Question 1

What video formats are supported?

Accepted Answer

The tool supports the most common video formats including MP4, WebM, MOV, AVI, MKV, and FLV. The output audio can be downloaded as MP3 or WAV.

Question 2

Is my video uploaded to a server?

Accepted Answer

No. All processing uses FFmpeg compiled to WebAssembly, which runs entirely in your browser. Your video file never leaves your device.

Question 3

Why does it take time to start the first conversion?

Accepted Answer

The first time you use the tool, it needs to download the FFmpeg WebAssembly engine (~31MB). This is cached in your browser so subsequent uses start instantly.

Question 4

What is the difference between MP3 and WAV output?

Accepted Answer

MP3 is a compressed format with smaller file size, ideal for music and speech. WAV is uncompressed with higher quality and larger file size, ideal for audio editing workflows.

Question 5

Is there a file size limit?

Accepted Answer

There is no enforced limit, but very large files (over 500MB) may be slow to process depending on your device's memory and CPU. For best results, use files under 200MB.
