FFmpegRuntime

FFmpegRuntime is an independent, offline front end for FFmpeg on Android. Run real FFmpeg commands on your phone or tablet — no root, no desktop, no cloud. ON-DEVICE FFMPEG • Transcode, trim, extract audio, convert images, remux, generate thumbnails, probe media and more. • A built-in LGPL FFmpeg runtime works out of the box. • Optional dav1d AV1 decoding is included. A REAL TERMINAL • Type commands and tap Run. • Full-colour FFmpeg logs with per-level highlighting. • Tap a finished run to restore its complete output. • Copy output, clear the log, and reuse anything from your command history. SWAPPABLE RUNTIMES • Switch between the built-in runtime and your own custom builds. • Import a runtime as a .zip and activate it in seconds. • Add as many runtimes as you need — each lists its FFmpeg version. YOUR FILES, YOUR DEVICE • Pick photos, videos, audio and documents, or grant access to whole folders. • Browse your workspace, copy paths straight into the terminal, and share results with the Android share sheet. • Everything is processed locally. The app never uploads your files. BUILT FOR THE TERMINAL • Command history keeps your last runs ready to reuse. • Adjust the terminal font size to your liking. • Keep long jobs alive in the background with a progress notification. MADE FOR EVERYONE • Light and dark Material 3 design, adaptive for phones, foldables and tablets. • Available in 15 languages. OFFLINE AND PRIVATE • No account and no sign-in. The app itself needs no internet connection. • Ads and consent-gated analytics keep the app free; they never touch your files or commands. PLEASE NOTE FFmpegRuntime is an independent front end.
