About formats

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.

SGI is the generic file extension for the Silicon Graphics Image format, also referred to by channel-specific extensions .rgb (3 channels), .rgba (4 channels), .bw (grayscale), and .int/.inta (16-bit variants). Developed by Silicon Graphics around 1986 for their IRIX operating system, the SGI format uses a 512-byte header followed by planar image data, where each color channel is stored as a complete plane rather than interleaved with other channels at each pixel. The header specifies a magic number (474), compression mode (0 for verbatim, 1 for RLE), bytes per channel (1 or 2), dimensionality (1 for scanline, 2 for image, 3 for multi-channel image), channel dimensions, pixel value range, and an 80-character image name. For RLE-compressed images, a table of offsets and lengths follows the header, allowing random access to individual scanlines without sequential decompression. Silicon Graphics workstations were the backbone of Hollywood visual effects, scientific visualization, flight simulation, and CAD/CAM industries throughout the 1990s, and the SGI format was the standard working format across these domains. One advantage is the format's robust design: the combination of scanline-addressable RLE compression, multi-channel support, 16-bit depth capability, and planar layout made it equally suitable for quick preview display and production rendering output. The format's association with the golden age of SGI-powered visual effects is another notable aspect — SGI files from this era represent production assets from landmark films and scientific visualizations. SGI images are supported by ImageMagick, GIMP, XnView, Photoshop (via plugin), and various 3D rendering and compositing applications.

Frequently Asked Questions

Why convert PDB to SGI?

Moving from PDB to SGI gives you Silicon Graphics raster — essential when you need your legacy Palm data in a widely supported format.

What programs open SGI files?

You can open SGI files with ImageMagick, GIMP, IrfanView, XnView. Most platforms have at least one built-in or free option available.

What if my PDB file is corrupted?

The converter validates your file on upload. If the PDB data is unreadable or corrupt, you will get an error before processing begins.

Will I lose image quality converting PDB to SGI?

The conversion preserves the original quality of your PDB file. Any inherent quality limits in PDB carry over, but nothing additional is lost.

Can I convert multiple PDB files to SGI at once?

Yes — upload several PDB files simultaneously and convert them all to SGI in a single batch operation.

Is the PDB to SGI conversion instant?

Processing is fast — most PDB files convert to SGI within a few seconds, depending on image dimensions and server load.
