Caption Converter
Convert caption files between SRT, VTT, TTML, DFXP, SBV, SUB, ASS, SCC, LRC, and QuickTime Text. Extract readable transcripts with light, paragraph, or cue-by-cue cleanup.
The Caption Converter is a fast, no-nonsense utility for turning captions, subtitles, and transcript-style files into the formats your workflow actually needs. Convert between SRT, VTT, TTML, DFXP, SBV, SUB, QuickTime Text, ASS, SCC basic, and LRC — or strip timestamps to generate a clean, readable transcript.
Managing caption files across platforms can quickly become frustrating. Whether you're working with Zoom-generated VTT files, YouTube's SBV format, TTML/DFXP, SubViewer, QuickTime Text, or advanced subtitle formats like ASS, the converter helps move captions into the format required by your editing software, video platform, or publishing workflow.
Beyond format conversion, the tool can extract timestamp-free transcripts with multiple cleanup styles. Use paragraph cleanup for readable prose, light cleanup when you want to preserve more line breaks, or one-line-per-cue cleanup when reviewing caption timing and text side by side.
The converter supports common web, video, accessibility, and editing formats, including SRT, VTT, TTML, DFXP, SBV, SUB, QuickTime Text, ASS, SCC basic, and LRC. With just a few clicks, you can import, preview, repair, and export captions in the format your workflow requires.
Everything runs directly in the browser, which keeps the workflow fast and private. Your caption text does not need to be uploaded to a server just to convert formats, clean transcript spacing, or download a revised caption file.
