Choose the right destination format

Use SRT for broad compatibility, WebVTT for web playback, ASS/SSA when styling matters, and text/data formats when you need dialogue or structured data.

Review format differences before export

Some subtitle formats cannot represent the same styling, positioning, identifiers or metadata. The preview and fidelity notes make those differences visible before download.

How to use this tool

  1. Choose a subtitle file.
  2. Select the operation and review cue diagnostics or loss warnings.
  3. Preview the result, then export if this operation provides an output.

Questions about this tool

Can this generate subtitles from a video?

No. It converts an existing subtitle file. Use Extract Embedded Subtitles for a video that already contains text subtitle tracks; speech recognition is a different workflow.

Do my files or text leave this device?

Your source content is processed in this browser, not uploaded for processing. The browser may download a processing engine from Voice2Sub’s CDN. Those engine requests do not contain your source file.

Need subtitles created automatically from audio or video?Voice2Sub can transcribe spoken audio when you need a complete subtitle workflow instead of a file utility.
