Subtitles are stored in many formats, and not every video player or editing app reads them all. WebVTT (VTT) and Advanced SubStation Alpha (ASS) are two common subtitle formats with different structures. This converter parses your .vtt file, keeps the timing and text of every caption, and rewrites the content as a valid .ass file. The whole conversion runs locally in your browser, so your subtitle content stays private.
Yes. This tool is completely free and has no usage limits, watermarks or sign-up requirements.
No. The conversion runs entirely in your browser, so your VTT file never leaves your device.
Upload or paste your .vtt file, review and edit the converted ASS output, choose a format from the dropdown if you want a different one, then click Download.
Yes. Every caption keeps its original start and end time during conversion, so the new ASS file plays in sync with your video.
