Burn Subtitles into Video

Upload your own SRT subtitle file and a video. Burn subtitles into the video offline — no transcription needed.

What can you use this for?

Multilingual subtitles

Translate your SRT file into another language and burn bilingual subtitles — original on top, translation below.

Social media captions

Burn captions directly into the video so they display on muted autoplay on Instagram, LinkedIn, and Facebook.

E-learning & courses

Permanently embed subtitles into course videos so learners always see text, even in offline or LMS players.

Accessibility

Hardcode subtitles to ensure hearing-impaired viewers can follow along regardless of the platform or player.

Film & video production

Lock in subtitles for final delivery files when clients or distributors require hard-coded text in the video file.

Repurpose existing SRT files

Already have an SRT from YouTube or another tool? Burn it into any video file without re-transcribing.

1

3

Style and export

Pick a font, size, color, and position, then export an MP4 with the subtitles permanently burned in.

Which subtitle formats are supported?

SRT and WebVTT (.vtt) files are supported. ASS/SSA files need to be converted to SRT first.

Will the video lose quality?

The output keeps your original resolution. The video is re-encoded once to draw the subtitles onto each frame.

Is my video uploaded?

No. Your file never leaves your device — processing runs locally in the browser using WebCodecs.

Do I need subtitles first?

Yes. If you don't have a subtitle file yet, use the Video to SRT tool to generate one from your video with AI.
