The PDFTron Advantage


Optimized rendering means a better viewing experience. Stream individual pages or tiles without downloading the entire file to minimize bandwidth and memory footprint.


The PDF specification is very complex. Avoid costly surprises with the most compliant rendering engine built from the ground up and perfected at PDFTron over the last 20 years.


Developing the entire stack in-house has produced a track record of reliable and stable APIs that don’t break products with every update.


Start with just what you need and seamlessly add platforms/formats/features as your product grows. The most comprehensive platform ensures that all your needs will be met.


Adjust how your product looks and feels, and build a unique product with an open-sourced UI. Flexible and transparent licensing works great for both startups and established companies.


A single API across all platforms means a shorter learning curve, faster development, and easier maintenance. Code samples and tutorials make it easy to get up and running.


Cut your costs for bandwidth, storage, DevOps, and infrastructure with unique on-demand serverless viewing technology.


In case of an issue, talk directly to the expert PDF developers who built the PDFTron SDK. No broken phones!


Since PDFTron was built from the ground up you benefit from patent, copyright, and legal indemnity with full licensing transparency.

Testimonial profile
After evaluating the available options, it quickly became clear that we would give PDFNet a try. PDFNet more than met our needs for an affordable, flexible, and portable solution, which integrates well into our development system. Its comprehensive set of features and its unicode support in particular is impressive, and PDFTron's support staff have given us very helpful replies. We are looking forward to a productive collaboration.
