Free PPTX Compare Tool
Compare PowerPoint presentations in your browser by extracting slide text and speaker notes.
Browser-side PPTX comparison
PPTX files are parsed locally in this browser. The tool extracts slide text and notes without uploading your presentations.
Original presentation
Modified presentation
Compare slide text
The tool extracts text runs from each slide and shows wording changes in a side-by-side diff viewer.
Include speaker notes
Speaker notes are extracted when present, so presenter notes can be reviewed alongside visible slide text.
Text-focused comparison
This first version compares textual content, not slide layout, animations, images, charts, or visual formatting.
