Questions

Why are signs and karaoke lines doubled or out of place?

ASS files often layer several lines at once for signs and effects. SRT cannot position text, so those lines show at the bottom. Turn on "Clean up" to remove empty or effect-only lines.

Is my subtitle file uploaded anywhere?

No. Your browser reads and fixes the file on your own computer. Nothing is sent to a server, so private files are fine, and the tool keeps working offline once the page has loaded.
