What is a .PRS file?
Everything worth knowing about Harvard Graphics Presentation File files.
A PRS file is a presentation created with Harvard Graphics for Windows versions 1 through 3 (1991 to the mid-1990s). The software is discontinued. Opening PRS files today is difficult; you need a legacy copy of Harvard Graphics or an older version of Corel Presentations.

Is my .PRS file uploaded anywhere?
No. Your .PRS file is unpacked and drawn for you.
Will it look exactly like in PowerPoint?
Close, but not pixel-perfect. Text, shapes, pictures, tables, colours and the theme are redrawn from the file. Animations, transitions, charts, SmartArt and some special effects are simplified or skipped.
Can I see the speaker notes?
Yes. Notes appear under the current slide whenever the author added them, and they're counted in the info panel.
What about old .PPT files?
For PowerPoint 97-2003 files the viewer extracts the text of every slide, titles and bullets included, but doesn't draw the layout yet. Save the file as PPTX for a full preview.
And Apple Keynote?
Keynote files keep their slides in a proprietary format. If the file contains its built-in preview image we show it; otherwise export the deck from Keynote as PPTX or PDF.
