PPT Merger

PPT Merger is a free online tool that combines multiple PowerPoint (.pptx) files into one deck. Each deck keeps its own template, so merging deck B into deck A doesn't break B's layout or fonts. Images, shapes, SmartArt, animations, transitions and embedded video stay intact. Everything runs locally in your browser, so your files are never uploaded to a server, and merges finish in seconds. No sign-up, no watermark, no limit on the number of files.
