About the ODP 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 MHT 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

Frequently asked questions
Is this ODP to MHT 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 ODP to MHT?
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 ODP to MHT keep the slide order?
Yes — slides are read from the file in their real order and numbered, so the output follows the deck exactly.
Does the conversion include images and backgrounds?
No. This is a text extraction: words on slides survive, layouts, backgrounds, animations and pictures do not. Keep the original deck for the visuals.
