Haddock to LaTeX Converter
Processing entirely on your device — large files may take a moment.
Haddock Documentation and LaTeX Source exist for different jobs: Haddock is the documentation markup of the Haskell ecosystem: -- comment blocks attached to functions, rendered into the API docs every Hackage package ships. Convert Markdown, Word or EPUB content to LaTeX when the destination is arXiv, a journal submission or a thesis template.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How Haddock compares to LaTeX
| Haddock | LaTeX | |
|---|---|---|
| Structure | Comment markup (--, 'links', @mono@) | Macro markup language |
| Best for | Haskell API documentation | Papers, theses, preprints |

About the Haddock format
Haddock is how Haskell explains itself: documentation comments in -- blocks, marked up with 'links' to identifiers, @monospace@ and /italics/, compiled into the API reference pages every package on Hackage publishes. The markup lives inside source files, but the format is its own small language.
Converted out of source comments, Haddock text becomes ordinary structured prose: Pandoc maps headings, code blocks and identifier links onto Markdown or HTML, so API knowledge can move into handbooks, wikis or static-site generators without retyping.
+Strengths
- ✓Documents live next to the code they describe
- ✓Identifier-aware linking across the API
- ✓Standard for the entire Haskell ecosystem
!Limitations
- −Meaningful only inside Haskell projects
- −Small grammar, few writers outside Haddock itself
- −Embedded in comments — needs extraction first
About the LaTeX format
LaTeX is how academia writes: preprints, theses, journal submissions and most of arXiv and Springer's back-catalogue are LaTeX sources. A .tex file is plain text with markup commands — \\section{…}, $math$, \\cite{…} — that a compiler turns into perfectly typeset PDF with numbered equations, cross-references and bibliographies.
Converting into LaTeX is the boring 80% of the academic workflow: your Markdown notes, Word draft or EPUB becomes a .tex skeleton with proper sectioning and math, ready to paste into the journal's template. The output here is source, not a compiled PDF — the final typesetting happens in the journal's or arXiv's own compiler.
+Strengths
- ✓The required format for arXiv and most journals
- ✓Math, cross-references and citations as first-class citizens
- ✓Plain text — version-controllable and diff-able
!Limitations
- −Not directly viewable — needs a LaTeX compiler
- −Steep learning curve for manual editing
- −Complex layouts may need template tweaks
Why convert Haddock to LaTeX?
Converting makes sense where the strengths of LaTeX meet what Haddock cannot give you. The required format for arXiv and most journals Meanwhile Meaningful only inside Haskell projects One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this Haddock to LaTeX converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for Haddock to LaTeX?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does the conversion work offline?
Yes. Once the page has loaded, the conversion itself runs entirely inside your browser — you can even disconnect and keep converting. No file ever touches a server.
Will the layout of my Haddock file be preserved exactly?
This converter renders your Haddock content into LaTeX with pages, proportions and images kept as close to the original as the target format allows. Use the preview before downloading to confirm it looks the way you expect.
