Muse to HTM Converter
Processing entirely on your device — large files may take a moment.
Emacs Muse Markup and HTML Document (HTM) exist for different jobs: Muse is the minimal markup of Emacs Muse and Zim wiki — headings with asterisks, emphasis with underscores — designed for note-taking that stays readable for decades. Convert HTM files exactly like HTML: to PDF for printing, to Markdown for editing, or into other documents.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the Muse format
Muse is the quietest markup in this list: an Emacs mode from the early 2000s (later adopted by the Zim desktop wiki) whose headings are leading asterisks, emphasis is underscore-wrapped, and that is most of the grammar. It was designed for personal notebooks that should still open cleanly in fifty years.
Muse files rarely hold anything more exotic than headings, lists and paragraphs, which makes conversion nearly lossless: Pandoc maps the small grammar onto Markdown, HTML or Word one-to-one. The only real work is deciding where the notes go next.
+ Strengths
- ✓Extremely simple grammar — near-lossless conversion
- ✓Future-proof plain text
- ✓Native to Emacs Muse and Zim wiki users
! Limitations
- −Tiny ecosystem outside Emacs
- −No tables or footnotes worth mentioning
- −Effectively unmaintained as a format
About the HTM format
HTML is the markup language of the web itself. A document is plain text decorated with tags that describe structure — headings, paragraphs, lists, links, tables, images — and browsers turn that structure into a rendered, styled page. It is both a format and a program target: CSS styles it and JavaScript makes it interactive.
As a document format, HTML's strength is universality: any device with a browser displays it, text stays selectable and searchable, and links make it navigable. Its weakness is that rendering depends on the surrounding CSS and viewport, so it is a flowing document, not a fixed-layout one — printing or archiving an HTML page is inherently an approximation.
+ Strengths
- ✓Displays on every device with a browser
- ✓Semantic structure: headings, links, tables, media
- ✓Text remains selectable, searchable and accessible
! Limitations
- −Final look depends on CSS and viewport
- −Not a fixed-layout or print format
- −Untrusted HTML must be sanitized before display
Why convert Muse to HTM?
Think of it as moving your file to the container that fits the job. Tiny ecosystem outside Emacs HTM works differently: Displays on every device with a browser If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this Muse to HTM 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 Muse to HTM?
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.
Will the layout of my Muse file be preserved exactly?
This converter renders your Muse content into HTM 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.
Can I edit the HTM result afterwards?
That depends on the target: HTM 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.
