PPT Merger is a free, browser-based tool that combines multiple PowerPoint files into a single presentation without uploading anything.

Pick the exact slides you need: visual thumbnails let you select individual pages, apply ranges and reorder source decks before merging, so unwanted title pages, appendices and duplicate sections never make it into the final file.

Formatting survives the merge. Fonts, colours, layouts, slide masters and transitions come through intact, which means no manual clean-up after combining decks from different authors or template versions.

Nothing is uploaded. All processing happens locally in your browser using a Web Worker, so confidential board decks, client pitches and proprietary research never leave your device. There is no account to create, no watermark on the output and no file size limit.

It is built for consultants, sales teams, students, educators and anyone who regularly stitches together slides from several team members.
