Free SRT Subtitle Formatter

How to build an SRT file

An SRT file is a plain-text subtitle file. Each entry has a number, a start and end time, and the subtitle text. Many editors and players need exactly this layout, and small mistakes stop a file from loading.

The SRT Formatter checks your timed text, rebuilds the numbering, puts the timecodes in the correct format, and tells you about any cue that ends before it starts. It runs in your browser, and nothing you paste is sent to a server.

1. Paste your timed text. Each subtitle needs a timing line such as 00:00:01,000 --> 00:00:04,000, followed by the text.
2. Check the result. If a cue has an error, the tool tells you which one.
3. Download the .srt file, or copy the text.

What text the formatter accepts

Blocks separated by a blank line, with the timing on one line and the subtitle text on the lines below. Sequence numbers are optional. Timing can use a comma or a dot before the milliseconds, and hours can be left out for short clips.

The formatter does not create timings for you. It checks and tidies the timings you already have.

Using your .srt file

Most editors import an .srt directly. In Premiere Pro, use File, then Import, and select the file. In DaVinci Resolve, right-click in the Media Pool and choose Import Subtitle. In VLC, put the .srt in the same folder as the video with the same file name.
