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?

No single extension can guarantee that. 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. Always consider where the file came from, not just its name.
