Subtitle Sync, Shift & Clean Tool

Click or drag files here...

Accepts: SRT, ASS, VTT, SBV

(File size: 10 B ~ 5 MB)

Simple mode simply shifts all subtitle cues by the specified value (in milliseconds) below. Enter a positive number to add delay to the cues, or add a negative one to make them appear sooner.

If the subtitle cues are shown at the right time in the beginning but later become increasingly out of sync, you can try using the Linear Shift mode to fix them. The most likely cause of this is the subtitle file is intended for a video with a different frame rate or from a different source.

In this section you can clean up the cues of the subtitle files you have uploaded. Click the Apply button to apply the changes to all selected subtitle files below. Currently only SRT and VTT files are supported.

You don't need to re-upload the files if you intend to apply this to the same files already listed below. You can simply select the files and click Apply. All changes will be immediately applied in the browser before you download the files.
