Frequently Asked Questions
What is an SRT file?
SRT (SubRip Subtitle) is one of the most common subtitle file formats. It contains numbered subtitle entries, each with a start and end timecode and the text to display. Most video players and platforms support .srt files.
How do I sync subtitles that are out of time?
Use the "Shift All Timecodes" feature. If subtitles appear too early, enter a positive number of seconds. If they appear too late, enter a negative number. You can use decimal values like 1.5 for fine adjustments.
Can I create subtitles from scratch?
Yes. Click "Create New Subtitle File" to start with a blank editor. Add entries one by one using the "Add Entry" button, filling in timecodes and text for each line.
What timecode format does the editor use?
The standard SRT timecode format: HH:MM:SS,mmm (hours, minutes, seconds, milliseconds). For example, 00:01:23,456 means 1 minute, 23 seconds, and 456 milliseconds.
Is my subtitle file uploaded to a server?
No. All processing happens entirely in your browser using JavaScript. Your file never leaves your device, ensuring complete privacy.
Is this tool free to use?
