Burn VTT subtitles into video — browser-based, free

Preserves VTT positioning cues · Works with MP4, WebM, MOV inputs · 100% local browser processing

VTT (WebVTT) is the modern, HTML5-native subtitle format used by HTML5 video players, YouTube, and many streaming platforms. Unlike SRT, VTT supports styling cues, positioning, and CSS. BurnSub takes your VTT file and renders the captions directly into your video frames so they show up on any platform — including those that ignore VTT tracks during upload.

Frequently asked

What is the difference between VTT and SRT?

SRT is a simple timecode + text format. VTT (WebVTT) is its modern web-native successor — it adds positioning cues, styling hints, and CSS support. Both work fine in BurnSub.

Will VTT styling carry over?

BurnSub respects positioning cues (top/bottom/left/right) from your VTT, but rendering style (font, color, weight, animation) comes from the BurnSub preset you select. This gives a consistent look.

Does this work with YouTube VTT exports?

Yes. Export your VTT from YouTube Studio, drop the video and VTT into BurnSub, and burn — your captions are now permanent in the file.

Can I burn VTT into a WebM file?

Yes — input WebM is supported. Output container can be MP4 or WebM depending on your target platform.

Is anything uploaded?

No. Video and VTT both stay in your browser. Verify in DevTools → Network tab — you will see no outgoing requests during the burn step.
