SRT (SubRip Subtitle) is a popular subtitle file format that contains numbered subtitles with start/end timecodes and subtitle text. It's widely supported by video players and editing software.

The validator checks for timing errors (end before start), improper timecode formatting, duplicate or missing subtitle numbers, overlapping time intervals, empty subtitle lines, and formatting issues like missing line breaks.

Can I validate large SRT files?

Yes, the tool can handle SRT files of various sizes. All processing happens client-side in your browser, so there are no file size limits imposed by server upload restrictions.
