Offline, zero-permission Android viewer for PDF, Word, Excel, PowerPoint, photos, video, audio, Markdown and code. **[Matthew Laird](https://daily.dev/sources/u-uk0giik)** · [@hvk500](https://daily.dev/hvk500) · 21 upvotes · 3 comments ## Summary Gander is a tiny open-source Android file viewer (about 15 MB APK) that renders PDF, Word, Excel, PowerPoint, photos, video, audio, Markdown, and code entirely on-device with zero permissions, no internet access, no ads, and no tracking. It uses the Storage Access Framework and sandboxed WebViews with bundled JS libraries to handle Office formats offline. Features include pinch zoom, recent files with thumbnails, folder browsing via one-time system grants, in-document search, and full Material 3 support on Android 8.0+. Built 100% in Kotlin, it can be installed via sideloaded APK or tracked through Obtainium for automatic updates. ## Full article daily.dev links to this article rather than hosting it.
