Drop SRT (SubRip) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the ASS, or download everything as one ZIP if you converted several files.
The SRT to ASS converter is part of this page and runs inside your browser. Your subtitles are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
SRT can only say what to show and when. ASS lets a subtitle editor such as Aegisub give each line its own font, colour, outline, position and animation, which is why fan-subbers and karaoke makers work in it. Converting an SRT to ASS is the usual first step before restyling a plain subtitle track.
The text is read as UTF-8 or UTF-16, whichever the file is. An older file in another code page is read using the charset it declares, or as Windows-1252 if it declares none, so accented letters in an unlabelled legacy file can come out wrong. A file that is not text, such as the picture-based subtitles of a DVD, is refused instead of being converted to nonsense. Of the styling, only italic, bold, underline and the position on screen (top, middle or bottom, left, centre or right) travel between formats; fonts, colours, outlines and effects do not. The file is written with a single Default style (Arial, white with a black outline) that the player or Aegisub can restyle, and times are rounded to hundredths of a second, the precision ASS has.
SRT is the plain subtitle format nearly every player accepts: a number, a time range such as 00:01:02,500 --> 00:01:04,000 and one or two lines of text. It has no official specification and only basic styling, which is why it travels so well.

SRT converterASS adds styles to subtitles: fonts, colours, outlines, shadows, exact screen positions and animation effects. Fan-subbed anime and karaoke use it heavily. SSA is the earlier version, and the .ssa extension is read as the same format.

No. The SRT to ASS conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
No further quality is lost: ASS stores the decoded audio exactly. The result is identical in content.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the SRT file, press Convert and save the ASS. There is nothing to install.
Yes, but a subtitle file is small. Files up to 50 MB are accepted, far more than any real subtitle file. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
