How to Edit Subtitles Online

Four steps to fix subtitle text and timing — no software, no upload, no account.

Step 1

Load your subtitle file

Paste 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.

Step 2

Edit text or individual timings

Click 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.

Step 3

Shift all timings to fix sync

If 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.

Step 4

Export the edited file

Download 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.

If every subtitle in the file is early or late by the same amount, enter a global offset in seconds in the "Shift all timings" field — a positive number delays every cue, a negative number advances them — and apply it.
