In short

An MP3 becomes an SRT file: numbered blocks, a start time, an end time, the spoken words. Send the recording to the widget and the subtitle file comes back ready for a player or an editor. The free plan is $0, with 3 files a day.

How it works

How to turn an MP3 into an SRT file

  1. 1

    Hand over the recording

    The widget takes the audio as it comes: mp3, wav, m4a, ogg, flac, aac, wma. One file is up to 30 minutes at the most; the free plan allows three files a day, 30 minutes each.

  2. 2

    Look at the first blocks

    Every block carries its number, the second it starts, the second it ends and the words. A name attached to a line is the part most worth checking before you export.

  3. 3

    Download the .srt file

    The button under the result hands you a file with the extension .srt, ready to drop next to the video or to load into the subtitle menu of a player.

  4. 4

    Watch the timecodes

    The milliseconds are written with a comma, 00:00:02,000. Check the first minute against the recording before the subtitles go out.

The format

What an SRT file is, and what we make of it

The SRT file itself

numbered blocks, each with a start and an end time and the text under it

The timecode

00:00:02,000 — a comma before the milliseconds

The character encoding

no official standard; the file is often written in Windows-1252, and YouTube accepts only UTF-8

Who reads it

most video players and subtitle tools

The case

What the SRT format does not decide for you

A subtitle file is a list of moments, and the SRT keeps that list in the plainest possible shape: a number, a time, another time, the words, and a blank line that closes the block. Nothing is hidden inside it: the file is plain text with the timings, so a player or an editor reads it as it is.

Tips

  • Check the first minute of the transcript before you export it.

  • Short lines read better than long ones on a phone.

  • Keep the file in UTF-8 — that is what the web expects.

  • One recording per file; split a long one before uploading.

Questions this page answers

What is inside an SRT file?

Numbered blocks. Each one holds a line with the start time, an arrow, the end time and the text of the subtitle; a blank line ends the block.

Why do some players show odd characters?

The format has no official character encoding, so a file written in one code can be read in another. Our export is UTF-8, which is what the web expects.

Is the subtitle export free?

Yes, the export costs nothing on the free plan: $0, three files a day and 30 minutes per file. The list of formats is TXT, Markdown, SRT, VTT and CSV, with DOCX on Pro.

Can I make subtitles for a video as well?

Yes. Upload the video file instead of the sound and the same blocks come out of it, with the same start and end times for every line.
