Choosing a subtitle format
Subtitle files are timed text: each cue has a start, an end and the words to show. SRT is the plain format nearly every player and video site accepts, WebVTT is the one browsers use, ASS adds fonts, colours and positioning, SBV is YouTube's, and TTML is what broadcasters and streaming services deliver. Converting between them keeps the words and the timing; styling survives only where the target format can express it. Because a subtitle file is text, a wrong character set is the most common thing that goes wrong.
Questions
Which subtitle format should I use?
SRT if you do not know: practically every player, editor and video site accepts it. WebVTT for video on your own web page, ASS when you need fonts, colours and exact positions, SBV for YouTube Studio, and TTML only if a broadcaster or streaming service asks for it.
Why do accented letters show up wrong in my subtitles?
Old subtitle files often use a legacy character set, not UTF-8. A file that says which charset it uses is read correctly; one that does not is read as Windows-1252, which is right for Western European languages and wrong for others. Saving the original as UTF-8 in a text editor first fixes it.
Which subtitle formats can toany convert?
SRT, VTT, ASS, SBV, SMI and TTML. Each format page lists exactly what it can be converted to and from.

Do I have to pick the input format?
No. toany reads the file's contents to work out what it is, even when the extension is wrong, and then offers the formats it can become.

Yes. Add as many as you like, mix types if you want, and download the results one by one or together as a ZIP.
