I uploaded a PDF, but it is not displayed correctly.

Please pay attention to create your PDFs with the compatibility “Acrobat 5” (PDF 1.4).

Background: There are a few compression methods in the newer PDF versions, starting from Acrobat 6 (PDF 1.5), which are not supported by the PDF library Converia uses. That does not mean newer PDFs do not work in Converia at all, there is just no guarantee.

Adobe’s general recommendation for widely used PDFs is to create them with the compatibility “Acrobat 5” (PDF 1.4). This way a correct display can be ensured on all systems.
