FAQ

A .mp3 file is a lossy audio format — the web's default for music. It encodes sound data for playback and streaming.

MP3 is universally supported — use it for anything that needs to "just play".

Yes — conversion runs entirely inside your browser using WebAssembly. Your files never leave your device, never touch our servers, and we have no way to see or store them. Open DevTools → Network tab while converting; you'll see zero upload traffic.

Video and audio conversion works on iOS 16.4 and later (requires SharedArrayBuffer support). Older iPhones can still convert images without issues.

There's no hard limit we enforce, but the converter is bounded by your device's RAM. Phones typically handle files up to ~500MB comfortably; laptops can push into multi-GB territory. If your file is very large, try splitting it first.

Most online converters upload your file to their servers, process it there, and let you download the result. That means trusting them with potentially sensitive media. This tool skips the server entirely — the same FFmpeg code runs in your browser via WebAssembly, so nothing is uploaded, nothing is stored, and it's free forever.
