FAQ

Questions about the Screenshot Annotator.

Can I move an annotation after adding it?

Yes. Switch to Select and drag an annotation to a new position.

Can I undo changes?

Yes. Undo removes the most recently added or moved annotation.

Does annotation remove metadata?

The exported file is rebuilt from pixels and does not copy the source metadata.

Is the screenshot uploaded?

No. Annotation and export happen locally.
