Subtitle converter

Convert SRT and WebVTT, shift or scale their timing, and check overlapping cues before export.

Get started

Paste subtitle text or import an SRT or VTT file. Choose an output format.
A positive offset delays cues. For scaling, measure from the anchor, multiply by the time scale, then add the offset. Check clipping and overlaps before downloading.
