FAQ
What is the difference between the two options?
"Characters only" turns Traditional characters into Simplified ones, so 軟體 becomes 软体. "Taiwan vocabulary → mainland" also converts wording, so 軟體 becomes 软件 and 影片 becomes 视频.
Are my files uploaded?
No. Conversion happens entirely in your browser.
Will ASS fonts and effects break?
No. Only the dialogue text is converted; styles, font names and override tags stay the same.
Can it read old Big5 subtitles?
Yes. Big5, GBK and UTF-8 are detected automatically, and the output is UTF-8.
