10 Best PDF Expert Alternatives for Various Tasks in 2022
Verdict: Okular is an open source and can be used free, which is probably its main advantage. At the same time, its basic functionality is meant to be not only highly competitive with PDF Expert but rather overcomes it because the letter can be used only under paid subscription. This PDF Expert alternative is one of the most all-in-one PDF readers, which is compatible not...

  • Signing PDFs
    If you mean signing as in "signing with your handwritten signature", you could use Okular () which easily allows you to do that. Filling out forms also works nicely. Source: 6 months ago
  • Alexandria: A minimalistic cross-platform eBook reader
    I was in a similar position lately until I found Okular. Have you tried it? https://okular.kde.org/. - Source: Hacker News / 9 months ago
  • Help with PDF's
    I would try Okular first, though, which is free and open source: https://okular.kde.org/. Source: 12 months ago
  • EPUB 3.3 becomes a W3C recommendation
    KDE's okular might be a good choice. I haven't personally used it for epub but I know it supports it. https://okular.kde.org/. - Source: Hacker News / 12 months ago

  • PDF rendering server-side using HTML 5 + CSS 3
    Are you looking for a way to render PDF's or produce them? If you want to produce PDF's, I've used https://pdfbox.apache.org/ successfully as well as https://itextpdf.com/ (potentially costs money). Source: 6 months ago
  • I interviewed Bruno Lowagie, who successfully commercialized his FOSS library, iText, between 2008 and 2018, for Code Code Ship: “Commercializing iText had a significant impact on the quality of the library”
    So, the case study would be an optional request/collaboration, but slapping your logo on their site (as seen on their home page just below the fold) is not written as optional. Say what you will about AGPL, but if you're a paying customer, this should be an easy provision to strike from the agreement if requested. They declined and our internal legal team refused to accept the agreement as a result and so we found... Source: about 1 year ago
  • How do i convert html file to pdf file using java(fx)?
    Not really a JavaFX question as JavaFX is a UI framework. Your question is therefore just related to Java. To answer that I've seen a similar feature from IText (https://itextpdf.com) or OpenPDF (https://github.com/LibrePDF/OpenPDF) as an open source alternative. Maybe take a look at those for a start and check if they provide you what you're looking for. Source: over 1 year ago
  • What enterprise wide solutions have you adopted as alternatives to digitally generating documents that are not PDF?
    As for generating PDF's themselves. You could start rolling your own service... Or maybe you could use something like this: https://gotenberg.dev/ Or maybe you use it as an inspiration and use the (F)OSS tools inside that box (look at the documentation) to roll your own service instead. Or - depending on the budget - you could go for a proprietary solution and go with e.g. Itext (https://itextpdf.com/en). Source: about 2 years ago
