The Auto Subtitle Generator tool lets you automatically generate subtitles for your video or audio file. You can edit the subtitles and their style, download the edited subtitles as an SRT or TXT file, and embed them into a video.
Please note that we only do hard subtitles. Hard subtitles are burned in, or hard-coded, as an overlay over your video and cannot be turned off or on later in a player.
Refer to this article to see the list of supported formats.
Add video or audio

Auto-generate subtitles
To generate subtitles automatically, click the Auto subtitles button (this option is only available for registered users and for files with speech only). Select the original language of the video and click Generate.
To achieve a more accurate generation of subtitles, make sure the audio track in your video or audio has good quality and minimal background noise, no overlapping speech or multiple languages being spoken, and that you have chosen the correct language/accent option.
