What is ASS in subtitles?

ASS stands for Advanced SubStation Alpha. It supports richer subtitle styling than SRT, including positioned text, outlines, fonts, and more detailed formatting.

Does this SRT to ASS converter upload my file?

No. The conversion runs in your browser, so your subtitle text stays on your device during the conversion.

Will this keep my subtitle timing?

Yes. Standard SRT cue timing is preserved and converted into ASS dialogue timing in the output file.

What kind of ASS file does this tool create?

It creates a clean, basic ASS file with a default style so you can use it directly or refine it further in tools like Aegisub or other subtitle editors.
