What is the Subtitle Maker?
Subtitles make videos accessible and boost watch time – most social videos are watched without sound. Load your video (it stays on your device), paste your script split into lines, then play the video and tap “Mark” at the start and end of each line. Fine-tune any timing, preview the captions over the video and download an .srt or .vtt file for YouTube, Facebook, Premiere, CapCut or VLC.
How to use the Subtitle Maker
- Load a video and paste your script (one caption per line).
- Play and tap Start / End (or press S and E) for each line.
- Check the preview, adjust times, and download SRT or VTT.
Caption tips
- Keep each caption to 1–2 short lines (about 42 characters per line).
- Show each caption for 1–6 seconds.
- Upload the SRT in YouTube Studio → Subtitles.
This Subtitle Maker is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
