Questions people often ask.
Does convert video to audio upload my data?
No. This tool processes your input inside your browser. Your text and files are not sent to an application server. The static host receives page and asset requests; see our privacy explanation.
Is this tool free for work and study?
Yes. No account, paid API, usage subscription or watermark fee is required. You remain responsible for your content rights and checking results. Hosting providers and their free tiers are separate from this open-source software.
What should I check before relying on the result?
Works with MP4, MOV and WebM videos whose sound this browser can play, up to 150 MB and about 5½ minutes of stereo sound. Nothing is uploaded. Needs a browser with built-in audio encoding, such as a current Chrome, Edge or Firefox. Review important outputs against the source, especially financial, legal, identity, medical and research calculations.
Is my video uploaded anywhere?
No. Your browser reads and records the video on your device. Nothing is sent to a server, and the copy disappears from this page when you close it.
Why does it take about as long as the video?
Editing tools play the video once while recording the result, so a one-minute clip takes about a minute. Keep the tab visible until it finishes. Frame, GIF and information tools are much faster.
Will the result be MP4 or WebM?
It depends on your browser. Safari and recent versions of Chrome and Edge record MP4, which plays almost everywhere. Other browsers record WebM, which plays in browsers, VLC and most editors.
