With Chromium-type ANDROID browsers we can download pages to view later offline with the browser.
They are saved as mhtml (NOT html).
My phone has system app “HTML Viewer Version 8.1.0”, but it won’t read these files.
In Google PlayStore there are some apps to do this…
I’ve tried this one and it works OK, it can view the mhtml files and can also Save as PDF.
Is there a similar app in F-Droid repository?
