Formula or method
Convert timestamp separators and format headers while preserving cue textAssumptions
- Basic cue text is preserved. Malformed cues are omitted with visible diagnostics.
- WebVTT output retains parsed cue settings and NOTE, STYLE, and REGION blocks; SRT output cannot preserve those features.
- Preview and review the result in your subtitle editor before publishing.

Try it: convert an SRT file to WebVTT
This three-cue example keeps the caption text and timing while writing a WEBVTT header and period-separated milliseconds. Compare the first cue below.
- Download camera-tips.srt and load it in the converter.
- Choose WebVTT (.vtt), then select Convert subtitles.
- Confirm there are three cues, download the VTT, and test it in the player that will show the finished video.

If your result looks different
The VTT works locally but does not load on my website
Check the track URL, language and kind attributes, server Content-Type, and cross-origin policy in the player integration. Successful file conversion cannot correct how the destination serves or embeds it.
Positioning disappears when converting back to SRT
SRT cannot represent WebVTT’s STYLE and REGION blocks or cue positioning settings. Keep the VTT source and review formatting in the destination instead of expecting an identical round trip.
If the destination uses a different intro length, shift the cues against that final video master.
Adjust a consistent timing offsetHow to use the srt/vtt converter
Convert recognized subtitle cues between SubRip and WebVTT locally while preserving cue text and timing. The converter focuses on the common cue subset and does not promise lossless handling of every advanced style, region, positioning, or metadata feature.
Verify a representative cue after conversion
SRT normally uses comma-separated milliseconds and numbered blocks, while WebVTT begins with a WEBVTT header and uses periods in timestamps. The tool parses cues into one internal structure and writes the selected format, avoiding a fragile global punctuation replacement.
Check the first, middle, and last cues in the destination player. Pay particular attention to hourless WebVTT timestamps, overlapping cues, multiline captions, inline markup, cue settings, and notes that may not exist in both formats.
Protect advanced formatting and the original file
Basic cue text is preserved, but SRT and WebVTT have different capabilities. WebVTT regions, positioning, voice spans, style blocks, and metadata can require specialist conversion. Keep the original file whenever those features matter.
Files are processed in the browser and are not uploaded by the tool. Download the converted copy under a new name, validate it in the delivery environment, and retain the source until captions have passed final playback review.
Questions about this tool
Will converting SRT to VTT change the cue timing?
Recognized cue start and end times are preserved, with timestamp punctuation rewritten for the destination format. Validate the output when the source is malformed.
Are WebVTT styles and regions preserved?
Not necessarily. The tool handles common cues. Advanced WebVTT settings, regions, styles, and metadata may require a format-aware specialist workflow.
Does the converter upload subtitle files?
No. The current implementation reads, converts, and downloads subtitle text locally in the browser.
