ASS to VTT converter

How to convert ASS to VTT

1. Open the ASS file. Click Open subtitle file or drop your .ass file onto the tool. You can also paste the text.
2. Choose VTT. “WebVTT (.vtt)” is preselected in the Save as menu.
3. Fix anything else (optional). Shift or sync the timing, repair the encoding or clean up overlaps before saving.
4. Download. Click Download to save the .vtt file in UTF-8, or Copy to paste it elsewhere.

What changes when you convert ASS to VTT

Browsers cannot render ASS, so web players need WebVTT. The converter keeps the text and timing of every Dialogue line, turns \N into line breaks and converts italic, bold and underline to WebVTT tags. Fonts, outlines, colors, karaoke and vector drawings are removed.

Lines aligned to the top of the screen ({\an7}, {\an8}, {\an9}) are given the cue setting line:0 so signs stay out of the way of dialogue. Times move from centiseconds to milliseconds without any change in value.

If you need the exact look of the original ASS on the web, render it into the video instead (hard subtitles) — WebVTT styling is far more limited.
