ORPALIS PDF Reducer is a super fast and powerful PDF compression Software for general public and developers meant to help anyone to get existing PDF files reduced up to 80% more than concurrent products.
To achieve that, ORPALIS PDF Reducer provides different innovative and highly sophisticated size-reducing techniques which can be optionally applied by user selection:

Unrivaled lossless data re-compression

Innovative and highly sophisticated techniques which restructure existing content and apply the most effective compression scheme based on data type. Documents are printable and zoomable without loss of quality.
PDF Reducer is able to serialize several compression algorithms on images in order to (surpass) the limitations of some compression schemes.

Unrivaled lossless data re-compression

Remove unwanted or unused objects

You might have received PDFs containing additional, unwanted objects: let PDF Reducer remove them for you.

Remove unwanted or unused objects

Automatic color detection and layout analysis

Usually, scanning batches of papers under scanner's color-mode implies mixing together colored and B&W documents. PDF Reducer automatically identifies the B&W ones and encodes them as plain B&W thus dramatically reducing the file size.

Automatic ColorDetection

Raster images re-sampling and re-composing

Decrease un-necessary high resolution to dramatically reduce the file size without affecting the viewing experience.

Resampling and Recomposition

Content segmentation and optimal compression

Segments embedded images, separates text, finds similar bitmap sections and makes optimized recompression.

Content Segmentation

Fast web view support (linearization)

Add to your large PDFs the ability of being viewable for web-users even before the PDF file download is complete.

Fast Web Support

Input file formats
