Exporting a LaTeX file to ePUB and MOBI formats involves several steps and tools. Here's a step-by-step guide to achieve this conversion:

Step 1: Convert LaTeX to HTML

First, you need to convert your LaTeX document into HTML. This can be done using tools like tex4ht or htlatex, which are part of the TeX4ht package. This package converts LaTeX to HTML, handling mathematical equations by converting them to MathML or images.

Using TeX4ht

To use TeX4ht, you can run the following command in your terminal:

This command converts yourfile.tex to HTML with MathML for equations.

Step 2: Convert HTML to ePUB

Once you have the HTML files, you can convert them to ePUB using tools like Calibre or Sigil.

Using Calibre

1. Install Calibre: Download and install Calibre from its official website.

2. Add the HTML File: Open Calibre, click on "Add Books" and select the HTML file generated by TeX4ht.

3. Convert to ePUB: Right-click on the added book and select "Convert books" > "Convert individually". Choose ePUB as the output format.

Using Sigil

1. Install Sigil: Download and install Sigil.

2. Open the HTML File: Open Sigil and import the HTML file.

3. Save as ePUB: Use Sigil to edit and refine the layout if needed, then save the file as an ePUB.

Step 3: Convert ePUB to MOBI

To convert the ePUB file to MOBI, you can use Calibre again.

1. Open Calibre: With the ePUB file already in your Calibre library, right-click on it.

2. Convert to MOBI: Select "Convert books" > "Convert individually". Choose MOBI as the output format.

Alternatively, you can use the ebook-convert command line tool that comes with Calibre:

Alternative Methods

Using Softcover

Softcover is another tool that simplifies the conversion process by handling LaTeX to HTML conversion and then to ePUB. It also supports conversion to MOBI using Calibre's ebook-convert tool.

Using LaTeX2ePub Scripts

The latex2epub scripts provide a workflow for converting LaTeX to Markdown and then to ePUB using Pandoc. This method requires Perl and Pandoc.

Using TeX4ebook

TeX4ebook is a tool specifically designed for converting LaTeX to e-book formats like ePUB and MOBI. It uses TeX4ht for the conversion process.

Each method has its advantages and may require additional steps for fine-tuning the output, especially for documents with complex layouts or mathematical equations.
