PPTX Viewer: Read Slide Text, Notes and Images

Drop a .pptx file and the viewer lists every slide in order. Each slide shows its title, its body text, any tables, the speaker notes and embedded pictures as thumbnails, with the slide count at the top. It is built for reading and reusing the content of a deck: finding what a slide says, pulling the notes out, or checking an inherited presentation without installing PowerPoint.

Copy all text to the clipboard, or download it as plain text or Markdown. The Markdown export puts each slide under its own heading, with lists and tables in Markdown form, so you can paste a talk outline into documentation or a README and edit it with the Markdown viewer.

A .pptx file is a zip archive of XML files, one per slide plus parts for notes, relationships and media. The viewer unpacks the archive in your browser with the fflate library, reads the slide order from the presentation part, and walks each slide's XML for text and tables. Nothing is sent over the network.

Pictures are shown only when they are PNG, JPEG, GIF, WebP or BMP, because those are the formats a browser can draw. Other image types are not shown. Slides appear in the order the deck defines, not in the order of file names inside the archive, which differ in decks where slides were reordered or deleted.

This shows content and structure, not pixel-perfect slides. Themes, layouts, animations, transitions, shapes, fonts, charts and SmartArt are not rendered. Text that lives inside a chart, SmartArt or a grouped image may be missing from the output, so a slide that looks full in PowerPoint can look sparse here. If you need the exact look of a slide, export the deck to PDF from PowerPoint and open it in the PDF viewer.

The old .ppt format and password-protected files are not supported, and a plain message tells you so. Files up to about 50 MB are accepted. A common pitfall is a deck made mostly of screenshots: the text is in the pictures, so the extracted text will be short. In that case the thumbnails are the only record of what is on the slide, and there is no OCR to read them.
