Convert Typst to MOBI

Why Convert Typst to MOBI?

Converting Typst to MOBI brings your typeset documents into the Amazon Kindle ecosystem, the world's most popular e-book platform. MOBI format is natively supported by all Kindle devices and Kindle reading applications on iOS, Android, PC, and Mac. By converting your Typst documents to MOBI, you create e-books that can be read comfortably on Kindle's e-ink displays or sent directly to Kindle devices via Amazon's Send-to-Kindle feature.

This conversion is particularly valuable for authors and educators who create content in Typst and want to distribute it as e-books. Course materials, textbooks, tutorials, and technical guides written in Typst can be converted to MOBI for students to read on their Kindle devices. The reflowable text format ensures comfortable reading on screens of all sizes, with adjustable font sizes and reading progress tracking.

For self-publishing authors using Typst for manuscript preparation, MOBI conversion is a key step in the publishing workflow. While Amazon's Kindle Direct Publishing (KDP) now prefers EPUB or KPF formats, MOBI remains widely used for personal distribution and sideloading to Kindle devices. The conversion preserves chapter structure, formatting, and metadata while adapting the content for optimal e-book reading.

The converter processes Typst source to extract content structure, text formatting, and metadata, then packages it into a MOBI file with proper chapter navigation and table of contents. While complex Typst features like advanced math and precise page layouts are simplified for the reflowable e-book format, the textual content and document organization are faithfully preserved.

Key Benefits of Converting Typst to MOBI:

• Kindle Reading: Read your Typst documents on any Kindle device or app
• Reflowable Text: Content adapts to any screen size with adjustable fonts
• Chapter Navigation: Automatic chapter-based table of contents
• Send-to-Kindle: Email MOBI files directly to your Kindle device
• Offline Reading: No internet connection needed once downloaded
• Self-Publishing: Create e-books from Typst manuscripts for distribution
• Compact Size: MOBI compression produces small, portable files

Practical Examples

Example 1: Technical Book for Kindle

Input Typst file (book.typ):

#set document(
  title: "Learn Rust Programming",
  author: "Alex Johnson",
)

= Chapter 1: Introduction
== Why Rust?
*Rust* is a systems programming language
that guarantees _memory safety_ without
a garbage collector.

== Getting Started
Install Rust using rustup:
```
curl --proto '=https' --tlsv1.2
  -sSf https://sh.rustup.rs | sh
```

= Chapter 2: Basics
== Variables
#let example = "let x = 5;"
Use `let` to declare variables:
`#example`

Output MOBI file (book.mobi):

Kindle-ready e-book with:
✓ Chapter-based navigation
✓ Table of contents
✓ Reflowable text content
✓ Code blocks preserved
✓ Bold and italic formatting
✓ Adjustable font size
✓ Kindle bookmark support

Example 2: Course Notes for Students

Input Typst file (notes.typ):

= Physics 101: Mechanics
== Newton's Laws
=== First Law
An object at rest stays at rest unless
acted upon by an external *force*.

=== Second Law
$ F = m a $
Force equals mass times acceleration.

=== Third Law
For every _action_, there is an equal
and opposite _reaction_.

== Practice Problems
+ Calculate the force on a 5 kg object
  accelerating at 3 m/s^2
+ Determine the acceleration of a
  10 kg object with 50 N applied

Output MOBI file (notes.mobi):

Student-friendly e-book:
✓ Clear chapter structure
✓ Newton's laws with formatting
✓ Practice problems as numbered list
✓ Readable on Kindle or phone
✓ Offline study material
✓ Highlighting and notes support
✓ Progress tracking

Example 3: Personal Writing Collection

Input Typst file (essays.typ):

#set document(
  title: "Collected Essays",
  author: "Maria Garcia",
)

= The Future of Cities
Modern cities face challenges of
*sustainability* and _livability_.

== Smart Infrastructure
Technology transforms how we build
and manage urban spaces.

= Digital Minimalism
In an age of constant connectivity,
*intentional technology use* becomes
essential for well-being.

Output MOBI file (essays.mobi):

Personal e-book collection:
✓ Each essay as a chapter
✓ Author and title metadata
✓ Table of contents navigation
✓ Comfortable reading layout
✓ Send to Kindle via email
✓ Syncs across Kindle devices
✓ Personal library addition

Frequently Asked Questions (FAQ)

Q: Can I read the MOBI file on my Kindle?

A: Yes! MOBI is natively supported by all Amazon Kindle devices, from the original Kindle to the latest Kindle Scribe. You can transfer the file via USB, email it using Amazon's Send-to-Kindle feature, or use the Kindle app on iOS, Android, PC, or Mac.

Q: How are Typst math equations handled in MOBI?

A: MOBI has limited mathematical typesetting support. Simple equations are rendered as text, while complex equations may be converted to images embedded in the e-book. For math-heavy documents, consider converting to PDF instead, which preserves mathematical notation perfectly. The text content surrounding equations is always preserved.

Q: Is MOBI or EPUB better for e-books?

A: EPUB is the open standard supported by most e-readers (Kobo, Nook, Apple Books), while MOBI is specific to the Amazon Kindle ecosystem. If you target Kindle readers, MOBI works directly. For broader distribution, EPUB is more versatile. Amazon's KDP now accepts EPUB for publishing, making EPUB increasingly preferable.

Q: Are Typst tables preserved in MOBI?

A: Tables are converted to HTML tables within the MOBI file. Simple tables with text content display well on Kindle devices. However, complex tables with many columns may not render optimally on smaller Kindle screens due to the reflowable nature of e-book content. Consider simplifying tables for the best e-book reading experience.

Q: Can I publish the MOBI on Amazon KDP?

A: While Amazon Kindle Direct Publishing historically accepted MOBI files, Amazon now recommends uploading EPUB or KPF (Kindle Package Format) files for new publications. The MOBI format remains useful for personal distribution and sideloading. For KDP publishing, consider converting your Typst document to EPUB instead.

Q: How does the converter handle Typst chapter structure?

A: Typst's = level-1 headings are treated as chapter breaks in the MOBI file. Each chapter gets an entry in the table of contents. Sub-headings (==, ===) create sections within chapters. This produces a well-organized e-book with proper navigation that readers can browse using the Kindle's Go To menu.

Q: What metadata is preserved in the MOBI?

A: Document metadata set with Typst's #set document() function, including title and author, is embedded in the MOBI file's metadata. This information appears in the Kindle library listing and device catalog. Additional metadata like publication date and language can also be preserved.

Q: What about images in Typst documents?

A: Images included with Typst's #image() function are embedded in the MOBI file. MOBI supports JPEG and GIF images. Large or high-resolution images are automatically resized for optimal display on Kindle screens. SVG and other vector formats are rasterized during conversion.
