Convert audio to text online
Upload a recording up to 2 GB - a voice memo, interview, lecture, or meeting - and IronMemo converts it into accurate, speaker-labeled text with timestamps. Every language is routed to the speech model that wins our benchmark for it, transcription minutes are not metered on the free plan, and you also get an AI summary with action items.

How to convert audio to text
Three steps - no installs, no format juggling.
Upload your audio
Drag the file into the browser - MP3, M4A, WAV, OGG, OPUS, MP4, or WebM, up to 2 GB. A phone memo and a three-hour lecture go through the same door.
The right model does the work
Your audio is routed to the speech model that wins our benchmark for its language - that is how accuracy stays high outside English too.
Get editable text
In minutes you have a transcript with speaker labels and timestamps, plus an AI summary with action items - ready to correct, search, or share.
Typing it out vs converting it
Both get you text. They differ in what it costs you.
You transcribe by hand
- Playback plus constant rewinding - manual transcription takes several times the length of the recording.
- Speaker changes, crosstalk, and fast passages are easy to mis-attribute or lose entirely.
- No timestamps unless you add them yourself, so finding a quote later means re-listening.
- The result is raw text - the summary and the to-do list are still on you.
You convert it with IronMemo
- A multi-hour file converts in minutes, and the free plan does not meter transcription minutes.
- Speakers are separated automatically, and every line carries a timestamp back to the audio.
- 30+ languages with per-language model routing - including recordings that switch languages mid-sentence.
- You also get an AI summary and action items, not just a wall of text.
To be fair: for certified legal transcripts or broadcast-ready subtitles you may still want a human pass at the end. For notes, quotes, search, and summaries, automatic conversion is the pragmatic default.
Free limits: IronMemo vs typical converters
Most free tiers meter minutes or cap file length. Ours is set up the other way around.

|---|---|
| IronMemo | Files up to 2 GB, transcription minutes not metered |
| TurboScribe | 3 files per day, 30 minutes each |
| Notta | 200 minutes per month, 5 file uploads |

Competitor limits verified in July 2026 against the public pricing pages of turboscribe.ai, notta.ai, and happyscribe.com. Plans change - re-check before you rely on them.
What the converter returns
Structured text you can actually use - not a wall of words.
Editable transcript
Speaker-labeled text with timestamps - fix a word, search a phrase, or jump to the exact second it was said.
AI summary with action items
Key decisions and to-dos extracted automatically, each linked back to the moment in the recording.
A searchable archive
Converted recordings land in one workspace - ask questions across all of them or export what you need.
One converter for audio and video alike: MP3, M4A, WAV, OGG, OPUS, MP4, WebM and other common formats.
Numbers that matter when the file is real
Clip-length demos are easy. Long, messy, multilingual recordings are the actual test.
2 GB
max file size
A two-hour interview as uncompressed WAV still fits - no cutting the file into parts.
30+
languages
Per-language model routing keeps accuracy high beyond English, and mixed-language audio is handled.
0
minute caps on free
Convert whole recordings, not slices - the free plan does not meter transcription minutes.
