How this free audio-to-text tool works
- Upload an audio file or paste a direct audio URL.
- Pick Speed or Best Quality, then start transcription.
- Read the transcript in-page, copy it, or import to Wisprs for AI summaries and exports.
The free flow runs Whisper-based models with automatic language detection across 100+ languages, so there is nothing to configure before you upload.
Supported formats and limits
Supported formats: MP3, WAV, M4A, OGG, WEBM, FLAC. Free usage covers files up to 10 minutes and 500MB, with free TXT and SRT exports. Richer exports like DOCX, VTT, and JSON come with the Pro, Studio, and Agency plans. For long-form files, speaker workflows, and reusable content operations, use meeting transcription software and podcast transcription workflows.
What you can expect from the free flow
The free version is built for short files, quick checks, and occasional use rather than heavy production. Most short recordings finish within a few minutes, depending on queue load and the mode you choose. Speed mode returns results faster with slightly lower accuracy, while Best Quality takes a little longer but produces cleaner text.
A few tradeoffs are worth knowing. The free tier has no speaker labels, so multi-speaker recordings arrive as a single block of text, and exports may carry a small watermark. You get excellent accuracy on clear audio, while results vary by language, accent, and recording quality.
When it makes sense to upgrade
Upgrading pays off when transcription becomes part of your regular workflow rather than a one-off task. Speaker identification is the biggest single win for interviews, meetings, and multi-voice podcasts, since Wisprs separates speakers automatically and saves real editing time on longer recordings.
Paid tiers also add export formats like DOCX, VTT, and JSON, higher-tier engines, and batch processing for many files at once. If you are comparing tools first, the free version is a realistic preview of speed and baseline quality. Compare what each tier adds on pricing.
FAQ
Does it support MP3 and WAV files?
Yes. MP3 and WAV are fully supported, along with M4A, OGG, WEBM, and FLAC. You do not need to convert files first — just drop in whatever recording you already have and start transcription.
How accurate is audio to text conversion?
You get excellent accuracy on clear audio, and results vary by language, accent, and recording quality. Best Quality mode usually improves results, and you can edit the transcript before exporting.
Can it identify different speakers?
Not on the free tier. Speaker identification (diarization) is available on paid plans that route audio through higher-tier engines — usually the main reason teams move up from the free flow.
What if my file is longer than 10 minutes?
Use Wisprs for long-form transcription with speaker detection, timestamps, and higher-quality workflows.
Can I export and summarize this transcript?
Yes. Use “Extract AI Summary on Wisprs” to continue with summaries, searchable transcript workflows, and export-friendly processing.
