SubRip Subtitle format — a plain text file listing subtitle sequences with start/end timecodes. It is the most widely supported subtitle format.

Can I import existing subtitles?

Yes. Paste SRT text into the editor and the parser will populate the timeline, letting you edit and re-export.

What is the timecode format?

HH:MM:SS,mmm — hours, minutes, seconds, milliseconds. For example: 00:01:23,456 means 1 minute 23.456 seconds.

Use our Subtitle Generator tool instead — it auto-generates SRT from any video with AI transcription.

Not natively. Standard SRT is single-language per file. Use separate SRT files for each language and load them alongside in the player.

Yes — UTF-8 encoding is used to preserve accents, CJK characters, and emoji.
