PPT Compactor

Clean oversized .pptx files

Only for Mac

Free

Mac

Shrink bulky .pptx files on your Mac by compacting large slide images, removing unused media, and freezing videos or GIFs. PPT Compactor helps shrink oversized .pptx files before you send, upload, or archive them. Open a .pptx file, review every embedded media item, compact large used slide images, and save a cleaned copy. The app highlights unused media, shows file sizes, and identifies where media is used in the deck, including whether an item is inside or outside the visible slide boundary. What it can do: - compact large used slide images - remove unused embedded media - convert embedded videos to still frames - convert animated GIFs to still PNG images - keep used media safe by default - export or copy selected media files - preserve your original file by writing a cleaned copy PPT Compactor runs locally on your Mac. It does not upload your presentations, does not require an account, and does not use analytics.

Media now stays media. Videos, animated GIFs and audio can be compressed instead of flattened to a still image, at High quality, Balanced or Smallest. GIF compression removes duplicate frames without changing the animation, so a screen recording shrinks a long way while playing exactly as before. Videos and animated GIFs now play inside the app, and any item can be opened full screen with zoom and pan. A new slide view sits beside the preview and shows where the selected media actually sits on its slide, so you can see what you are about to change. Cropped pictures can have the hidden cropped-away area trimmed with no recompression and no quality loss, or compressed and trimmed together for the smallest file. The media list has been rebuilt around per-item action checkboxes, with Auto-select, Select all and Deselect all presets. Nothing is applied unless you check it. Media parked entirely outside the slide, and media referenced only by unreachable parts of the file, are now flagged for removal by default.
