A little subtitle fine-tuning

SRT Subtitle Editor

Edit an existing subtitle file, check its structure, and fix a constant timing offset. Everything stays in this browser tab.

Open SRT

Subtitle source · UTF-8 · up to 2 MB / 3,000 cues

Shift all cues by (seconds)

Paste or open an SRT file to begin.

No transcription or video preview. Existing subtitle text is edited locally; it is never rendered as HTML.

Fix a constant timing offset.

If every subtitle appears two seconds too early, apply +2. If every subtitle appears two seconds too late, apply -2. Shifts that would create negative times are rejected.

If the delay grows over time, a constant offset will not fix it. Check the video version and frame-rate conversion in a video-aware subtitle editor. Read the timing guide →

Edit, validate, export.

Change text and timestamps directly in the source box. Keep a blank line between cues and use the format 00:00:01,000 --> 00:00:03,000. Downloading normalizes line endings and renumbers cues in their current order; cues are not automatically sorted.

For an Android recording-to-text workflow, explore Scribe. This browser editor does not generate subtitles from audio.
