What are the limits of Video to Audio?
Files stay on your device. A pinned FFmpeg WebAssembly engine (about 31 MB) downloads from jsDelivr on first use; an internet connection and a modern WebAssembly browser are required. Processing uses one worker thread and can be slow or memory-intensive on phones. Cancel stops the worker. Export re-encodes media, strips metadata and cannot recover missing quality. Encrypted or DRM-protected media is unsupported. Up to 250 MB combined, 10 minutes per input and 10 minutes of output. A video must contain an audio track. MP3 is lossy; WAV is 16-bit PCM. Unsupported native previews can still be processed by the engine.
