Frequently Asked Questions
Last updated: September 10, 2026
Is this YouTube to MP3 converter free?
Yes — completely free. There is no registration, no subscription, no hidden limits and no software to install. You can convert YouTube videos to MP3 audio files as many times as you like, right in your browser.
How many YouTube videos can I convert to MP3 at once?
You can batch convert up to 10 YouTube links in one go. Paste one link per line into the box above, click Convert to MP3, and every video is converted to MP3 with its own download button.
What audio quality do the MP3 files have?
Every video is converted to MP3 at up to 320kbps — the highest quality MP3 supports. This keeps your audio virtually indistinguishable from the original YouTube stream.
Is this YouTube MP3 converter safe to use?
Yes. Conversions run over HTTPS, we never ask for your email or password, and we don't inject anything into your browser. Converted files are automatically deleted from our servers within 30 minutes.
Do I need to install an app or create an account?
No. TubeToMP3 works entirely in your web browser — on Windows, macOS, Linux, iPhone, iPad and Android. No app, no extension, no account.
How long do you keep my converted files?
Converted MP3 files are stored only temporarily and are automatically deleted within 30 minutes. We don't keep a copy of your links or files after that.
Does the YouTube to MP3 converter work on mobile?
Yes. The site is fully responsive — paste a link from the YouTube app (Share → Copy link) and convert it to MP3 on any phone or tablet browser.
Is converting YouTube videos to MP3 legal?
Converting content you created, own, or that is in the public domain / openly licensed is generally fine. Downloading copyrighted material without permission may violate copyright law in your country. You are responsible for using this tool only for content you have the right to convert — see our Terms of Use.
Why is my conversion failing?
The most common reasons: the video is private, members-only, age-restricted, or region-blocked; the link is a playlist (paste a single video link instead); or YouTube is temporarily rate-limiting conversions. Wait a moment and try again.
Can I convert long videos or full playlists?
Single videos up to 90 minutes are supported — a progress bar and elapsed time are shown while longer files convert, so you always know where things stand. Playlists are not supported; paste each video link individually (up to 10 at a time).
