Frequently Asked Questions
Which video formats can I convert to MP3?
MP4, MOV, WEBM, MKV, M4V and AVI all work — anything with a standard audio track. The tool extracts the audio stream and re-encodes it to the format you pick (MP3 by default, or WAV / M4A).
Is my video uploaded to a server?
No. The extraction runs entirely inside your browser using WebAssembly. Your video never leaves your device — nothing is uploaded, stored, or seen by anyone.
What is the maximum file size?
Up to 200 MB. Because processing happens in your browser's memory, very large videos can be slow on phones — for long recordings, a laptop will be faster.
Does it work on a phone?
Yes, on modern Android and iPhone browsers. The first use downloads the conversion engine (about 30 MB, one time, then cached). Very large videos are best done on a computer.
Which bitrate should I choose?
192 kbps is a good default for speech and general use. Choose 320 kbps for music where quality matters, or 128 kbps for the smallest file (voice notes, WhatsApp).
Key Terms
Bitrate (kbps)
How much data per second the audio uses. Higher bitrate = better quality and larger file. 128 kbps is compact, 192 kbps balanced, 320 kbps near-CD quality.
MP3 vs WAV vs M4A
MP3 is the universal compressed format. WAV is uncompressed (large, lossless). M4A (AAC) is Apple's compressed format, slightly better than MP3 at the same bitrate.
WebAssembly (WASM)
Technology that lets near-native programs like FFmpeg run inside your browser — which is how this tool converts locally without uploading your file.
