PDF Reducer Pro includes powerful, innovative, and sophisticated features developed by worldwide recognized experts in document imaging.

ORPALIS PDF Reducer Professional is a super fast and powerful PDF compression Software for the general public and developers meant to help anyone to get existing PDF files reduced up to 80% more than concurrent products.

To achieve that, The PDF Reducer provides different innovative and highly sophisticated size-reducing techniques that can be optionally applied by user selection.
  • Content segmentation and optimal compression.
  • Automatic color detection engine and layout analysis.
  • Embedded raster images re-sampling and re-composition.
  • Fast Web View support for sharing PDFs on the Web.
  • Removal of unwanted or unused objects such as annotations, form fields, bookmarks…
  • Unlimited batch processing.
  • Drag and Drop support for an ergonomic interface.
  • Multi-threading support to speed up the compression process.
  • Command-line interface support to take advantage of the features inside batch scripts or integrate them into custom applications.
Unrivaled lossless data re-compression
Innovative and highly sophisticated techniques that restructure existing content and apply the most effective compression scheme based on the data type.

Documents are printable and zoomable without loss of quality. PDF Reducer Pro is able to serialize several compression algorithms on images in order to (surpass) the limitations of some compression schemes.

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

Automatic color detection and layout analysis
Usually, scanning batches of papers under the 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.

Raster images re-sampling and re-composing
Decrease un-necessary high resolution to dramatically reduce the file size without affecting the viewing experience.

Content segmentation and optimal compression
Segments embedded images separate text, finds similar bitmap sections and makes optimized recompression.

Fast web view support (linearization)
Add to your large PDFs the ability to be viewable for web-users even before the PDF file download is complete.

Input file formats
With the app version 3, you can downsize a large variety of images and documents. Nearly 100 input file formats are now available besides PDF, including raster image formats such as TIFF, JPEG, PNG, JPEG 2000, and RAW camera formats.

Multi-threading support
Executes PDF processing via multiple, simultaneous and concurrent threads, decreasing processing time by using CPU resources most efficiently.

Command-line interface support
Automate PDF processing with commands without needing repetitive action control via the GUI (graphic user interface).

Unlimited batch processing
Executes PDF processing via multiple, simultaneous and concurrent threads, decreasing processing time by using CPU resources most efficiently.

Language & Interface
The default user interface language in ORPALIS is English. Based on your Windows language settings, It automatically displays the localized version of the interface, if it exists among ORPALIS PDF Reducer translated interface versions.

Currently, available languages for ORPALIS PDF Reducer interface are: English, French and Romanian.
