OTP to MD Converter
Processing entirely on your device — large files may take a moment.
OpenDocument Presentation Template and Markdown Document exist for different jobs: OTP is the OpenDocument presentation template — the same ODF zip as ODP, holding master slides and theme definitions instead of finished slides. Markdown is the fastest way to write formatted text that stays readable as-is and converts cleanly to HTML.
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.

About the OTP format
ODP is the OpenDocument presentation — LibreOffice Impress’s native format, built on the same zip-of-XML idea as PPTX. Files come from public institutions, lecture archives and anyone standardised on open formats.
As with PPTX, text extraction gives you every word in slide order, without the visuals. That is usually exactly what lecture notes and published deck archives are for.
+ Strengths
- ✓Open ISO standard, no vendor lock-in
- ✓Native to LibreOffice Impress
- ✓Same machine-friendly zip+XML
! Limitations
- −Text export drops layout and media
- −Fewer third-party readers than PPTX
About the MD format
Markdown (John Gruber, 2004) is plain text that renders into rich documents: `#` headings, `*` emphasis, lists, links, code fences. You can write it in any editor, read it as-is, diff it in git, and twenty years later it still opens — which is why GitHub, Stack Overflow, Notion, Obsidian and every static-site generator settled on it for prose.
Its one honest weakness is dialect fragmentation: tables, footnotes and task lists all started as extensions (GFM, MultiMarkdown, Pandoc), so a sophisticated document can render differently across tools. Core Markdown — headings, lists, links, code — is bulletproof everywhere.
+ Strengths
- ✓Future-proof plain text, renders anywhere
- ✓Perfect for version control and documentation
- ✓Low-friction: readable even unrendered
! Limitations
- −Extension dialects fragment advanced features
- −Complex layout and precise design are out of scope
Why convert OTP to MD?

Frequently asked questions
Is this OTP to MD 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 OTP to MD?
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 convert a password-protected deck?
No — protected decks are encrypted in the package. Remove the protection in the original application first.
What about speaker notes?
The main extraction covers slide text; notes live in a separate part of the package and are not included in this export.
