Privacy details

Subtitle converter processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Using the subtitle converter

The converter parses every cue, checks start and end times, then writes the destination format. Text and line breaks are preserved. An optional offset moves all cues together; cues cannot be shifted before zero.

A worked example

An SRT cue from 00:00:01,000 to 00:00:03,000 becomes a WebVTT cue from 00:00:01.000 to 00:00:03.000.

Before you use the result

Plain cues only. Styling blocks, regions, positioning settings and embedded markup are rejected instead of silently discarded. This does not burn captions into a video.
