PDF.js Express Key Flaws


PDF.js Express requires a paid REST API for flattening annotations, leading to unexpected additional costs.

Basic Feature Set

The platform falls short on providing features that go beyond elementary PDF workflows and applications.

Mobile Performance

Performance may lag, particularly on mobile devices.

No Technical Support

There’s no obligation for PDF.js Express to offer technical support, with all requests being directed to a community forum.

Product Support Uncertainty

Customers may encounter uncertainty over the long-term support for PDF.js Express by its parent company, Apryse.

Upselling Tactic

Apryse uses PDF.js Express as an entry-level tool to upsell its premium flagship products.
