Copy-pasting slides between decks in PowerPoint asks whether to keep the source formatting, and the answer is often wrong: fonts change, backgrounds disappear and charts lose their data. This merger copies each slide together with everything it depends on — its slide layout, slide master and theme, pictures, audio and video, charts with their embedded data, SmartArt and speaker notes — so the merged deck looks exactly like the originals, slide for slide.
Pitch decks, board papers and client presentations should not be uploaded to a stranger’s server just to join them. Here the files are read and combined by your browser on your own device — nothing is sent anywhere, and it keeps working if you go offline after the page loads.
Need a PDF instead? Export each deck to PDF and use the PDF Merger. Combining Word files? Use the Word Merger.
