It’s getting harder and harder to find a free pdf viewer plugin with simple download capabilities, but this one has it. Easy to use and effective. One thing I would like to see added is the ability to specify the alignment of the pdf viewer in the post.

Great little plugin. It display the PDF greatly with the block editor and has lots of useful features.

Free version you can set height and width from the block controls, and that’s it! Can’t even tell it to use 100% width, have to specify in pixels. Understand it has lots of controls for the user, but I need controls on how it displays, like initial zoom settings and definitely 100% width settings. Disappointed.
