Convert PPT or PPTX to HTML

To convert PPTX to HTML, press Select PowerPoint file or drop a .pptx or .ppt anywhere on this page, then press Convert to HTML. There is nothing to set. You get one .html file named after your presentation, so pitch.pptx comes back as pitch.html, and that name doubles as the title on the browser tab. Expect a web document rather than a slideshow: everything visible runs down a single long page, with nothing to click through.

Our server has no direct way from a presentation to a web page, so this PPT to HTML converter takes three steps, shown as PPTX to PDF to DOCX to HTML. First comes a PDF, then that PDF is rebuilt as a Word document, and finally the Word document is saved as HTML. Every rebuild shifts something, which is why the PowerPoint to HTML route is graded Good enough. Our seven-slide test file came back like this:

• Titles, text boxes and table cells arrive as words you can select and edit. A title is large bold lettering, not a real web heading, and bullets are a typed • rather than a web list.
• Two boxes placed side by side end up in a borderless table, one per column. A picture with a caption next to it is held the same way.
• A real table stays a table, every cell in place.
• Words on the slide master, such as a school name in a corner, repeat once for each visible slide.
• Speaker notes and the hidden slide were missing, just as they are from a PDF.

Every picture travels inside the .html file, so there is no folder of images to keep with it. Each keeps all its pixels and is shown at the size it was placed. They are stored as PNG, though, photos included: a 460 KB JPEG photo became a 3.6 MB PNG, and the HTML weighed 4.8 MB against 470 KB for the .pptx. If the pictures add up to more than 50 MB, you get a ZIP holding the HTML and its pictures instead.

A presentation with no typed text at all, such as scanned handouts or exported images, has nothing to rebuild. Its English words are read from the slides instead, and the result holds the words but none of the pictures. In our two-page test every line was found, though one capital S became an o.

The markup asks for the fonts our server used, Carlito in place of Calibri for example, and falls back to a serif font, so on a computer without Carlito the words show in a serif type. Blank areas become margins, which leaves wide gaps between blocks of text, and two bullets from one box can run together on a line. Anything laid out side by side sits in a table 1280 pixels wide for a 16:9 original, wider than a phone screen.

To show a presentation on a website the way you designed it, another conversion usually serves your visitors better:

• Convert PowerPoint to PDF to keep the design exactly as it is, one page each. That takes one step and is graded Exact; then link to the PDF from your site.
• Convert PowerPoint to GIF for a show that runs by itself: one looping GIF with a frame for each slide, held for the time you choose, which plays on any web page.
• PowerPoint to PNG or PowerPoint to JPG gives one picture per slide, together in a ZIP, to place on a page like any other image.
• PowerPoint to Word suits reworking the wording: an editable page for each slide, with size and bold kept.

Need only the words? Convert PowerPoint to text for a plain .txt file, or convert PowerPoint to RTF for a document almost any word processor opens. The RTF takes the same PDF and Word steps as this page. Going the other way, convert HTML to PowerPoint to turn a saved web page into a presentation.

You can convert PPT to HTML as well: a file from PowerPoint 97 to 2003 goes in as it is. To keep editing it in PowerPoint rather than publish it, convert PowerPoint to PPTX first.
