Convert SRT to VTT, or VTT to SRT
Convert SRT to WebVTT for a web player, or convert VTT to SRT for an editor that expects it. Choose a UTF-8 subtitle file up to 2 MiB or paste its text. The browser keeps the words and timing, and warns if styling or positioning will be lost. Review the preview before you download.

Worked subtitle example
The same three cues keep their text and timing. The WebVTT copy adds the WEBVTT header and uses periods before milliseconds.
1 00:00:02,000 --> 00:00:04,500 Keep the original subtitle file. 2 00:00:05,000 --> 00:00:07,250 Check timing in your final player. 3 00:00:08,000 --> 00:00:10,000 Download the reviewed copy.

What this tool reads
One UTF-8 SRT or WebVTT text file up to 2 MiB and 20,000 cues, with timestamps below 100 hours. Empty cues, invalid times and out-of-order starts need correcting before export. Overlaps are kept with a warning. Streaming timestamp maps are not supported.
Processing runs in this browser without uploading subtitles or downloading a speech model. The workspace has no saved history. The site still loads application resources; optional analytics and submitted feedback follow the Privacy Policy.
Common questions
Is renaming .srt to .vtt enough?
No. WebVTT needs a WEBVTT header and period-separated milliseconds. This tool parses the cues and writes the selected format; it does not just rename the file.
Does conversion keep all formatting?
No. This converter produces basic text and timing. It removes styles, positions, notes, cue identifiers and inline timestamp markup when present. Voice labels become ordinary text. Check the warnings and preview.
Does it change timing or improve recognition?
No. Format conversion preserves parsed start and end times. It does not correct transcription errors or synchronize captions with a recording.
