About this tool
Upload or paste an SRT or WebVTT subtitle file. The tool finds overlapping cues, backwards or zero-length timings, cues out of order, empty cues, lines that are too long and text that appears too fast to read. It can shift every timestamp earlier or later, fix overlaps, renumber cues and convert between SRT and VTT. It repairs timing and format only; it does not transcribe or translate. Your files are read in your browser and never uploaded.
Subtitle Repair and Converter (SRT and VTT) is part of ToolStack Hub's Text Tools. It runs entirely in your browser, which keeps your data private and makes results instant. There is nothing to install, no account to create and no usage limit.
Frequently asked questions
What is the difference between SRT and VTT?
SRT is the older, simpler format using commas in timestamps. WebVTT is used on the web, starts with a WEBVTT line and uses full stops in timestamps. This tool converts between them.
Can it sync subtitles that drift gradually?
It shifts every cue by a fixed amount. If the delay grows over time, you need a stretch or re-timing tool.
