Why is pdfRest the best API to flatten PDF layers?

pdfRest offers the best solution for flattening PDF layers, because it reduces file complexity, prepares PDFs for print, and streamlines integration.

Reduce File Complexity

PDF layers can be helpful during the PDF creation process to keep related content separated and make it easy to apply further changes to each component.  Once the PDF is finished, no longer intended to be edited, and ready to distribute, separate content layers may not serve the same utility for the intended viewers of the document.  Flattening layers places all content together on one layer, which simplifies the document content and removes unnecessary complexity that can result in downstream workflow problems.

Prep for Print

Flattening PDF layers is one step that helps to ensure PDF content is ready to be printed consistently and reliably. While this step is not always required as part of a preflight print process, it helps to reduce the risk of problems associated with the incorrect use of layers.

pdfRest is built with tried-and-true Adobe® technology that has supported enterprise print operations for decades. Flattening layers with pdfRest reliably optimizes PDF documents for printing.

Simple and Streamlined

Flattening layers is a complex operation, but you shouldn't have to dive into all the nuances of the PDF file format to achieve the results you're looking for. Let pdfRest do all the heavy lifting for you!

The process is simple - just pass in a PDF with multiple content layers and receive back a PDF with all content flattened to one layer. Results are consistent and reliable, helping you streamline the process to optimize your files for distribution.
