The editor reads the cue numbers, timestamps and text on this device. Files are not uploaded.

An SRT editor lets you change subtitle text, cue order, and start or end times in a SubRip file. This online editor also finds timing problems, shifts every cue together, previews captions on a timeline, and exports a clean, renumbered SRT without uploading the file.
Drop an .srt file, choose it from your device, paste the raw text, or load the example.
Change text or timestamps, reorder or insert cues, and use the timeline preview to inspect when each subtitle appears.
Find and replace recurring text, sort cues by time, or shift the complete track earlier or later by a precise number of seconds.
Resolve blocking time errors, then copy or download a UTF-8 SRT with sequential cue numbers and standard comma timestamps.
SRT is a plain-text sidecar format: each cue contains a number, a start and end timestamp, subtitle text, and a blank separator. This editor accepts comma or dot milliseconds, keeps optional position settings, and normalizes line endings and numbering when you export.
Your subtitle text stays on this device. The page does not need an account, does not send the file to a processing server, and can handle dense subtitle tracks with up to 10,000 cues through a paged editor.
No. Reading, parsing, editing, previewing, and exporting happen in your browser. The subtitle file and its text are not sent to a processing server. Your edits remain in the current page until you download the result or close the editor.
Yes. You can open, edit, validate, copy, and download SRT files without an account, watermark, or payment. The editor runs with browser JavaScript and does not depend on paid transcription or translation services.
The editor accepts files up to 5 MB and tracks with up to 10,000 readable cues. It shows 10, 25, or 50 cues at a time so long subtitle files stay responsive. Very large projects are easier to review when split by episode or video.
Yes. Enter a positive number of seconds to move all cues later or a negative number to move them earlier. The editor applies the same millisecond offset to every start and end time, preserving cue duration and spacing while preventing negative timestamps.
It flags invalid timestamp fields, cues whose end is not later than the start, overlaps with the next cue, cues that appear out of chronological order, and empty subtitle text. Import notes also identify missing, duplicate, or non-sequential cue numbers.
The editor keeps cue text and optional timestamp-line settings. Export removes extra blank lines inside a cue, writes standard comma milliseconds, normalizes line endings, and numbers all cues from 1 in their current editor order. Blocks that could not be parsed are not included.
Yes. SRT cue text can contain Unicode characters, so the editor works with multilingual subtitles, right-to-left scripts, emoji, and accented text. Downloads use UTF-8. Your video player or editing app still needs a font that supports the characters.
