Free transcription: audio to text online without paying anything (and where free actually breaks)

The "free" cluster, mapped

There is a giant cluster of search phrases asking some version of the same question — "is there a free way to transcribe my audio?" — and the cluster is wide enough to be worth naming explicitly: "free transcription audio to text online," "transcribe audio to text free online," "free audio to text online," "free transcription audio to text," "transcribe audio file to text free online," "transcribe online audio to text free," "transcribe audio to text free online," "automatic audio transcription free," "auto transcribe audio free," "free online speech to text transcription," "online transcribe audio to text free," "transcribe interview audio to text free," "free convert mp3 to text," "websites that transcribe audio for free," "audio to text online free unlimited," "speech to text free online converter," "speech to text free online," "free transcription audio free," "transcription audio free," "free audio to text online," "from audio to text online free," "free video to text transcription," "audio to text online free unlimited," "transcribe online audio to text free."

Every one of those phrases is asking the same question. The answers fall into three groups: things that are genuinely free, things that are free up to a limit, and things that are free as a hook to upsell. We will name examples of each and explain how to know which group a tool is actually in before you upload an hour of sensitive audio.

Genuinely free options

These six are the answer to "websites that transcribe audio for free" and "automatic audio transcription free" if your priority is "no money ever." None of them are great at multi-speaker audio without extra setup; if you are doing interview transcription or meeting notes, the answer changes.

Free up to a limit (the honest free tiers)

Most cloud SaaS transcription tools have a free tier — usually 30 to 180 minutes per month. That answers "online speech to text converter free" and "speech to text free online converter" and "from audio to text online free" honestly: yes, free, but capped. After the cap you pay or wait until next month.

• TigerScribe — 180 free minutes/month, no credit card, auto-deletes in 30 days. Diarization included.
• Otter.ai — 300 free minutes/month, 30 min per recording. Diarization included.
• Notta — 120 free minutes/month, 3 min per recording.
• Sonix — 30 free minutes one-time. Then pay-per-minute.
• Trint — 7-day trial. No permanent free tier.

For "free transcription audio to text online" without strings attached — pick one of the genuinely-free options above. For "free transcription audio to text" with quality diarization and an actual modern UI — the cloud free tiers are the better answer; you just have to live with the monthly cap.

Free as bait (avoid)

A subset of "free transcription audio to text online" sites are SEO bait: they promise free transcription, then either watermark the output, lock the export behind a paywall, or train models on your audio in exchange for the "free" service. The tells are usually obvious: no privacy policy, no company name in the footer, "transcribe for free" with no minute cap stated, ads everywhere. If the tool will not name its retention or training policy on the front page, assume it is the product and your audio is the input.

Free by source format

Some "free transcription audio to text" queries get more specific about format. "Free convert mp3 to text" wants MP3 specifically. "Free video to text transcription" wants video. "Mp4 speech to text" wants MP4. "Video speech to text" is the same. The format does not actually matter much for modern tools — they accept everything common — but it changes which tools surface in search:

• Free convert mp3 to text — every cloud tool with a free tier handles MP3 natively.
• Free video to text transcription — same tools, plus YouTube auto-captions if the video is yours and uploadable.
• Mp4 speech to text — same tools again; MP4 audio track is extracted server-side.
• Video speech to text — for "the speech inside a video," strip the audio with ffmpeg or upload the video directly. Either works.

When "free" matters less than "private"

For some recordings — interviews under embargo, therapy sessions, legal discovery, internal HR conversations — "free" is the wrong axis. The right axis is "what happens to my audio after I upload it?" In that case, "transcribe interview audio to text free" is asking the wrong question; the right question is "transcribe interview audio with a stated retention window and no training-on-my-data policy." That narrows the field considerably and rules out most of the SEO-bait sites.
