Description🔵 Let's be real: an EPUB is just a website masquerading as a book. While a PDF is a rigid digital fossil that refuses to move, the EPUB is 'reflowable.' It actually gives a damn about what device you’re using, reshuffling the text to look just as good on a tiny phone screen as it does on a massive tablet. Since the 3.2 update, it’s been running on a backbone of HTML5 and CSS3, which is why it can finally handle tricky stuff like vertical Japanese scripts or embedded video without breaking a sweat.
Technical details🔵 If you’re curious enough to swap the .epub extension to .zip, you’ll see the 'guts' of the whole operation. It’s not one single file; it’s a packed container full of XML metadata, CSS stylesheets, and content files. This web-based DNA is exactly why it’s the gold standard for accessibility—unlike a flat image, screen readers can actually make sense of the text.
The format also leans on SVG for graphics, ensuring that illustrations don't turn into a pixelated mess when you zoom in. Sure, you’ll often run into DRM locks on retail books, but the format itself is an open, evolving beast. The best part? It’s backward compatible. You can take an old-school EPUB 2 file and throw it onto a modern e-reader, and it’ll still work perfectly. It’s that mix of universal support and 'under-the-hood' simplicity that makes it the undisputed king of digital reading.
It’s also surprisingly flexible with graphics, using SVG to keep illustrations sharp regardless of how much you zoom in. Even though retailers often slap a layer of DRM on top to lock things down, the underlying engine remains an open, evolving standard. Whether it’s an old EPUB 2 file running on a legacy e-reader or a modern multimedia-heavy book on Apple Books, the format’s backward compatibility is what keeps the digital publishing industry from falling apart.

Description🔵 The MOBI (Mobipocket e-book format) is a digital book format, developed by the French company Mobipocket SA. It was specifically designed for low-bandwidth mobile phones. The format works with the Open eBook standard, which is built on XHTML, and can incorporate JavaScript and frames. E-book readers, especially Kindle devices, predominantly utilize the MOBI format.
Technical details🔵 JavaScript can be used to format Mobi files. Additional content such as pages, notes, and drawings can be included in these files. The Mobipocket Reader has a built-in dictionary feature. There is a restriction of 64K on images, which may not be ideal for larger devices like desktops and laptops, but this limitation is more suited to smaller devices like mobile phones. Mobi files bear a resemblance to the Amazon Kindle format, but do not possess the same Java capabilities as the Kindle format. The Open eBook standard, to clarify, is a standard for the representation of digital books and publications, based on XHTML.
