Subtitle Tools

Subtitle work often needs small format fixes: convert SRT to VTT, convert platform exports back to SRT, extract clean transcript text, or shift all timestamps after an edit. These tools cover the common lightweight caption workflow.

Which tool should you choose?

Tool Best for When to use it
SRT to VTT HTML5 video captions Use when publishing subtitles on web pages
VTT to SRT Editing workflow Use when an editor or platform expects SRT
SRT to Text Transcript extraction Use when timestamps are no longer needed
Subtitle Time Shifter Timing repair Use after audio or video offset changes

Convert between subtitle formats

Use SRT to VTT for web video, VTT to SRT for editors, ASS/SSA to SRT for styled subtitle exports, and SBV to SRT for simple caption workflows.

Clean and repurpose subtitles

SRT to Text removes indexes and timestamps so subtitles can become a transcript, summary source, or article draft.

Fix timing after edits

Subtitle Time Shifter moves all timestamps forward or backward by milliseconds when audio or video has changed.

Common mistakes

  • Forgetting to preview subtitles after format conversion.
  • Expecting ASS style effects to survive a lightweight SRT conversion.
  • Using seconds instead of milliseconds when shifting timestamps.

FAQ

Which subtitle format is best for web video?

WebVTT is commonly used for HTML5 video captions, while SRT remains common in editors and subtitle sharing.

Will ASS styles be preserved?

No. The lightweight ASS/SSA converter extracts timing and dialogue text, not advanced styling.

Can I fix subtitles that are all late by two seconds?

Yes. Use the time shifter with a positive or negative millisecond offset.
