SRT subtitle editor

Open an existing SRT or VTT file, fix the wording and the timings, and export it again — all on your own device.

Editing subtitles without uploading them

Subtitle files are often the last thing standing between a finished video and publishing it — a mistimed line, a misheard name, a caption that flashes past too quickly to read. Most online SRT editors ask you to upload the file first, which is an odd thing to require for what is essentially a text document, especially when the subtitles belong to unreleased footage.

This editor reads the file in your browser. Each cue appears with its start time, end time and text, all editable. Timestamps are validated as you type, so a malformed time is flagged immediately rather than producing a file players silently reject.

The timing tools

Shift all moves every cue by the same number of seconds — the fix when subtitles are consistently early or late. Tidy timings enforces a minimum duration so no caption flashes past unreadably, adds a small gap between consecutive cues, removes overlaps, and re-wraps text to a maximum line length (42 characters is the usual broadcast convention). Split cuts a long cue in two at your cursor and divides its time proportionally; merge joins a cue to the one after it.
