SRT is plain on purpose. ASS is the format to move to when you want subtitles at the top of the screen, a colour for each speaker, or a font of your own. Converting gives you an ASS file with a default style and your text and timings intact, ready to style here or in Aegisub.
What changes when you convert SRT to ASS
Not everything survives the trip. Converting SRT to ASS drops or flattens the following:
Questions
How do I convert SRT to ASS?
Drop the .srt above and download the .ass. Text and timings carry across unchanged.
Why convert SRT to ASS?
To control how the subtitles look. Once the file is ASS you can change the colour or move the subtitles on screen, and the change stays in the file.
Will my player show ASS subtitles?
VLC, mpv and most desktop players will. Some TV apps and Plex clients can't draw ASS styling, so keep the SRT if that's where you watch.
Can I convert it back to SRT later?
Yes, with ASS to SRT, though styling you add is dropped on the way back.
