- Add the modified PPTX file to the right panel.

Tip: FileDiffs compares the available text in your slides. It works in modern browsers including Chrome, Edge, Firefox and Safari. You can review differences using Side-by-Side and Original/Modified views and export a comparison report when needed.
Compare Different Versions of a Presentation
PowerPoint presentations often pass through several revisions before they are ready to present. Slide titles may be rewritten, bullet points shortened, figures updated, or entire sections revised between versions.
FileDiffs compares the original and modified PPTX files directly so you can identify text changes without opening both presentations and checking every slide manually.
This is especially useful when two finished presentation files are available but there is no reliable revision history showing what changed.
Review Slide Deck Revisions Before Presenting
PowerPoint comparison is useful across presentation workflows such as:
- Sales decks — Check changes to pricing, product claims, benefits or customer messaging.
- Investor presentations — Review updated figures, financial metrics, forecasts or slide wording.
- Project presentations — Compare revised milestones, timelines, responsibilities or status updates.
- Training decks — Find updated instructions, policies or learning material between versions.
- Marketing presentations — Review changes to campaign messaging, statistics or recommendations.
- Academic presentations — Compare revised research findings, conclusions or presentation text.
Comparing PowerPoint presentation versions helps you focus on changed slides instead of reviewing the entire deck again.
What Changes Can PowerPoint Compare Detect?
FileDiffs compares the available text from both PPTX files and identifies changes such as:
- Slide titles — headings that were added, deleted or rewritten
- Bullet points — changes to list items and presentation summaries
- Body text — edited sentences, paragraphs or explanations
- Numbers and dates — revised figures, percentages, deadlines or other values
- Table text — changes to selectable text inside presentation tables
The differences are displayed side by side so you can quickly review changed presentation content.
Examples of PowerPoint Differences

- Revenue forecast — $2.5M changes to $3.1M on a financial slide.
- Project deadline — September 15 changes to October 1.
- Sales message — Reduce costs by 20% changes to Reduce costs by up to 30%.
- Bullet point update — a new product benefit is added to a feature slide.
- Deleted wording — an outdated statement is removed from a presentation.
FileDiffs highlights these text differences so you can quickly review important slide changes without checking the entire presentation manually.
