PGM does not support alpha transparency. Transparent TIFF areas must be flattened onto a background color.
Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting TIFF to PGM decodes the source image and writes a PGM output. Use this route when PGM is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on PGM compression: uncompressed.
Choose conversion targets based on PGM compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: Exif, XMP, ICC, IPTC, custom tags.
Supported by ImageMagick, Netpbm, and technical imaging tools.
