About formats

GIF (Graphics Interchange Format) was introduced by CompuServe on June 15, 1987 as a platform-independent image format for transmitting color graphics over the CompuServe online service's modem-speed connections. The format uses LZW (Lempel-Ziv-Welch) lossless compression on indexed-color images with a palette of up to 256 colors selected from a 24-bit RGB color space. GIF's most distinctive capability is animation: multiple image frames can be stored sequentially within a single file, each with independent delay timing, disposal methods, and local color palettes, enabling short looping animations without any video codec or player. The format also supports binary transparency (one palette entry designated as fully transparent) and interlaced display for progressive rendering. GIF became synonymous with web culture — animated GIFs proliferated across early websites, messaging platforms, and social media, evolving into a communication medium in their own right. One advantage is universal animation support — GIF animations play natively in every web browser, email client, messaging app, and social platform without plugins, codecs, or compatibility concerns, a level of ubiquity no other animation format has achieved. The lossless compression on palette-based images provides another strength: graphics with flat colors, text, and sharp edges (logos, diagrams, UI elements) compress efficiently without the artifacts that affect JPEG. Although the LZW patents that once threatened GIF's use expired in 2004, and newer formats like WebP and AVIF offer superior compression with full-color animation, GIF's cultural entrenchment keeps it irreplaceable for casual animated content.

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.
