Straight answers
Are my subtitle files uploaded anywhere?
No. All parsing, fixing, and converting happens in your browser with JavaScript. Nothing is sent to a server — you can even disconnect from the internet after the page loads.
Is there a watermark or file-size limit?
No watermark on any output, no account, and no artificial file-size cap — a two-hour movie subtitle file is a few hundred kilobytes and fixes in milliseconds.
Which formats are supported?
In: SubRip (.srt), WebVTT (.vtt), and YouTube (.sbv). Out: SRT, VTT, or a plain-text transcript. Broken files — missing cue numbers, CRLF line endings, inverted timings — are repaired automatically.
How much does it cost?
It is free, with no account and no watermark. Single files and batch ZIP downloads both work with nothing asked of you.
