| 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. |
