How do I convert an MP3 to SRT?

Upload the MP3 on this page, sign in with Google, choose the spoken language (or auto detect), click Generate in the Audio Transcription workspace, and download the SRT file. Everything runs online — no software to install.

Can I convert other audio formats to SRT?

Yes. M4A, WAV, OGG, Opus, AAC, and FLAC files are accepted as long as your browser can decode them. MP3, M4A, and WAV work in every modern browser.

How accurate are the timestamps?

Cues are built from word-level timestamps returned by the speech recognizer, so each line typically starts within a fraction of a second of the spoken words. You can fine-tune any cue in the editor before downloading.

Is there a length or size limit?

Each audio file can be up to 30 minutes long and up to 500 MB. Split longer recordings into parts before uploading.

How much does MP3 to SRT cost?

Transcription uses 1 credit per second of audio. New accounts receive 300 free credits (about 5 minutes); after that you can buy credits or subscribe. Re-translating an existing transcript does not use extra credits.

Do you store my audio files?

No. The file is decoded in your browser and only the audio needed for speech recognition is sent for processing. We don't keep your recordings or build a media library from them.

How MP3 to SRT conversion works

Your MP3 is decoded in the browser, the speech is transcribed with word-level timestamps, and the words are grouped into readable SubRip cues — each with a number, a start and end time, and a short line of dialogue.

Step 1
Upload your MP3
Choose an MP3, M4A, WAV, or OGG file up to 30 minutes and 500 MB. New users get 300 free credits (~5 minutes).
Step 2
Transcribe with timestamps
Speech recognition converts the audio into numbered cues with start and end times. On credit plans, transcription costs 1 credit per second of audio.
Step 3
Download the .srt
Edit lines if needed, optionally translate into 40+ languages, then download SRT — or VTT and TXT from the same result.

What does “MP3 to SRT” mean?

An MP3 to SRT converter listens to the speech in an audio file and writes it out as a SubRip subtitle file. Instead of one long block of text, you get short numbered cues with timestamps such as 00:00:04,300 --> 00:00:07,800, so every line knows exactly when to appear.

That makes SRT the right output when audio is going to be paired with picture: a podcast published as a YouTube video, a voice-over for a slideshow, a narrated course, or an interview you are cutting in an editor. If you only need readable text, the same workspace also exports a plain TXT transcript.

Why export SubRip (.srt) from audio

SRT is the most widely accepted caption format, so one file works almost everywhere you publish.

• YouTube, Vimeo, Facebook, and LinkedIn accept .srt uploads as captions.
• Premiere Pro, DaVinci Resolve, Final Cut Pro, and CapCut can import SRT onto the timeline.
• Plain text with comma-millisecond timestamps — easy to fix in any text editor.
• Need WebVTT for an HTML5 player? Download VTT from the same transcript.

MP3 to SRT features

Built for people searching “mp3 to srt” or “audio to srt” who need a timed subtitle file, not just a transcript.

Word-level timing

Cues are built from word timestamps, so lines start and end close to the actual speech instead of drifting.

Auto language detection

Leave the source on auto, or choose from English, Spanish, Chinese, Japanese, and more for better accuracy.

Fix a word, adjust timing, or merge and split cues in the editor, with undo and redo.

Your audio stays private

The file is decoded in your browser, only short audio segments are sent for speech recognition, and we don't store your recording.
