. 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
- TIFF: Tagged sample types → PAM: maxval up to 65535
- Multiple images
- TIFF: Image directories
- 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
Will every source image be exported?
One page is converted (default: page 1). Choose another page in Advanced options.
How will HDR brightness be mapped?
HDR is rendered to SDR using exposure and Reinhard tone mapping.
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.
