Frequently Asked Questions
Is my audio file uploaded to any server?
No. This tool runs entirely in your browser using **Web Audio API** and **WebAssembly**. Your audio files are processed locally on your device and are **never** uploaded to any server.
What audio formats are supported?
We support exporting to **MP3** (Universal), **WAV** (Lossless), **FLAC** (Compressed Lossless), and **RAW** (PCM). You can import almost any audio file your browser supports (e.g., MP3, AAC, OGG, M4A, WEBM).
Will I lose audio quality?
Converting to **WAV** or **FLAC** is lossless (no quality loss). Converting to **MP3** involves lossy compression, but you can choose up to **320 kbps** bitrate to maintain high fidelity.
Is there a file size limit?
Since processing happens locally in your browser, there is no strict server-side limit. However, extremely large files (e.g., multi-hour recordings) might consume significant system memory depending on your device.
