Optimize PDFs for Fast Web Viewing with Linearize PDF

Why is pdfRest the best API to linearize PDF?

pdfRest offers the best solution for linearizing PDF documents, because it supports Fast Web View, simple application, and easy integration.

Linearize with Confidence

Unlike other APIs that offer PDF linearization solutions, pdfRest uses the same underlying technology that powers Adobe® Acrobat™ to optimize files for Fast Web View.

What can go wrong when you restructure all of the content in a PDF document with substandard technology? Do you really want to find out? Trust the original inventor of the PDF format to apply linearization the right way from the start.

Simple to Apply

Linearization is a complex operation, but optimizing your documents for online viewing shouldn’t require you to earn a degree in PDF technology. We’ve got you covered with the most streamlined process to apply linearization.

Select a file, give the output a name, and those are the only decisions you’ll need to make to prepare for the best PDF online viewing experience.

Easy Web App Integration

Linearization is most important when PDFs are intended to be served over a network connection for a web viewing user experience.

pdfRest’s Linearize PDF tool is ideally suited for this purpose, as the REST API design supports easy integration with any web application, no matter what languages or tech stacks are used under the hood.
