MP3 to text: how to transcribe .mp3 files on iPhone

You have a podcast episode, an old recorder’s file, or a downloaded audio — and you need the words in it as text. You don’t need a converter, an mp3 tool, or a desktop app: transcription apps accept .mp3 directly.

Short answer: Import the file into AI Transcribe — tap Import, choose Audio File, pick your .mp3 file — and the transcript appears with timestamps and speaker labels. Files up to 3 hours are supported, and the format is converted internally, so no preparation is needed.

What is a .mp3 file?

MP3 is the most widely used compressed audio format — podcasts, downloads, older dictaphones and Android recorders all produce it. Every transcription pipeline accepts it.

MP3 to text, step by step

1. Get the file onto your iPhone (Files, Downloads, or shared from another app).
2. Open AI Transcribe and tap Import → Audio File.
3. Select the .mp3 file. It’s converted and transcribed automatically — keep the app open while it processes.
4. Use Summarize or any of the 15+ AI tools on the result, or export the transcript as text or PDF.

Frequently asked questions

Do I need to convert .mp3 to another format first? No. Conversion happens inside the app; any common audio format works.

How long can the file be? Up to 3 hours per file. Transcription takes minutes, not the file’s duration.

Which languages are supported? 32 languages with automatic language detection — the file’s language doesn’t need to be set manually.

What does it cost? AI Transcribe is free to download and try; the Pro subscription (weekly or annual) unlocks up to 3 hours of transcription per day.
