Voice note, not a file
An MP3 arrives as a regular file — you have to open it separately. The bot turns it into a voice message: it plays in the chat, and you can speed it up to 1.5× or 2×.
AudioConvert Bot
Convert audio in Telegram — voice, OPUS, MP3.
Turn a file into a voice message, make it smaller, or change the format — MP3, M4A, OGG, WAV, OPUS. All in Telegram, no apps to install.
For everyday jobs: voice messages, quick compress, and repeat last conversion.
Why people open the bot
Shrink so it fits
An hour of recording can weigh about 58 MB, and the Free limit is 50 MB. The bot reduces the file size and keeps the full duration.
So it opens everywhere
M4A, OGG or WAV will not open on every device. Convert them to MP3 — for Windows, a car stereo, a USB stick, or upload to other services.
Same as last time
You don’t need to pick format and settings every time. Repeat the last conversion in one tap.
Text from a voice note
Need to save or find something from a voice message? The bot transcribes up to 10 minutes into text in the original language.
