Free Online STL to TXT Converter
Our STL to TXT converter reads Spruce Subtitle input and produces Plain Text output entirely in your browser. All timing and styling are stripped so you are left with a clean transcript of the spoken text. The conversion runs client-side, so your subtitle files are never uploaded to a server.
Input Format
STLSTL (Spruce Subtitle) is a text-based subtitle format used in DVD authoring and some broadcast workflows. Each entry uses comma-separated start and end timecodes followed by the subtitle text, with the pipe character (|) denoting line breaks. This text STL variant is distinct from the binary EBU STL broadcast format.
Output Format
TXTTXT (Plain Text) output strips away all timing, sequence numbers, and formatting, leaving only the spoken dialogue as a clean transcript. This is useful for extracting scripts, building searchable transcripts, feeding text into translation or AI tools, or repurposing subtitle content as plain documents.
