mp3totext.net is a free browser-based online audio-to-text tool whose main purpose is to convert speech in audio files such as MP3 into editable, exportable text. Users do not need to install any software; they simply upload an audio file to begin conversion, making it suitable for people who want to quickly obtain transcripts, subtitles, or notes.
Main capabilities
- Audio-to-text: After uploading an MP3, the tool automatically starts speech recognition and converts speech to text. Short audio usually completes within seconds, while longer recordings take more time.
- Multi-format support: In addition to MP3, it also supports common formats such as M4A, WAV, FLAC, and AAC, so users do not need to convert formats in advance.
- Built-in editor: After conversion is complete, results can be viewed in the browser's built-in editor and minor errors can be corrected.
- Export options: Transcripts can be exported as TXT files, and subtitles can also be exported as SRT files, making them convenient for podcasts, blogs, subtitles, and research notes.
- AI punctuation and paragraphing: AI automatically adds punctuation and organizes long audio into paragraphs, making it easy to skim and edit later.
How to use
- Upload a file: Drag and drop an MP3 into the upload box, or click the upload button to select a file. Formats such as M4A and WAV are supported.
- AI transcription: The speech recognition engine automatically processes the audio, and the transcript appears progressively in the browser.
- Edit and export: Check and correct the results in the editor, then export as TXT or SRT.
