What kind of ads does this remove?

It detects common subtitle ad patterns including website URLs, subtitle site watermarks (OpenSubtitles, Subscene, YIFY, etc.), and credit lines like 'Subtitles by...'.

Does it work with both SRT and VTT?

Yes, the cleaner auto-detects the format from the file extension and preserves it in the output.

Will it break my subtitle timing?

No. Only the text content is modified — all timestamps remain untouched.
