PPTX

01 / Fast steps

  1. Drop or select your .pptx files.
  2. Every slide is read in order and shown as text.
  3. Download the HTML outline to keep or share it.

02 / Best for

  • Find out what is in a deck someone sent you before opening Office.
  • Pull the text out of a presentation to reuse it in a document.
  • Read the speaker notes of a talk you were sent.

03 / Why here

  • Slides keep their order and their grouping, so titles stay separate from bullets instead of collapsing into one block.
  • Speaker notes are extracted too, and those are usually the part that explains the slide.
  • Nothing is uploaded: a deck often holds unreleased numbers, and it should not be handed to a converter to be skimmed.

04 / Keep in mind

  • This reads the text, not the design: layout, theme colours, charts and images are not reproduced.
  • A slide whose content is a picture of text has no text to read, and is reported as empty.
  • The older binary .ppt format is not supported, only .pptx.

faq

Questions, answered.

01What is inside a .pptx file?

A ZIP archive with one XML part per slide, ppt/slides/slide1.xml and onwards, plus the images in ppt/media and the theme and layouts in their own parts. Each slide lists its shapes, and each shape holds paragraphs of text. This is the same Office Open XML family as .docx, standardised in 2006, which is why a presentation can be read without any Microsoft software.

02Why can the slides not be shown as images?

Because the appearance is not stored in the file. A slide references a layout, which references a master, which references a theme, and PowerPoint resolves that chain at display time together with font metrics and its own rendering of charts and effects. Producing a faithful picture means reimplementing PowerPoint, and any shortcut yields slides that look almost right, which is worse than an honest text outline.

03Are speaker notes included?

Yes, when the deck has them. They live in separate parts, ppt/notesSlides, one per slide, and are shown under the slide they belong to. It is worth knowing that they travel inside the file: notes you wrote for yourself are visible to anyone you send the .pptx to, whether or not they open the notes pane.

04Is my presentation uploaded anywhere?

No. The ZIP is opened and the slide XML parsed by JavaScript in your browser tab. Decks are one of the most sensitive things people exchange, since they routinely carry unreleased figures and internal plans, so a viewer that receives a copy of the file solves one problem by creating a larger one.
