By uploading a file you agree to our Terms of Service and Privacy Policy.

How to convert a WAV file to text

Pick the WAV from your device: a field recorder file, an export from an audio editor, a dictation or a recorded call all go in the same upload box. The upload is resumable, so a dropped connection picks up where it left off instead of starting over, which matters for a large uncompressed file. After the upload, the WAV waits in the transcription queue and the page shows your place in it with an estimated wait.

The transcript then appears on this page. Each line has a timestamp, and when the recording has more than one voice, each line also says which speaker it belongs to. There is nothing to set up first: no engine to choose and no options to adjust.

WAV file size and the free limit

WAV is uncompressed, so a WAV is several times larger than an MP3 of the same recording.A CD-quality stereo WAV of a full 45-minute recording is about 476 MB, under the 1 GB limit. Studio files recorded at 24-bit or a high sample rate grow much faster; if yours is too large, export the recording as FLAC (lossless, smaller) or MP3 from your audio editor and upload that file instead.

The free tool uses the same transcription pipeline as the paid product. Your audio is never used to train AI models, and per-language accuracy is published openly on our benchmarks page.

Free limits for WAV files

One free transcription per day, shared across all free tools. The WAV can run up to 45 minutes and be up to 1 GB. Timestamps, speaker labels and automatic language detection across 52 languages and dialects are included. Free transcripts are deleted automatically about 24 hours after they finish, so copy the text out or sign up to keep it.

A free account raises the length limit and adds signup credit, exports (TXT, SRT, VTT and more), a searchable library of your recordings, and cited answers to questions about them. Pricing has the details.

More free tools

MP3 files have their own free MP3 to text converter, any other audio format works in the free audio to text converter, and a recording made on a phone has the free voice memo to text converter. The free interview transcription tool page is written for conversations with several people. All of them are collected on the free tools page.

Frequently asked questions

How do I convert a WAV file to text?

Pick the WAV from your device using the upload box on this page. The file joins the transcription queue as soon as the upload finishes, and the transcript appears on this page when it is done, with a timestamp on every line and speaker labels when more than one person talks.

Is there a WAV file size limit?

Yes. The free tool takes audio files up to 1 GB and 45 minutes long. A CD-quality stereo WAV of a full 45-minute recording is about 476 MB, under the 1 GB limit. A 24-bit or high sample rate studio WAV can go over it; export the same recording as FLAC or MP3 and upload that instead.

Does a WAV give a better transcript than an MP3?

A WAV is lossless, so nothing is thrown away, and it is a perfectly good file to upload. For speech, a well-encoded MP3 or FLAC of the same recording is usually just as clear. How the recording was made matters far more: a microphone close to the speaker and a quiet room.

Is this WAV to text converter really free?

Yes. One WAV a day, up to 45 minutes long, with no account and no card. The daily allowance is shared across all the free tools. A free account adds signup credit and longer file limits.

Which languages can it transcribe?

It transcribes speech in 52 languages and dialects and detects the language on its own, so there is no language menu to set before you upload the WAV.

What about recordings longer than the free limit?

The free tool stops at 45 minutes, and a longer WAV is turned away before it uploads. Sign up free to transcribe it: an account comes with signup credit, much higher length limits, exports (TXT, SRT, VTT and more), and a searchable library of everything you transcribe.
