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.

PALM is a bitmap image format used by the Palm OS operating system, introduced in 1996 with the original Palm Pilot 1000. Palm bitmap files store raster images in formats optimized for the extremely constrained hardware of early Palm handheld devices — the original models featured a 160x160 pixel monochrome (2-shade) display, 128 KB of RAM, and a 16 MHz Motorola 68328 processor. The format evolved through several versions as Palm hardware improved: PalmOS 1.0 supported 1-bit monochrome, later versions added 2-bit (4 shade grayscale), 4-bit (16 shade), 8-bit (256 color), and eventually 16-bit (65536 color) direct color modes. Palm bitmaps use a simple header specifying width, height, row bytes, flags, and bit depth, followed by the pixel data which may use optional Scanline compression (a PackBits-like run-length encoding) or dense packing. The format also supports bitmap families — multiple versions of the same image at different bit depths bundled together, allowing the OS to select the best version for the current device's display capabilities. One advantage is the format's documentation of early mobile computing: Palm OS was the dominant handheld platform of the late 1990s and early 2000s, and Palm bitmap files from applications, games, and content of that era represent important artifacts of mobile computing history. The multi-depth bitmap family feature provides another notable design strength — a single resource could serve devices ranging from monochrome Palm Pilots to the 16-bit color Sony CLIE and Palm Tungsten. PALM bitmaps are supported by ImageMagick, pilot-link utilities, and Palm emulator tools.

Frequently Asked Questions

Why convert MOBI to PALM?

PALM pixmap is the native image format for Palm OS devices. Converting MOBI pages creates images displayable on Palm handhelds and emulators.

How do I open a PALM file?

Palm OS devices display PALM pixmaps natively. On modern systems, ImageMagick and Palm OS emulators like PHEM can handle the format.

Is PALM the same as PDB?

No — PDB is a Palm database format for ebooks. PALM pixmap is specifically an image format optimized for the Palm OS display hardware.

Are the images optimized for small screens?

Yes. PALM pixmap images are designed for the limited resolution and color depth of Palm OS device screens — compact and efficient.

Can I batch-process a whole ebook?

Yes — Convertio converts every page of your MOBI ebook into PALM images automatically. Download the complete set when processing finishes.
