Convert SRT to ASS subtitles
Convert your subtitles in seconds — entirely on your machine. Nothing is uploaded: the file never leaves your device. CueForge preserves styling and positioning wherever ASS can express it, and shows you the exact loss matrix below before you commit.
What gets kept, what gets dropped
| Feature | SRT → ASS |
|---|---|
| Italics | Kept |
| Bold | Kept |
| Underline | Kept |
| Font colour | Kept |
ASS can additionally express Positioning and Styling override tags, which you can add in the studio after converting.
About SRT
SubRip (.srt) is the most widely supported subtitle format: numbered cues with start and end timecodes plus plain text, and basic inline tags for italics, bold, underline and font colour. It carries no positioning or advanced styling, which makes it the universal lowest-common-denominator that almost every editor and player accepts.
About ASS
Advanced SubStation Alpha (.ass, evolved from SubStation Alpha .ssa) is the styling-rich format favoured by fansubbing and anime. It defines named styles plus inline override tags for fonts, colours, bold/italic/underline and precise on-screen positioning, making it far more expressive than SRT.
