How to mp3 to srt
- 1
Upload your MP3 file
Drag your MP3 into CentClip or click to browse - no account required to get started. Any standard MP3 works, whether it is a podcast episode, recorded interview, lecture, or audio extracted from a video project. Your first 5 minutes of audio are processed free.
- 2
Select your spoken language
Choose the language spoken in your recording from over 50 supported options so the engine can recognize words accurately and build correctly timed subtitle blocks. CentClip transcribes what was actually said - it does not translate - so the SRT output matches the language in the file exactly. Subtitle timing is segmented automatically based on natural speech pauses.

Download your SRT file
When processing finishes, download your SRT file ready to import into any video editor, upload to YouTube, or hand off to a client. You can also grab a VTT file for web video players, a plain text transcript, or an MP4 with captions burned directly into the picture if you need a finished output with visible subtitles.
Why choose CentClip?
Timestamps that line up with spoken words, not just sentence boundaries
The core challenge of converting MP3 to SRT is getting subtitle timing that feels natural on screen - not blocks that appear too early or hang on screen too long. CentClip segments speech at clause boundaries and timed pauses rather than chopping by character count, so each subtitle line appears and disappears in sync with what the speaker is actually saying. Editors who previously hand-timed SRT files from audio report cutting the correction pass from hours to a few minutes. The SRT imports cleanly into Premiere Pro, DaVinci Resolve, CapCut, and Descript without manual re-timing.
Pay per file, not per month - useful for irregular workloads
Podcast producers, corporate trainers, and freelance transcriptionists rarely have a consistent weekly volume of MP3 files that justifies a $20-30 monthly subscription. CentClip charges 5 cents per minute of audio and nothing else - no seat fee, no idle months billed, no annual commitment. Credits never expire, so you can buy a block before a large batch of recordings and use the remainder on the next project months later. That model fits the way most MP3 subtitle work actually arrives: in bursts, not on a schedule.
One upload produces every subtitle format your project might need
An MP3 often ends up in multiple downstream contexts - the same interview might become a YouTube video needing SRT captions, a podcast episode needing a plain text transcript, and an accessibility-compliant web video needing a VTT file. CentClip produces all three from a single transcription job at no extra cost. You are not re-uploading the file or paying again to get a different format - every output is available from the same results page the moment processing completes.
FAQ
How accurate is the MP3 to SRT conversion?
Accuracy depends on recording clarity and speaker accent, but CentClip performs well on typical MP3 recordings from interviews, podcasts, and lectures. Clear speech in a quiet environment regularly exceeds 95% word accuracy, and subtitle timing is generated automatically without manual adjustment.
Is there a free trial and what does it cost after that?
Your first 5 minutes of audio are free with no account required. After that, transcription costs 5 cents per minute - there is no subscription, no monthly fee, and credits never expire.
What formats does CentClip accept and where can I use the SRT output?
CentClip accepts MP3 as well as most common audio and video formats including MP4, WAV, M4A, MOV, and WebM. The SRT output is a standard file compatible with YouTube, Vimeo, Premiere Pro, DaVinci Resolve, CapCut, and any other tool that reads subtitle files.
Do my credits expire if I do not use them right away?
No - credits never expire. Buy them when you have a project and use whatever remains on your next job, whether that is a week or a year later.
