How to Convert Subtitle Files

Four steps to convert any subtitle or transcript format — no software, no upload, no account.

Step 1

Paste or drop your SRT file

Copy the content of your .srt file and paste it into the input area, or drag and drop the SRT file directly onto the input panel.

Step 2

Conversion happens automatically

The tool detects the SRT format, parses every cue, converts the timestamp separators from commas to periods, and adds the WEBVTT header required by the VTT spec.

Step 3

Optionally adjust timestamps

Use the offset field to shift all cues forward or backward by a fixed number of seconds — useful when your subtitles are slightly out of sync with the video.

Step 4

Download the VTT file

Click Download to save the converted .vtt file, or copy the output to your clipboard. The result is a valid WebVTT file accepted by all major video platforms and players.

SRT (SubRip Text) uses a comma as the millisecond separator in timestamps (e.g. 00:00:01,500) and has no header. VTT (WebVTT) uses a period (e.g. 00:00:01.500) and starts with a WEBVTT header line. VTT is the web standard and required for HTML5 video tracks and many streaming platforms. SRT is more widely supported by offline video players and editing software.
