Example: a short OGG transcript
Speaker 1Hey, it's me. I'm stuck in traffic, so just listen to this when you can.
Speaker 1The landlord called back, he's fine with us moving in on the first, but he wants the deposit by Friday.
Speaker 1Can you send me your half tonight? I'll do the transfer tomorrow morning.
Voice messages are usually OGG Opus
If someone sent you a voice message and you saved it, there's a good chance it's Opus audio in an OGG container. Opus was designed for speech over the internet, so it stays intelligible at very low bitrates, which is also why those files are tiny.
Upload them directly. Short voice messages fit easily within the free plan, and the transcript shows when each sentence starts, which helps with long rambling messages.
When you'd still convert OGG to MP3
Only when a different app needs MP3, for example an older car stereo, a podcast host or a media player that doesn't read OGG. For transcription it isn't necessary.
The free OGG and Opus converters on this site turn files into MP3 or WAV inside your browser, without uploading them anywhere.

Frequently asked questions
Is OGG to text free?
Yes. Files up to 30 minutes are free without an account, up to 120 minutes per month.
Can I upload .opus files?
Yes. Opus files are accepted directly, whether they end in .opus or .ogg.
Do I need to convert OGG to MP3 first?
No. Convert only if another app needs MP3; the browser converter on this site does it without uploading.
Will low-bitrate voice messages transcribe well?
Opus keeps speech intelligible at low bitrates, so clear voice messages usually transcribe well. Background noise and wind affect the result more than the bitrate.
Are my voice messages private?
They're never used to train models and are deleted after the retention period you choose.
