About formats

TIFF (Tagged Image File Format) is a flexible raster image format originally developed by Aldus Corporation (later acquired by Adobe) in October 1986 for desktop publishing and scanning applications. The format uses a tagged data structure where the image file header points to one or more Image File Directories (IFDs), each containing a set of tags that describe the image's dimensions, color space, compression, resolution, and other properties. This extensible architecture means TIFF can accommodate virtually any image type: 1-bit bilevel, grayscale, indexed color, RGB, CMYK, CIE L*a*b*, and beyond, at any bit depth from 1 to 64 bits per sample. TIFF supports multiple compression methods including none (uncompressed), LZW, DEFLATE, JPEG, and CCITT Group 3/4 fax compression, as well as multi-page documents, tiled storage for efficient random access to large images, and floating-point pixel values for HDR content. One advantage is professional-grade flexibility — TIFF handles the full range of image types encountered in publishing, prepress, medical imaging, geospatial analysis, and scientific research, where specialized color spaces and high bit depths are required. Lossless archival quality is another core strength: TIFF with no compression or LZW/DEFLATE preserves every pixel value exactly, making it the standard archival format for libraries, museums, and any institution that requires guaranteed long-term image fidelity. TIFF is supported by every major image editing, scanning, and publishing application across all platforms.

PDB (Palm Database) is a generic database container format created by Palm, Inc. for the Palm OS platform, first appearing with the original PalmPilot in March 1996. In the ebook context, PDB files most commonly use the PalmDOC or Plucker encoding to store readable text with basic formatting. The format consists of a 78-byte header identifying the database name, creation date, and record count, followed by a record index table and the data records themselves. PalmDOC-encoded PDB files use a simple LZ77-based compression scheme to pack plain text efficiently, while Plucker extends this with HTML rendering, image support, and hyperlink navigation. PDB ebooks powered a thriving mobile reading ecosystem years before dedicated e-readers existed — millions of Palm OS users carried entire libraries on devices like the Palm V, Tungsten, and Treo handhelds. A primary advantage is extreme simplicity: the flat record structure and minimal overhead mean PDB files parse instantly even on severely constrained hardware with limited memory and processing power. The open, well-documented structure is another strength, having spawned numerous reader applications across Palm OS, Windows, and later mobile platforms. Though the Palm platform is long discontinued, PDB ebooks remain accessible through conversion tools and readers like Calibre, and the format holds historical significance as one of the earliest practical mobile ebook solutions.
