Export
Download SRT/VTT free, or an MP4 with captions burned in.
Burned in or as a file
Burned-in (open) captions are part of the video and show everywhere. Subtitle files (closed captions) can be turned on and off on YouTube and in most players. You can do both.
No editing software needed
Skip the timeline in Premiere or CapCut. Captions are generated, timed and styled automatically, and you can still fine-tune every line.
FAQ
Frequently asked questions
How do I add subtitles permanently to a video?+
Upload your video, check the captions, then choose Export MP4. The subtitles are burned into the video frames, so they show on any platform or player.
Is it really free?+
Yes. You can transcribe up to 30 minutes a day, edit your captions and download SRT, VTT or TXT files for free with no watermark. Exporting a video with burned-in captions is free at 720p with a small watermark; paid plans unlock 1080p, 4K and no watermark.
Which file types can I upload?+
MP4, MOV, WEBM and MKV videos, plus audio files like MP3, WAV and M4A. Free accounts can upload videos up to 10 minutes long.
Is my video uploaded to your servers?+
No. Your video is processed entirely in your browser. Only a compressed audio track is sent for transcription, and it isn't stored afterwards.
