Convert SSA to SRT

ASS is the later revision, with more styling features and a slightly different field order in the Events section. For the purposes of getting to SRT the difference does not matter: this page and the ASS page run the same parser, which finds the columns by name.

No. SSA writes times in hundredths of a second and SRT in thousandths, so each stamp is widened rather than rounded — 0:00:02.25 becomes 00:00:02,250. Nothing is recalculated, so a file that was in sync stays in sync.

No. There is no download, no account and no upload: pick the file and the SRT is ready immediately, because the whole conversion runs as JavaScript in the page you are already on.

They are dropped, on purpose. SSA can store fonts, colours, positions and karaoke effects that SubRip has no way to express and that a plain SRT player would ignore anyway; the converter keeps every cue text and timing and leaves the styling behind. What you get is the readable subtitles a modern player actually uses, without the markup that was making the file refuse to load.

SSA (SubStation Alpha) predates today players, and many of them only reliably read SubRip. The cues inside are usually fine; it is the older format and its styling block that trip up a modern app. Converting to SRT keeps the same lines and timings in the format current players expect, which is why an archived subtitle that would not open suddenly works.
