Extract text from PowerPoint presentations (PPTHTML)
To convert PPTHTML presentations to another format, you need Microsoft PowerPoint or other Web software.
To convert other file formats to the "Legacy Web Presentation File" file type, you need software like Microsoft PowerPoint or a similar tool.
The .PPTHtml format is an outdated Microsoft PowerPoint HTML Presentation file. It was created when users saved legacy slide decks as web pages using the "Save as Web Page" feature in older versions of Microsoft PowerPoint.
This format is notoriously fragmented and problematic. A .PPTHtml file is rarely standalone; it acts as an index document that relies entirely on a companion folder full of XML, image, and CSS assets. If you separate the file from its asset folder, it becomes useless. Furthermore, the HTML code generated by older PowerPoint versions relies heavily on proprietary tags, VML (Vector Markup Language), and ActiveX controls. This causes severe rendering errors and broken layouts in modern web browsers like Chrome or Firefox.
To restore usability, you need to convert this file into a self-contained, modern format like PDF for reliable sharing, or back to PPTX for editing.
Because it relies on outdated Microsoft-specific web standards and external asset folders, standard online converters often fail to process it correctly.
Convert.Guru analyzes your PPTHTML file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PPTHTML converter.
