Frequently asked questions

What is a .sketch file?

Native project format for the Sketch UI/UX design app, storing artboards, layers, and symbols.

Can I edit a .sketch file?

Yes — .sketch files are commonly editable with software such as Sketch.

Does having a .sketch extension mean the file is safe?

No single extension can guarantee that. Plain documents are generally low-risk to view. If the format supports macros or embedded scripts, keep them disabled unless you specifically expect and trust them. Always consider where the file came from, not just its name.
