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.

PICON (Personal Icon) is a small-format image type used in the X Window System ecosystem, developed by Steve Kinzler at Indiana University around 1990 as part of the picons (personal icons) database project. Picons are small, typically 48x48 pixel, color images used as visual identifiers for people, organizations, domains, and Usenet newsgroups in Unix mail readers, news readers, and other communication tools. The picon format is essentially an XPM (X PixMap) image stored with specific naming conventions and directory structures that allow software to look up the appropriate icon based on email address, domain name, or newsgroup name. The picons database organized thousands of these small images in a hierarchical directory structure keyed by domain name components (e.g., faces/com/example/user.xpm), enabling mail clients like exmstrstrstr and faces to automatically display a sender's photo or organizational logo alongside their messages. The system predated the modern concept of contact photos and avatars by more than a decade. One advantage is the system's pioneering role in visual identity for electronic communication: picons introduced the idea that email and Usenet messages should display a visual representation of the sender — a concept that eventually became standard in every modern email client, messaging app, and social media platform. The XPM-based format ensures that picons are displayable on any system with X Window libraries. Picon images are supported by ImageMagick, GIMP, and X Window display utilities, and the historical picons database remains archived online at Indiana University.

Frequently Asked Questions

Why convert MOBI to PICON?

PICON generates tiny icon-sized images from ebook pages — useful for creating visual identifiers, thumbnails, or catalog previews of your library.

What software opens PICON files?

ImageMagick, XnView, IrfanView, and most Unix-based image viewers handle PICON files natively without any extra configuration needed.

What resolution does PICON produce?

PICON is designed for small icon-sized images. The output captures a miniaturized rendering of your MOBI page content at low resolution.

Is text readable in PICON output?

No — PICON is an icon format with very small dimensions. It is meant for visual identification rather than reading actual ebook text.

Can I convert multiple MOBI files at once?

Yes. Convertio supports batch uploads, so you can queue several MOBI ebooks and convert them all to PICON in a single session.
