Is an OGG file lossless?
It depends on what is inside. Wikipedia says the audio layer is most often Vorbis or Opus, both lossy, while FLAC and OggPCM in the same container are lossless.

In short
Upload the OGG and get the words as text: one line per segment, the time it starts and ends, and the speakers named on request. OGG is a container, not a codec — a file is up to 30 minutes, and the free plan is $0.
How to transcribe an OGG file
- 1
Upload the file as it is
The widget accepts ogg, and there is nothing to convert first. What the transcript is made of is the audio stream inside the container.
- 2
Set the language, split the voices
Rthe recording language is detected automatically. Switch on the split by speaker when the recording holds two people, so every line stays attributable.
- 3
Export the finished text
One line per segment, with the time it starts and ends. Take it away as plain text, Markdown, SRT, VTT or CSV on any plan, and DOCX on the Pro plan.

What is inside an OGG file
| What | Value |
|---|---|
| The format | a multimedia container maintained by the Xiph.Org Foundation |
| The licence | free and open, unrestricted by software patents |
| The audio inside | usually Vorbis or Opus; the lossless FLAC and OggPCM fit as well |
| The extensions | .ogg for Ogg Vorbis and .oga for audio-only files, recommended since 2007 |
| The file | audio and video are both accepted: mp3, wav, m4a, mp4, webm, ogg, flac, aac, wma, mov |
The case
A box, not a sound
An OGG file is a box, not a sound. The container is maintained by the Xiph.Org Foundation and is free of software patents; what sits inside is usually Vorbis or Opus, and sometimes FLAC or OggPCM. So the extension says very little about the audio — and the transcript is made from the audio, whatever the box holds.
Tips
An .ogg file from a recorder can be transcribed as it is.
Check what is inside if the file sounds different.
The .oga extension is the same container as .ogg.
Export CSV when the times have to go into a sheet.
Questions this page answers
Which extension should an audio-only file have?
Xiph.Org recommends .oga for audio-only files and .ogg only for Ogg Vorbis, since 2007. The name says nothing about the audio inside the container.
Can an OGG hold a video?
Yes, the container can multiplex audio, video, text and metadata. For a transcript only the audio stream matters, and the picture is left alone.
How much does it cost?
The free plan is $0 with 3 files a day and up to 30 minutes per file, no card. Pro is $10 a month paid yearly, or $20 a month paid monthly.
