mp3 tools bot: audio to mp3

Someone sent a voice message with a lecture and you need a file that opens in any player. Or your phone holds a concert video and you only want the sound. mp3 tools bot turns such files into a regular mp3 right in a Telegram chat 🎧

What the bot accepts

The description names three kinds of material, which covers most everyday tasks:

• A music file. Any audio file, including one that is already mp3.
• An mp4 video. The bot takes the sound track out of the clip.
• A voice message. A recording from a chat becomes a file you can keep.

The result comes back to the chat as an mp3. From there you can download it, forward it or add it to a player.

What it looks like in practice

1. Open the bot and press /start.
2. Send a file: audio, an mp4 video or a voice message.
3. Wait for the reply with the finished mp3.
4. Save the file to your device.

If the bot hangs, /start restarts it. The /legal command shows legal information about the service.

Why mp3 at all

Mp3 is the most widespread audio format: phones, car stereos, speakers and old players all understand it. The file is compressed, so it takes little space.

Compression loses some quality, but for speech, lectures, podcasts and everyday music the difference is usually inaudible. For studio recordings, keep the original in a lossless format 🎼

What to pull out of a video and what to leave

Sound from a video is useful in a few situations:

• a lecture or webinar you want to hear on the road;
• a family celebration recording that keeps the voices;
• your own performance or rehearsal;
• an interview where you only need the conversation.

If the original recording sounds poor, mp3 will not improve it: it repeats what is in the clip.

Copyright and privacy

Convert your own recordings and material you have the right to use. Uploading other people's music and films to share them is not allowed, and in some countries even keeping such copies is risky.

The file passes through the service's server, so do not send recordings with private conversations, work secrets or documents. For those, software on your own computer is a better choice 🔒

If the result disappoints

• Quiet sound. Check the volume of the source and send it again.
• No reply. Restart the bot with /start and resend the file.
• A file that is too large. Telegram limits attachment size, so trim a long video first.
• An odd format. Save the video as mp4 and try again.
