Oh, my! Tastyapps released a new version after several years of silence, keeping their paid users with a nonfunctional app for so long. On top of this there is no upgrade path for v1.x users, registered before 2017.
Looking at their site we read that the "new" version has added new problems to the existing ones, namely:
If you are capturing a page with PDF output format, Vector conversion mode, you might get a PDF so "big" that Preview or Acrobat Reader might not be able to handle. Namely, preview might show a blank or distorted PDF in Sierra and High Sierra, and Acrobat Reader might display the page trimmed in OS X 10.9 and above, or in Windows.
The solution to this problem is to enable the "Use Pagination option" in WebSnapperPro Preference settings, or alternatively use an image format instead of PDF (e.g. PNG). Or, you can use Google Chrome to open the PDF, as it is the only engine for OS X that is able to properly handle these PDFs.
Missing images or content in the webpage: This started in Sierra and continues in High Sierra. The only fix is to use Image Conversion Mode instead of Vector Conversion Mode in WebSnapperPro > Preferences > Snapshot.
I have this simple question:
Is WebSnapperPro able to make a text searchable PDF of this page exactly as it appears in my browser (Firefox 57 or Safari 11)?
If YES, I can give it try. If NO, then bye-bye for good. I use the Firefox built-in screenshot tool for years and I don't regret it, except may be that it produces a whole-page PNG and I would prefer a PDF with the web page text intact.
