We just released a new major version for PDF Reducer. With an even more efficient compression rate and full PDF/A-4 support, version 4 provides you with the best technologies available.

New features and improvements

For this new major release, our team focused on improving the PDF Reducer compression rate and implementing full support for PDF/A conversion.

We’ve also updated our user guide and version history page with the v4 changelog.

Improvement of the MRC engine

ORPALIS PDF Reducer includes many different compression engines to give you the best results depending on your specific document. For instance, a scanned PDF, a text PDF, and an image require different technologies to obtain the best results.

The MRC (Mixed Raster Content) technology is particularly suitable for significantly reducing the size of complex PDF documents. By complex documents, we mean PDF files that include text, graphics, and images all together.
Learn more about MRC compression.

Remember that MRC is ONE of the many compression techniques included in PDF Reducer!

Improvement of the PDF/A support

PDF/A-4

For users looking for long-term archival of their electronic documents, PDF Reducer offers the possibility to save as the ISO standard  PDF/A (ISO 19005).
With version 4, all PDF/A versions and conformance levels are supported, including the latest PDF/A-4, PDF/A-4e, and PDF/A-4f.

What are the benefits of PDF/A-4?

We wrote two blog articles on the AvePDF website (the free web app we develop at ORPALIS) that explain everything you need to know about PDF/A and PDF/A-4.
