Add Subtitles to Video
Burn SRT or VTT subtitles permanently into a video, with your choice of font size and style.
Common questions
How does Add Subtitles to Video work?
Choose a video, then choose an .srt or .vtt subtitle file — the tool tells you how many cues it parsed. Adjust font size, colour, outline or background box and the bottom margin, scrub the preview to check a line, then press Burn subtitles.
Can I trust the output for production?
Nothing is uploaded. The video, the subtitle file and the render all stay in your browser, decoded and re-encoded locally with WebCodecs.
Will this tool stay free?
Free, with no sign-up and no limit on how many videos you process.
