Frequently asked questions

What is an overlapping subtitle?

A subtitle that starts before the previous one has finished. Overlaps can make players hide or flash lines, so they are worth fixing.

Does it change my file automatically?

No — it finds the overlaps and shows the timing repairs for you to review in SRT or VTT files before you save.

Does it work on both SRT and VTT?

Yes — both formats are supported, and the tool is free with no signup needed.
