PPTX to Markdown, HTML or Plain Text: Get Every Word Out of a PowerPoint Deck
A slide deck is a terrible place to keep words. They are locked one screen at a time behind a layout, and the moment you want them somewhere else — a study document, a wiki page, a prompt for an AI assistant — you are clicking through slides copying boxes one by one. This tool turns a PPTX to Markdown, a structured HTML page or a plain text outline in one pass, keeping slide titles, the bullet hierarchy and the speaker notes together. It is the quickest way to extract text from PowerPoint without opening PowerPoint. This guide covers what comes out, what PowerPoint’s own export silently leaves behind, and what this tool deliberately does not do.
1. What This Tool Actually Does With a Deck
A .pptx file is not one opaque blob. It is a package of parts described by the ECMA-376 Office Open XML standard, with a separate part for each slide, another for each slide’s notes page, and a list at the front giving the slide order. Every piece of text you typed onto a slide lives in one of those parts as a shape with paragraphs inside it, each carrying its own indent level.
This tool reads those parts in the deck’s own slide order and builds a text outline: for each slide, the title, then every non-empty paragraph from every text shape with its indent level, then the speaker notes. It writes the result as one of three files: a Markdown outline, a structured HTML page, or a plain text outline.
That is the whole job. It does not draw the slides, does not carry images or charts across, and is not a presentation format converter — it will not turn a PPTX into PPT, ODP or Keynote. If the goal is the words, this is the right page; if the goal is a different presentation file, section 6 explains why we do not pretend otherwise.
2. How to Convert PPTX to Markdown Online Free (Step-by-Step)
No account, no email, no watermark and no slide cap. To use the PPTX to Markdown converter online free at the top of this page:
Choose your .pptx
Click the panel above and pick one PowerPoint file. It has to be a .pptx rather than a legacy .ppt; section 6 covers older files.
Check the preview
The tool reports how many slides it found and shows a live preview of the outline, so you can confirm it read the deck you expected.
Pick a format and download
Choose Markdown (.md), Structured Web HTML (.html) or Plain Text (.txt) and press download. The file is named after your deck.
Once the deck is loaded you can switch format and download again as often as you like. Markdown opens in any text editor and pastes cleanly into a notes app, a wiki or a chat window, which is why PowerPoint to Markdown is the export most people come here for; PPTX to TXT is the one to pick when you want the flattest possible dump. Nothing you convert is stored on our servers or kept after your session ends.
3. The Text PowerPoint’s Own Outline Export Leaves Out
If you have already tried to copy all text from PowerPoint at once, you have probably met Outline View, File > Export > Create Handouts > Outline Only, or saving the deck as RTF. They share one limitation: they only see text inside placeholders — the title and body boxes that come with a slide layout. Anything typed into a text box or shape you inserted yourself is not outline text as PowerPoint understands it, so it vanishes from the export.
That is why searches like PowerPoint outline view missing text boxes and PowerPoint export outline only text boxes not included are so common. The deck looks complete on screen; the outline is missing the callout beside the chart, the caption under the photo and the three-column comparison built from separate boxes.
This tool does not use the placeholder distinction to decide what to keep. It scans every text shape on every slide — layout placeholders and manually inserted boxes alike, including boxes inside a group — and takes every non-empty paragraph. The title becomes the heading and everything else becomes a bullet beneath it, in the order the shapes appear. The outline you download carries every text box’s words, not just the subset PowerPoint considers real outline text.
One honest side effect of reading everything: subtitles, footers and date fields are ordinary text shapes too, so a visible footer appears as a bullet, and hidden slides are included because a hidden slide is still a slide in the file. Both are seconds of tidying, which is a better problem than text that never arrived.
4. How to Get Speaker Notes Out of PowerPoint Without Slide Images
The other thing people want from a deck is the notes pane: a lecturer’s script, a colleague’s talking points, the sources tucked below a chart. PowerPoint’s answer is Export to Word, which produces a table with a thumbnail of each slide, its number and the notes beside it. If what you wanted was PowerPoint notes to Word without slide images — just the words, in order — that leaves you deleting a column of pictures by hand.
Here, the notes are attached to their slide in the output. In the Markdown outline they arrive as a quoted “Notes:” line beneath the bullets; in the HTML page they sit in a highlighted block at the bottom of each slide card. Either way you get speaker notes out of PowerPoint already paired with the slide they belong to, with no thumbnails and no table to dismantle. The slide-number field PowerPoint stores on every notes page is dropped, so there is no stray “7” at the end of each note. It is PPTX to Markdown with speaker notes, not notes as a separate document.
One thing to know first: the plain text export does not include notes. To export PowerPoint speaker notes to a text file, pick Markdown. A .md file is a plain text file — the text/markdown media type is defined in IETF RFC 7763 — and it opens in exactly the same editors, with the notes kept.
5. Markdown, HTML or Plain Text: Which Output to Pick
The three formats share the same source outline but differ in what they keep, so the choice depends on where the text is going next.
Markdown Outline (.md)
The deck name as a top-level heading, then a second-level heading per slide (“Slide 4: Title”), bullets indented two spaces per level, and a “Notes:” blockquote where notes exist. Best for Obsidian, Notion, wikis, READMEs and AI prompts.
Structured Web HTML (.html)
A single self-contained, dark-themed page with one card per slide, real nested lists for the bullet levels, line breaks kept inside paragraphs, and a highlighted speaker notes block. Best for reading a deck as a web page or sharing one scrollable page.
