Frequently Asked Questions

What is an SRT file?

SRT (SubRip Subtitle) is the most common subtitle file format. It contains numbered subtitle entries with timestamps and text. Most video platforms including YouTube, Vimeo, Facebook, and media players like VLC support SRT files natively.

How do I add subtitles to my YouTube video?

Go to YouTube Studio, select your video, click "Subtitles" in the left menu, click "Add Language", then "Upload file" and choose "With timing". Upload the .srt file generated by this tool. YouTube will sync the subtitles with your video.

What's the ideal subtitle duration?

Most subtitle guidelines recommend 1-7 seconds per subtitle, with 2-3 seconds being ideal for short sentences. The default 3-second duration works well for most content. Adjust based on your speaking speed and content complexity.

How many characters per line should subtitles have?

The standard is 42 characters per line for YouTube and most broadcast platforms. Netflix recommends 42 characters, while BBC recommends 37. This tool defaults to 42 but lets you customize between 20-80 characters.

Can I edit individual subtitles after generating?

Yes. Click on any subtitle in the preview panel to edit its text, start time, or end time. You can also delete individual subtitles. All changes are reflected in the downloaded SRT file.

Is this tool free?

Yes, completely free. No signup, no watermarks, no limitations. Everything runs in your browser so your script text never leaves your device.
