Frequently asked questions
What is an SRT file?
SRT (SubRip Subtitle) is a plain-text subtitle format: a numbered list of cues, each with a start and end timecode and the words spoken in that window. Its simplicity is why it became the most widely supported caption format.
Where does the SRT file work?
Almost everywhere — upload it alongside a video on YouTube, import it into editors like Premiere Pro, Final Cut Pro, or DaVinci Resolve, load it in players like VLC, or attach it to lessons on course platforms.
Is it really free?
Yes — converting audio to SRT is free for files up to 5 minutes, with no signup. For longer recordings, AI summaries, and more exports, create a free account.
Can I convert video as well as audio?
Yes. Upload MP3, M4A, WAV, AAC, FLAC, MP4, MOV, or WEBM — whether it's an audio track or a full video, the spoken audio is transcribed and timed the same way.
Is my file stored anywhere?
No. Your file is sent for transcription and is not retained on our servers.
Need more?
A free account unlocks 25-minute files, AI summaries, and export to TXT, SRT, and VTT — enough to subtitle full episodes and lectures.
