Can I adjust the timing of all lines at once, like shifting the whole file by two seconds?

Yes, a bulk time-shift adjusts every subtitle line's timing together, useful when the whole file is consistently out of sync.

Does it validate the .srt format so I don't accidentally break it?

Yes, edits are applied through the proper .srt structure, avoiding the syntax errors that come from editing timestamps by hand in a plain text editor.

Can I split or merge subtitle lines?

Yes, you can adjust individual lines' text and timing, including splitting a line into two or combining lines together.

Does SRT Editor upload my files to a server?

No. SRT Editor runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Subtitle timing is rarely perfect on the first pass — a line lags slightly behind the speech, or a typo needs fixing — and .srt is a plain text format with a specific timestamp syntax that's fiddly to edit correctly by hand in a text editor. This tool lets you edit subtitle timestamps and text in an .srt file directly, with the format handled correctly behind the scenes so a manual syntax mistake doesn't break the file.
