              Migrated to HTTPS

              Happy to inform that Manytools is now fully Chrome-62-ready, thanks Google! A secure connection had been due for a very long time. Today we finally got around to upgrading the site to run on HTTPS. – (Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode.)
