Pdf24.org reviews

The title says it all really.
Used PDF Creator for years, initially as a PDF Printer option
- still useful to produce "best quality" PDF files from anything & with higher quality than the default quality that MS Office PDF export or Libre Office PDF Export produces.
.
More recently used other things like online PDF24 Free Tools and PDF24 Free FAX FREE .
.. it all works WITHOUT difficulties and WITHOUT any advert junk everywhere
.
PDF24 is made by Geek Software GmbH from Berlin, Germany it says,
therefore privacy rules among the highest in the world.
.
User interfaces perhaps need update to be ready for the 2020's - might possibly be less easy to use on a pad / tablet / smartphone etc. It all works really well on desktop PC & Laptop
... see separate review of fax. PDF24. org & tools .pdf24. org
.
For Annotations/mark-ups like adding comments, the PDF24 Creator PC software is not doing in current version (Jan.2019), "but due to be added" - but markups can be done apparently using their online: tools . pdf24. org.
.
(markups/annotation of PDFs is one thing I use something else for on PC/Laptop (PDF-XChangeViewer free version)

Update added: I contacted them about something via their contact link under legal notice/contact - & was pleased/pleasantly surprised when I got eMail answer from a real person within just 15 minutes. In the modern world of auto-answers (or often no answers/no support) this is another plus for pdf24.
