The most common subtitle format, storing plain-text captions with simple timestamps for when each line should appear.
Safety guidance (not a guarantee)
Source code is plain text and doesn't execute on its own — it has to be compiled or run by a specific tool, which is where any real risk would occur.

Frequently asked questions
What is a .srt file?
The most common subtitle format, storing plain-text captions with simple timestamps for when each line should appear.
Can I edit a .srt file?
Yes — .srt files are commonly editable with software such as VLC.
Does having a .srt extension mean the file is safe?