Plain Text Outline (.txt)
“SLIDE 4: Title” followed by one bulleted line per paragraph. No indentation and no speaker notes. Best when you want to convert PPTX to a plain text bullet outline — titles and bullets in order and nothing else.
Two long-tail questions answer themselves here. Yes, PPTX to Markdown preserves bullet indentation: every paragraph’s indent level is read from the slide and written as two spaces per level, so a sub-bullet stays a sub-bullet. And yes, PPTX to HTML here means an outline on one page — every slide’s text in one scrollable document — not a slide-by-slide replica. Because that HTML is complete in one file, you can turn it into a printable document with save web page as PDF if a PDF of the outline is what someone asked for.
The Markdown export is also the answer to paste PowerPoint into ChatGPT or any other AI assistant: a heading per slide, bullets under it and the notes quoted beneath gives the model the structure of the talk in one prompt instead of twelve copy-pastes. Students turning lecture slides to Markdown notes for Obsidian or Notion get a file that drops straight into a knowledge base with the slide numbers intact.
6. What Is Skipped, and Where to Go Instead
The promise is “every word in every text shape”, and its edges are worth stating plainly.
- Tables, charts and SmartArt are not read. Their text is stored differently from an ordinary text shape, so a slide that is one big table comes out with its title and nothing else. The same goes for embedded spreadsheets and other objects.
- Images are not extracted. Text that only exists inside a picture — a screenshot, a photographed whiteboard — is invisible here. If the deck is really a set of scanned pages, save it as a PDF from your presentation app and run it through PDF OCR instead.
- Formatting is not carried across. Bold, italic, colour, font size and hyperlinks are dropped, and so are layouts, themes, backgrounds, animations and transitions. The output is plain text with structure.
- Only .pptx is accepted. A legacy binary .ppt, an OpenDocument .odp or a Keynote .key is refused with a “Could not read PPTX” message. Save it as .pptx from your presentation app first and it will read normally.
- One deck at a time. There is no batch mode; loading a second file replaces the first.
And the big one: this is not a PowerPoint format converter. It will not produce a PPT, ODP, Keynote or Google Slides file, and it will not build slides from a Markdown outline in reverse. We do not currently offer format-to-format presentation conversion, and we would rather say so than route you to a page that cannot do it. If you have a PDF and want an editable deck, PDF to PowerPoint is the tool for it. The broader file converter hub lists everything else we convert.
7. Why Cortexis Is the Best Free PPTX to Markdown Converter
Free, with no sign-up
A PowerPoint to text converter online free, no sign up, no email and no trial that expires. Every deck, every time.
Unlimited, with no watermark
Extract supported PPTX text locally within the displayed limits. Original slide designs, media and animations are not preserved.
Reads the text boxes PowerPoint skips
Manually inserted text boxes, grouped shapes and layout placeholders are all read, so the outline matches what the slide shows.
Speaker notes stay with their slide
Notes are attached beneath the slide they belong to in Markdown and HTML — no thumbnails, no Word table, no stray slide numbers.
Bullet hierarchy survives
Indent levels become nested lists in HTML and two-space indentation in Markdown, so sub-points do not collapse into one flat list.
Your deck stays private
Nothing you convert is stored on our servers, retained after your session, or used for training or analytics.
It sits alongside a wider set of free document tools on the same terms; the spreadsheet converter and ebook converter do the equivalent job for spreadsheets and ebooks.
8. Frequently Asked Questions (FAQ)
How do I convert PPTX to Markdown for free?
Choose your .pptx in the panel at the top of this page, wait for the slide count and preview, select Markdown Outline (.md) from the dropdown and press download. No account, no email, no watermark, and it works the same on the hundredth deck as the first.
Can I read a PPTX without PowerPoint?
Yes. This page lets you read PPTX without PowerPoint or any Office licence. Load the .pptx and the preview shows every slide’s title, bullets and notes as a scrollable outline. Download the HTML version to keep a readable copy, or Markdown if you want to edit it.
Does PPTX to Markdown keep speaker notes?
Yes, in Markdown and HTML. Each slide’s notes are placed directly under that slide as a quoted “Notes:” line in Markdown or a highlighted block in HTML. The plain text (.txt) export does not include notes, so choose Markdown if you specifically need notes in a text file.
Why does PowerPoint’s outline export miss some of my text?
Outline View, RTF export and Create Handouts > Outline Only read only placeholder text — the title and body boxes that come with a layout. Text boxes you inserted yourself are not outline content to PowerPoint, so they are dropped. This tool reads every text shape on the slide, placeholder or not.
Can I convert PowerPoint to HTML without PowerPoint?
Yes. Choose Structured Web HTML and you get a single self-contained page with one card per slide, nested lists for the bullets and a speaker notes block. It is a text outline on one page, not a visual copy of the slides, so design and images are not included.
Does it convert PPTX to PPT, ODP or Keynote?
No. This tool extracts text; it does not convert between presentation formats or produce PDF, images or a new slideshow. For a different presentation file, use Save As in your presentation app. If you have a PDF and want an editable deck, use our PDF to PowerPoint tool.
Will tables and charts on my slides be included?
No. Only text inside ordinary text shapes and placeholders is read. Text in tables, charts, SmartArt and embedded objects is skipped, as is text that only exists inside an image. A slide that is entirely a table comes out as just its title.
Got the outline and need to go further? The JSON formatter tidies structured data you are pasting alongside it, PDF to Word handles the deck someone sent you as a PDF instead, and PDF to HTML does for documents what this page does for slides. If you would rather understand how HTML and Markdown are built than simply generate them, our free full-stack web development course starts with the structure of a web page and goes on from there.
