.pptx · PowerPoint (PPTX)
Open .PPTX files in your browser
Open PPTX decks in your browser with a canvas slide viewer — shapes, images, and charts render locally.
How it works
- Open Filelathe and drop your file (avoid macOS Finder Recents — use the real folder).
- A dedicated tool window opens for this format.
- Use the on-page controls to view or edit.
Filelathe opens .pptx with pptx-wasm in your tab: navigate slides, see charts and images, and keep the file on-device. No Office install and no upload.
Privacy
File bytes are read in your browser for viewing and playback. Unlike upload-to-convert sites, Filelathe is built around in-tab tools. API calls may use filename, type, and small samples to choose or invent a UI.
