Here at Zyro you don't need an FTP client, File Manager nor cPanel, as everything is managed within your website editor and settings.
You can add various pages, sections, and elements to it easily!
Additionally, you can upload any file to a cloud (e.g. Google Drive), and paste the link to the file anywhere on your site (you can insert a link into a text, button, or image).
You can also use the Embed Code element to add custom widgets to your website, including PDF viewers.
