Does pdf cover image generator upload my files?

PDFs that require a password are not supported in this version. Remove protection with the correct password before using the tool.

Newly generated files preserve the visible content handled by this tool, but advanced forms, bookmarks, annotations, layers, or scripts may not carry over.
