Standalone PDF viewers such as SumatraPDF, MuPDF, Okular or PDFX-Change Editor allow to display PDF metadata and properties such as used fonts, size, date of creation, author etc., typically with a Ctrl + D hotkey.
However, I cannot figure out how to obtain the same info from the embedded PDF viewer in any of the Chromium-based web browsers. So far I tried Google Chrome, Opera, Vivaldi and none of them seem to provide this feature out of the box.
Pressing Ctrl + D obviously doesn't work in browsers (adds page to bookmarks), and there is no UI elements to click on in order to retrieve the PDF metadata.
Is it possible to view properties of a PDF document without saving and reopening it in a standalone viewer?
