Haddock to Reveal.js Converter
Processing entirely on your device — large files may take a moment.
Convert Markdown or Word content into a Reveal.js deck when you need a talk that runs from any browser — no PowerPoint, no install. If your files are still in Haddock format, this page is the shortcut: Haddock is the documentation markup of the Haskell ecosystem: -- comment blocks attached to functions, rendered into the API docs every Hackage package ships.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How Haddock compares to Reveal.js
| Haddock | Reveal.js | |
|---|---|---|
| Structure | Comment markup (--, 'links', @mono@) | Standalone HTML + CDN runtime |
| Best for | Haskell API documentation | Tech talks, courses, demos |

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 Reveal.js format
Reveal.js turns a single HTML file into a full presentation: keyboard-navigable slides, transitions, speaker notes, fragments and even built-in PDF export. The converted file references the Reveal.js runtime from a CDN, so it runs in any browser — nothing to install, nothing to upload.
Headings become slide titles and sections become decks of slides; lists render as fragments you can step through. It is the fastest way from written content to a talk that works on any screen — and the file stays yours, editable in any text editor.
+Strengths
- ✓One file, runs in any browser
- ✓Speaker notes, fragments and PDF export built in
- ✓Editable as plain HTML afterwards
!Limitations
- −Needs internet for the CDN runtime
- −Design is template-driven, less bespoke than PPTX
- −Complex diagrams need hand-written HTML
Why convert Haddock to Reveal.js?
Converting makes sense where the strengths of Reveal.js meet what Haddock cannot give you. One file, runs in any browser 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 Reveal.js 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 Reveal.js?
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.
Can I edit the Reveal.js result afterwards?
That depends on the target: Reveal.js is designed for what it does, and this converter reproduces its content faithfully rather than inventing editable structure. For heavy re-editing, work from a format built for editing and export the final version here.
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.
