Subtitle Tool
Parse, convert, repair, and validate subtitle files.
Drop in an SRT, VTT, SBV, or ASS file and convert to any format. Apply bulk operations, validate against broadcast guidelines, and download the result.
Input
Paste subtitle text or drag and drop a file.
Why This Tool Exists
Most subtitle tools stop at conversion. Delivery problems start after that.
The real work is catching overlaps, broken tags, reading-speed violations, missing gaps, framerate mismatches, and delivery-specific export quirks before the file gets handed off.
Broadcast Subtitle Formats
What SCC, EBU-STL, and Graphics STL actually carry, and why those exports need frame-accurate timing.
