Frequently asked questions
- How do I generate subtitles for a YouTube video?
Upload your video to AutoSubtitles, let the AI transcribe the audio, edit the text and timing, then download an SRT file to upload in YouTube Studio, or export a video with captions burned in.
- Can I upload the subtitles to YouTube?
Yes. AutoSubtitles exports standard SRT files, which you can upload directly to your video in YouTube Studio so viewers can toggle captions on or off. Prefer captions that are always visible? Export an MP4 with them burned in instead.
- Why not just use YouTube's automatic captions?
YouTube's automatic captions are a fair start, but you fix them inside YouTube Studio, you can't style them, and they stay on YouTube. With AutoSubtitles you correct the text before publishing, then upload a clean SRT or burn styled captions into the video so they show wherever it's posted.
- Can I add captions to YouTube Shorts?
Yes. Upload the vertical 9:16 video, pick one of the 28 caption styles, including animated word-by-word ones, and export it with the captions burned in. They read on mute and stay on the video if you also post it to TikTok or Reels.
- Can I translate my YouTube subtitles?
Yes. On the Pro plan you can translate subtitles into 30+ languages to reach an international audience.
- Is the YouTube subtitle generator free?
Yes, with no signup. The free plan includes the full editor and every caption style, and exports videos up to 10 minutes long at up to 720p with a small watermark. Pro ($9/month) adds SRT, VTT and TXT downloads, no watermark, HD and 4K export, and translation.
