Sync subtitles to two points
Enter when one early line and one late line are actually spoken. The tool stretches and moves every other line to match, which fixes an offset and a drift together.
Positive shows subtitles later, negative sooner. Seconds, or a time like 00:01:05,300.
Find each line in your video and type when it is actually spoken.
Pick the output format below. Timing and text are kept.
| # | Before | After | Text |

How it works
- Drop in your subtitle file.
- Pick a line near the start and type when it is actually spoken in the video. Do the same for a line near the end.
- Download the file with every line retimed.
Questions
Which lines should I pick?
The further apart the better: one in the first few minutes and one in the last few. Choose short lines that start right when someone speaks.
Is my subtitle file uploaded anywhere?
No. Your browser reads and fixes the file on your own computer. Nothing is sent to a server, so private files are fine, and the tool keeps working offline once the page has loaded.
