Free audio tools
Pull the audio out of a video, cut a ringtone from it, squeeze it smaller, or take the vocals out of it — all of it runs in your browser, and the recording never goes anywhere. No sign-up, no watermark.

A recording is every bit as personal as a photo: a voice message, a lecture, an interview, your child's first sentence. Most online MP3 cutters and converters upload it to a server, process it there and hand it back — your recording passes through a stranger's machine, and usually nothing tells you how long it stays. This toolkit does not: both the decoding and the re-encoding happen on your own device, with ffmpeg compiled to WebAssembly.
There is a price, and we are not hiding it: your processor does the work, so a longer recording can take a minute, and the tab has to stay open until it finishes. In exchange there is no daily limit, no queue, and nothing to delete afterwards. There is exactly one exception, and you start it yourself: the "Share with a link" button.
Which one do you need?
If you have a video and only want the sound out of it — a lecture, a concert recording, a voice message that arrived as a video: video to MP3. There you can also ask us not to re-encode anything and simply lift the original track out untouched.
If you need a section of a longer recording — the chorus for a ringtone, the point of an interview: audio trim. It gives you a waveform, so you can see where the part you want begins, and it can produce a ready-made .m4r ringtone for an iPhone. And if the file is simply too big to send: compress audio — where you name an actual number of megabytes rather than a vague "quality".
And if none of them fits: the biggest recording does not need compressing, it needs a link. That is exactly what FileMv is for — the original stays at full quality, and the other person gets a link instead of a 300-megabyte file.
Frequently asked questions
Does my recording get uploaded anywhere?
No. All three tools work inside your browser. Nothing goes up unless you click the "Share with a link" button on the finished file yourself.
How big a file can it handle?
Up to 100 MB of audio, up to 500 MB of video, and up to 10 minutes of either. Not out of caprice: ffmpeg running in a browser works inside a bounded slice of memory, and past that the page does not get slower, it crashes. For anything bigger, upload the original and share it with a link.
Does the sound quality suffer?
If we re-encode, then a little — that is true of every lossy format, and above 192 kbps it is practically inaudible. In two places it does not suffer at all: when we lift the original track out of a video unchanged, and when we cut an MP3 without re-encoding it.
Does it work on a phone?
Yes, and audio is far less work than video — a recording a few minutes long is done in seconds even on a phone. You still have to keep the tab open while it runs.
