Convert MP3 to SRT

Upload a MP3 file and get SRT subtitles in minutes. MP3 is the most widely used compressed audio format, produced by almost every recorder, podcast tool, and phone app.

SRT is the standard subtitle format accepted by YouTube, Vimeo, LinkedIn, video editors, and every major video platform — each cue is numbered and timed to the audio. Jackob.ai transcribes the audio with AI — including podcasts, interviews, voice memos, and phone recordings — and every upload can also be exported as DOCX, PDF, TXT, SRT, or VTT, so one transcription covers all your outputs.
