MarginDiff Presentations
Compare PowerPoint presentations and review changes to slide content, formatting, and appearance.
See the story change.
Review two versions of a PowerPoint presentation with matched slides, source slide numbers, and image and text panels. Follow revisions to the message as well as the layout.
The comparison features described here are in testing and are not in the latest installers. A public installer is not currently listed. Contact us to confirm availability and supported features before ordering.
Look beyond the slide image
- Text and formatting. Review text edits and supported formatting changes, including formatting inherited from slide layouts and themes.
- Shapes and layout. Detect added or removed objects, changes in position and size, and changes to stacking order.
- Tables, images, notes, and links. Compare table content, saved image data, speaker notes, and explicit hyperlink destinations or actions.
- Slide order. Keep matched slides aligned. Inserting a slide does not automatically mark every later slide as moved.
Review content and appearance together
Choose File > New Diff, select the Original and Modified presentations, choose a saved style, and select Start. Use Override for options that apply only to this comparison.
Content comparison checks supported saved properties; visual comparison checks rendered slide images. A changed link can matter even when a slide looks the same. Equally, rendering differences can make slides look different when their supported content matches. Review both results.
Follow revisions and speaker notes
The Revision List brings changes together across slide pairs. Select an entry to open its slide and highlight the object when available. Use Find to search redline text and Goto to jump to a compared slide.
Select and copy supported comparison text. The Speaker Notes pane offers Original, Modified, and Redline tabs; selecting a speaker-note revision opens its redline. Notes are read-only and do not reproduce notes-page artwork.
Share a review copy
Save Diff can create a PPTX redline with editable comparison text where supported. Graphics and complex grouped text use rendered comparison images. Animations, embedded objects, and the notes shown in the review pane are not retained in this review copy.
Export an HTML or PDF comparison report, preview it for printing, or prepare attachments in desktop Outlook for review before sending. Redline Save requires a new filename and cannot overwrite either source presentation.
Prepare your PowerPoint files
PPTX files open directly. Older PPT files require PowerPoint for conversion. Install the fonts used by the presentation and check complex artwork in PowerPoint when exact appearance matters.
Charts and SmartArt are compared as whole objects, without a complete breakdown of their editable properties. Duplicate slides or recreated shapes can make matching less certain. Table alignment, inherited styles, and links across reordered slides have limits. Very large decks or slide images can exceed preview limits.
MarginDiff’s preview does not guarantee exact PowerPoint rendering or coverage of every PowerPoint feature.
