SRT to ASS — subtitles you can style
Convert .srt subtitles to .ass for Aegisub, mpv and VLC: italics, colours and top-of-screen lines carried over into a clean default style.
About this conversion
ASS is where subtitles go to be styled — fonts, outlines, positions — in Aegisub or straight in mpv and VLC. The conversion gives a clean starting point: a 1080p script with one readable default style, white text with a dark outline, and every line from the SRT with its italics, colours and top-of-screen placement turned into ASS tags. Two-language files merged here become two styles, one at the bottom and one at the top.
Just want to look inside it?
The same tool without converting anything: open the file and read it.
Fix it before you save it
The file stays open after it is read, so the format is picked at the end: the same subtitles can leave here as VTT, SBV, SUB (MicroDVD), TTML / DFXP, SAMI (.smi), LRC, TXT, Word, Excel or PDF. Before that you can move every line earlier or later, stretch the timing to a different release of the film, remove [DOOR SLAMS] and speaker names, put a second language under the first, and see which lines break the rules studios follow — too long, too fast, overlapping.
Questions
- Which resolution is the script?
- 1920×1080. ASS scales to any video, so it looks the same on a 720p file.
- Can I change the font here?
- Not yet — open the file in Aegisub for that. Timing, text and encoding fixes can all be done here first.
