Software to Compress & Reduce PDF File Size
Autobahn DX has replaced PDF Reducer! Efficiently compress large volumes of documents and create automated workflows to significantly reduce file sizes while preserving quality.
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.
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 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, separates text, finds similar bitmap sections and makes optimized recompression.
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.
Input file formats
With PDF Reducer you can downsize a large variety of images and documents. Nearly 100 input files formats are now available besides PDF, including raster images formats such as TIFF, JPEG, PNG, JPEG 2000 and RAW camera formats.
PDF/A conversion
PDF Reducer version 4 introduces PDF/A conversion support. Once documents are processed, PDF Reducer offers the possibility to save as PDF/A, the ISO standard for long-term archival of electronic documents (ISO 19005). All PDF/A versions and conformance levels are supported, including the latest PDF/A-4, based on PDF 2.0.
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 actions 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.
Drag’n drop support
Do it fast, don't mind Windows Explorer.
Language & Interface
Default user interface language in ORPALIS PDF Reducer is English. Based on your Windows language settings, ORPALIS PDF Reducer automatically displays the localised version of the interface, if it exists among ORPALIS PDF Reducer translated interface versions. Currently, available languages for ORPALIS PDF Reducer interface are: English and French.
