Convert HTML to PowerPoint slides

To convert HTML to PPT, drop your .html or .htm file on the tool above, keep PPTX as the PowerPoint version and press Convert to PPTX. You get a deck named after your file, one slide for each page it fills: report.html comes back as report.pptx.

This HTML to PowerPoint converter works in two steps. Your file is first laid out on A4 pages, the way a word processor would print it, and each page is then rebuilt as a slide. A PDF sits in between, which is why the route is graded Very good rather than Exact. From our test report:

• Each line of text became a text box of its own, in its original font, size and colour, with bold and italic intact. A red note set at 20px arrived as 15 pt red Arial.
• Bullets and table cells arrived as editable text as well. The table grid turned into a picture behind them, so it is not a PowerPoint table.
• A chart written into the HTML as a data URI appeared on the slide as a picture. A picture loaded from another web address left an empty gap.
• The slides came out as upright A4 (595 by 842 points), not the wide 16:9 shape decks usually have, and text longer than a page carried on to the next slide.

Many HTML presentations are a single web page in which a script shows one slide at a time. Scripts do not run here, and the CSS that hides the other slides is not applied either, so a deck like that does not come out slide for slide. Our four-slide test deck came back as one A4 slide holding the words of all four, one under the other, and the line its script adds was missing.

There are two ways to keep the slides apart:

1. Save the deck as a PDF first, from its own export or with your browser's Print and Save as PDF. Check that every slide sits on its own page, then convert PDF to PowerPoint: each PDF page becomes a slide.
2. If you can edit the HTML, set the page in its CSS. @page { size: 13.333in 7.5in; } gave wide 16:9 slides of 960 by 540 points, and page-break-before: always on each slide's heading started a new slide. The same break on a section or a div was ignored, so put it on the heading.

Keep PPTX unless the deck has to open in PowerPoint from before 2007, as the help line under PowerPoint version says. Picking PPT (PowerPoint 97) adds a third step: the PPTX is made first and then saved again in the old format. The route then runs HTML, PDF, PPTX, PPT: one more save, in a format that holds less. If you keep the PPTX and need a .ppt later, convert PPTX to PPT does that last step on its own.

The slides themselves matched: turned back into PPTX, the .ppt had the same four slides with the same text boxes and pictures. Our guide to PPT vs PPTX covers which one to send to someone else.

Slides suit a file you want to present. For other jobs, the same .html file converts here too:

• A document to keep editing: convert HTML to Word. Headings become Word heading styles and tables stay real tables, which slides cannot give you.
• A file for a word processor that reads RTF: convert HTML to RTF.
• The words alone, for a form, a search index or a program: convert HTML to text.

Going the other way, convert PowerPoint to HTML turns a deck back into a web page. When the words are in a Word file instead, convert Word to PowerPoint builds slides the same way: one per page, with each line in a text box of its own.
