About formats

PES is a machine embroidery file format developed by Brother Industries, used primarily with Brother and Babylock home and semi-professional embroidery machines. The format stores complete embroidery designs including stitch coordinates, color sequence information, and design metadata within a structured binary file. Unlike the minimalist DST format, PES files embed thread color data — specifying both the color sequence and palette references — so the machine displays correct thread colors on its LCD panel without manual configuration. PES version numbers have evolved alongside Brother's PE-Design digitizing software, with each release supporting additional machine features like larger hoop sizes, more color stops, and enhanced stitch types. The format handles standard stitch movements, jump stitches, trim commands, and color change markers, with coordinate precision suitable for detailed reproduction. One advantage is embedded color information — when a PES file loads on a compatible machine, it displays the complete color sequence and thread recommendations, streamlining setup. The tight integration with Brother's PE-Design software is another strength, providing a complete workflow from design creation through machine embroidery output with auto-digitizing, lettering tools, and stitch simulation. PES is among the most popular formats in the home embroidery community, supported by major digitizing software and widely available through online design marketplaces.

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.
