About formats

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.

PCT (also known as PICT) is a metafile graphics format originally developed by Apple Computer and introduced alongside the original Macintosh in January 1984. PCT files can contain both vector drawing commands and raster bitmap data, encoded as a sequence of QuickDraw drawing operations — the same graphics primitives used by the Macintosh operating system for all on-screen rendering. The format evolved through two major versions: PICT 1, which recorded basic QuickDraw operations (lines, rectangles, ovals, text, 1-bit bitmaps) in a compact format suitable for the original Macintosh's limited memory, and PICT 2, introduced with Color QuickDraw in 1987, which extended the format to support 24-bit color, multiple color spaces, and embedded JPEG-compressed data. PCT files begin with a 512-byte header (originally used for resource fork information), followed by the picture size, bounding rectangle, and a sequence of opcodes that define the drawing operations. During the Macintosh's commercial ascendancy, PICT was the universal graphics interchange format on Mac OS — the system clipboard used PICT for all graphical copy/paste operations, and most Mac applications could import and export the format. One advantage is the hybrid vector/raster nature: PCT files from the QuickDraw era preserve both scalable drawing commands and pixel data in a single format, enabling resolution-independent output for the vector portions. PICT's historical significance as the native Mac graphics format throughout the classic Mac OS era (1984-2001) provides another dimension. PCT files remain readable by Preview on macOS, ImageMagick, XnView, LibreOffice, and GIMP.

Frequently Asked Questions

Why convert MOBI to PCT?

PCT (PICT) was the native image format for classic Mac OS. Converting MOBI pages to PCT is necessary for legacy Apple workflows and vintage Mac systems.

How do I open a PCT file?

macOS Preview can open PCT files. On other platforms, IrfanView, XnView, and ImageMagick handle the PICT format for viewing and conversion.

Is PCT the same as PICT?

Yes — PCT is an alternative file extension for the Apple PICT format. Both refer to the same image format developed by Apple for Macintosh.

Does modern macOS fully support PCT?

Preview on macOS still opens PCT files, but Apple has long deprecated PICT in favor of PNG, JPEG, and HEIC for modern workflows.

Can I use PCT in current design projects?

For current projects, PNG or SVG are better choices. PCT is primarily useful when working with legacy Mac files or vintage Apple systems.
