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.

  • Building W-9 Crafter
    I first started building the app in the browser, using PDF.js and Download.js to take a PDF and edit it, and then download it to your computer. - Source: dev.to / 22 days ago
  • How to Write a Cold Email
    I'd think opening a PDF in your browser would be at the same risk-level you associate with going to any random URL. On Firefox at least, I'm pretty sure the built-in PDF viewer is simply JS parsing and rendering the PDF anyway -- nothing with elevated permissions: https://mozilla.github.io/pdf.js/. - Source: Hacker News / 5 months ago
  • PDF Chat with Node.js, OpenAI and ModelFusion
    We use Mozilla's PDF.js via the pdfjs-dist NPM module to load pages from a PDF file. The loadPdfPages function reads the PDF file and extracts its content. It returns an array where each object contains the page number and the text of that page. - Source: dev.to / 8 months ago
  • Printing as PDF: Chromium takes ages and 5Mb, while Webkit is super fast and light
    I’ve been using pdf.js before, worked quite well. Source: about 1 year ago
  • Pdf files and Javascript
    If you want a 'safe' way to read PDFs use Firefox, they have their own web module to render PDFs. Source: about 1 year ago

  • EPUB 3.3 becomes a W3C recommendation

  • Are there any good PDF viewers for large (10Mb+) datasheets that can save search results in the actual PDF, and take notes on the PDF?
