Frequently Asked Questions
Is it safe to extract FLAC from MKV offline?
100% safe. instaBatch processing keeps your MKV recording in local browser memory — no remote transfers, no third-party storage.
Will extracting FLAC from my MKV video reduce the sound quality?
Quality is protected because the instaBatch engine isolates the embedded audio from MKV before encoding to FLAC — no redundant re-compression steps.
