SRT Shift Time

Your subtitles drift a couple of seconds from the audio. The SRT Shift Time tool moves the entire track by one offset.

Enter a signed timecode — +HH:MM:SS,mmm to delay, -HH:MM:SS,mmm to advance — and every cue start and end shifts by that amount. The numbering and wording stay the same; only the timing moves. Negative results are clamped to zero so the file remains valid. Paste your SRT, set the offset, and resync.

• Whole-track shift: one offset for all cues.
• Signed input: delay or advance.
• Safe clamp: no negative timecodes.
• Lossless text: wording preserved.
• Quick fix: one click to resync.
• Private: runs in your browser.

1. Paste your SRT (sample preloaded).
2. Enter an offset like +00:00:02,000.
3. Click Shift Time and copy or download.

Example 1 — Late captions. Shift +2s to catch up to audio.

Example 2 — Early captions. Shift -1.5s to match speech.

Example 3 — Intro trim. Move everything after a recut.

• Instant resync: fixes drift fast.
• Predictable: uniform offset.
• Safe: clamped to zero.
• Lossless: text preserved.
• Private: nothing uploaded.
