when I merge two PDF files in PDF24 created in Adobe Acrobat (PDFs are 1.7 version), the resulting file is only version 1.3. I know I can merge files in Adobe Acrobat and get the right 1.7 version. But concerning cooperation with colleages, I need also 1.7 version from PDF24. We cannon hand out to customers 1.3 version of files, they are not acceptable. Thanks.
Oh, I see quite a lot of topics with only a question and without a single answer. So I guess there is no moderator who helps people systematically solve problems. Unfortunately. 🙁 Is there any other more reliable way to get an answer? Thanks.
