Powerful Subtitle Utilities in One Place
Each tool is fast, lightweight, and built for professionals who need reliability.
Subtitle Time Shifter
Easily adjust subtitle timing — shift timestamps forward or backward to fix synchronization issues caused by frame-rate differences.
With these Subtitle Edit Tools, timing adjustments can be made effortlessly.
Subtitle Merger
Combine multiple subtitle files into a single timeline. Ideal for merging translated scripts or episodic content.
Subtitle Splitter
Split large .srt or .vtt files into smaller chunks by line count or duration — perfect for breaking long movies into manageable parts.
Subtitle Overlap Fixer
The Subtitle Edit Tools help detect issues that commonly arise in subtitle files.
Detect and fix overlapping cues automatically for smoother playback and better readability.
All of these tools support both .srt and .vtt formats, giving you complete flexibility.
How Subtitles Edit Works
Subtitles Edit uses advanced JavaScript parsing and timestamp conversion logic to process your subtitle files directly in the browser.
There are no backend servers — your data never leaves your computer.
When you convert SRT to VTT or convert SRT to WebVTT, the system:
Reads your file with the FileReader API
Parses timestamps (
00:01:02,000→00:01:02.000)Preserves cue numbering and line spacing
Outputs a perfectly formatted
.vttfile ready for use
Similarly, when converting VTT to SRT, it reverses the process — switching dots to commas and cleaning up the headers automatically.
This is why both SRT to VTT conversion and VTT to SRT conversion happen instantly and privately.
Supported Formats
We support a wide range of formats with our Subtitle Edit Tools.
| Format | Example Timestamp | Common Use |
|---|---|---|
| SRT (SubRip) | 00:01:05,230 --> 00:01:09,450 | Used by editors & translators |
| VTT (WebVTT) | WEBVTT header + 00:01:05.230 --> 00:01:09.450 | Used by browsers & streaming platforms |
Subtitles Edit handles both formats seamlessly, making it the best place to convert SRT to WebVTT and convert VTT to SRT offline.
