Correct subtitles that appear a few seconds after the dialogue
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.Subtitles that trail the speech by a fixed gap come from a file cut for a different release of the same video. Play a line, note how late it is, and subtract that many seconds here; the fix applies to the whole file at once and can be undone by shifting back.
Play the video and note how many seconds the subtitles appear after, or before, the speech.
Press Choose a subtitle file and pick the .srt or .vtt file that is out of step.
Type that gap in Shift the timing, as a minus number if the subtitles come late, so every cue moves together.
Under Save as pick SRT or VTT, then press Download to save the corrected subtitles.
Subtitle Converter reads an SRT or WebVTT file, shows you what is in it, and writes it back in either format. It also moves the timing of every cue by an amount you type, which is the fix for subtitles that run early or late against the video.
The two formats are nearly the same file. Both are a list of cues, each with a start time, an end time and one or two lines of text. SRT separates the seconds from the milliseconds with a comma and numbers its cues; WebVTT uses a dot, begins with a WEBVTT line, and may name a cue or give it positioning such as line:90% align:center. Those small differences are enough to stop a player loading the wrong one, which is why converting is usually all that is needed. A browser playing video with a track tag requires WebVTT; VLC, Premiere and most television players expect SRT.
Timing is the other half. A subtitle file cut for a different release of the same film is often correct in pace but wrong by a fixed number of seconds. Play one line, see how late or early it is, and shift the whole file by that much. Every cue keeps its own length, so the rhythm of the dialogue is unchanged, and nothing is pushed before the start of the video.
The rest of the article, and all 6 questions about Subtitle Converter, are on the Subtitle Converter page.
Drop the SRT on this page and choose VTT. The cue list is read, the WEBVTT header is added, and the comma before the milliseconds becomes a dot, which is the difference browsers care about. Download the result and point your video's track tag at it. Nothing is uploaded.
Play a line and note how many seconds late or early it appears. Type that number here, with a minus sign to pull the subtitles earlier, and every cue moves by the same amount while keeping its own length. Shift back by the same number to undo it.
No. The file is read, converted and saved entirely in your browser on your own device, so an unreleased script or an unpublished episode never leaves your computer. There is no account, no upload and nothing on our side to delete afterwards.
Subtitle ka time theek karna ho to pehle dekhiye ki subtitle kitne second aage ya peeche chal raha hai. Wahi number yahan daaliye, minus ke saath agar subtitle late hai. Har cue utna hi khisak jaata hai aur uski lambai wahi rehti hai, so the dialogue keeps its rhythm.
