How to convert SRT to ASS

Convert SRT subtitles to ASS (Advanced SubStation Alpha) in seconds. CutConvert writes a v4.00+ script with a Default style and one Dialogue line per cue: italics, bold, underline and font colours become override tags, a cue the source placed at the top gets {\an8}, line breaks become \N and a speaker name fills the Name field.

  1. Add your SRT files

    Drag your .srt files onto the drop zone, up to 10 at once, or click to browse. WebVTT, SBV, SCC, STL and transcript files work on this page too.

  2. Convert SRT to ASS

    Press Convert. CutConvert writes one .ass per file, styled with override tags.

  3. Download your result

    Download the converted file instantly, or a single ZIP archive when you convert a batch of files.

SRT file and ASS subtitles, explained

ASS is the subtitle format of Aegisub, mpv, VLC and most burn-in tools. Unlike SRT it carries per-cue styling and placement, so it is the right target when italics, colours or a top placement have to survive. CutConvert keeps everything the SRT carried and writes a 1920 by 1080 script with a single Default style you can retune in Aegisub.

Turn SRT subtitles into styled ASS subtitles for Aegisub, mpv, VLC and burn-in workflows. It is free to start, encrypted in transit, and converts a whole batch into one ZIP — sign in when you need large, high-volume jobs.

SRT to ASS FAQ

Are SRT tags kept?

Yes. <i>, <b>, <u> and <font color> become {\i1}, {\b1}, {\u1} and {\c&HBBGGRR&} override tags, closed where the SRT closed them.

Where do speaker names go?

Into the Name field of each Dialogue line, which players and Aegisub show as the actor. They are not burnt into the text.

Can I convert ASS back to SRT?

Yes. Use the ASS to SRT converter at /ass/srt, which turns the override tags back into SRT tags.

Questions, answered

Where are my files processed?

In your browser. The converter runs on your own machine and the file never leaves it; the site only records that a conversion happened. CutConvert never sees, stores, sells or shares your media.

Is it free? Do I need an account?

Small, everyday batches are free to convert. For large or high-volume jobs you'll create an account and upgrade, which keeps the free tier fast for everyone.

What do I get when I convert multiple files?

Drop several files and you get back one ZIP archive containing every converted file. Convert a single file and you get that one file back, no ZIP.

Which formats are supported?

Timelines: Premiere .prproj, DaVinci Resolve .drp (as exported, or gzip- or Zstandard-wrapped), Avid AAF and Final Cut FCPXML in; FCP7 XML, FCPXML, Resolve .drp, CMX 3600 EDL and shot-list CSV out. A Premiere or Final Cut edit travels with its transitions, markers, titles, opacity and scale keyframes, clip volume, speed changes, nested sequences, bins, audio channel routing and each file's own frame rate, wherever the output has a place for them; an Avid AAF brings its transitions, markers, clip levels with their keyframes, muted tracks, nested stacks and each clip's own rate. Captions and transcripts, read and written: SRT, WebVTT, SBV, ASS, TTML, DFXP, iTT, SCC, MCC (a second 608 channel comes out as its own file), EBU-STL, Avid caption TXT, CapCut drafts of any size, timed CSV, Word, plain text, Whisper, WhisperX, AssemblyAI, Deepgram, Rev.ai and CapCut JSON, Premiere transcript JSON and .prtranscript, Rev, Otter and Word-style transcripts, with italics, colour, placement and speakers kept where the output can hold them and measured word timing into Premiere. EDLs become event CSV reports. The capability table lists what every pair keeps.

Can I pick a frame rate?

Yes. For EDL and Avid caption output you can choose 23.976, 24, 25, 29.97, or 30 fps, or let CutConvert auto-detect it from your source.
