How to Edit Subtitles Online
Four steps to fix subtitle text and timing — no software, no upload, no account.
- Load your subtitle filePaste your SRT or VTT content into the input area, or drag and drop the file directly. The editor auto-detects the format and loads every cue into an editable list.
- Edit text or individual timingsClick any cue to edit its text, start time, or end time directly. Add or delete cues as needed — useful for splitting a line that is on screen too long or merging two short cues.
- Shift all timings to fix syncIf the whole file is early or late, enter a global offset in seconds — positive to delay, negative to advance — and apply it to every cue at once instead of editing each one by hand.
- Export the edited fileDownload the result as SRT or WebVTT, or copy it to your clipboard. All edits happen in your browser — nothing is uploaded or stored on any server.
