Open-source JavaScript library PDF.js is best known as Mozilla Firefox’s built-in PDF viewer. But for nearly a decade, it’s also served as a well-travelled entry-point into the PDF ecosystem. Hundreds of developers and integrators have leveraged PDF.js to embed PDF viewing capabilities in their applications and websites.
In recognition of PDF.js and all of its contributor community hard work, PDFTron recently introduced a complete guide to PDF.js, a comprehensive blog series packed with useful intelligence, videos, and infographics that detail PDF.js’s genesis, behavior, trajectory, and technical aspects.
In short: our guides help the market better understand PDF and PDF.js, improving their entry into the ecosystem, which helps us all.
Topics covered within the guide include:
- PDF.js’s support for the PDF specification including annotations, form filling, and signatures
- Ease of extending PDF.js with missing features
- Browser support and behavior
- Text select/text search UX
- Image quality at zoom
- Contributor community support
- Rendering behavior, performance, and reliability
- And much more
Additionally, in order to promote further interest in, adoption of, and, hopefully, contributions to PDF.js itself, we’ve developed a commercial solution, PDF.js Express. PDF.js Express augments PDF.js with additional annotation, form filling, and e-signature capabilities by wrapping a commercial React UI around the PDF.js rendering engine.
The complete guide to PDF.js is available on our website and includes detailed articles on subtopics such as PDF.js rendering accuracy and reliability. If you think any of these articles would be of interest to your customers, we’d be delighted if you’d share by linking from your website.
