What is Foxit PDF Compressor?

Foxit’s PDF Compressor software provides businesses with fast, high-accuracy OCR equipped with the industry’s best document-to-PDF conversion & compression automation capabilities. The PDF software solution converts paper, scanned images, and born-digital content such as emails and Microsoft Office documents to text-searchable, compressed, fully optimized PDF and PDF/A files.

Unlike competitive solutions, Foxit’s PDF Compressor is designed efficiency-first, with more PDF features focused on automation, reducing unnecessary processing, and accelerating high-volume PDF document conversion than any other PDF software product.

PDF Compressor is ideal for organizations who need to convert thousands or millions of documents per year for archiving, compliance, accessibility, and for optimizing customer experience and core business process efficiency. The PDF solution is flexible enough to work well on backlogs of documents sitting in a repository (or that old warehouse, yikes!) as well as digital transformation of documents coming from your ongoing business processes.

OCR and Document Conversion Use Cases

PDF Compressor Software Features

Efficiency-First Digital Process Automation

The PDF Compressor software is designed for the business user with more features built around simple, automated, high-volume document processing than any other PDF solution, including intuitive job ticketing, watch folders, API, command-line, and remote management as an unattended Windows service. Manage conversion processes from one screen and prioritize different workflows quickly and easily.

Intelligent Text Layer Processing

Convert digitally born, electronic documents, and hybrid files to PDF and PDF/A faster and more accurately. PDF Compressor will uniquely detect pre-existing text layers and bypass the OCR phase, reducing unnecessary processing time and avoiding exposure to re-recognition errors that other solutions subject your workflows to.

Industry-Leading PDF Compression Rates up to 100:1

The software boasts unparalleled, industry-leading MRC compression that efficiently and correctly compresses paper and scanned image documents, up to ratios of 100:1 for color and 10:1 for black and white. Compressed documents enable faster email and access to documents, especially on mobile devices, for faster customer experience and easier information search for employees. In addition, organizations with large document repositories can greatly reduce local server and cloud storage costs.

Create Accessible, Tagged PDFs from Unstructured Documents Automatically

Prepare documents for accessibility compliance with advanced PDF auto-tagging. PDF Compressor can automatically create tagged PDF files from unstructured, scanned documents in addition to structured, electronic records.

Document Archiving with Comprehensive PDF/A Support

Convert paper, scanned images, and electronic documents to the ISO-compliant general archiving standard PDF/A-2u format or specialized subtypes such as PDF/A-1a, -1b, -2a, -2b, -2u, -3a, -3b, and -3u.

Batch Conversion and Multi-Threading for High-Volume Processing

With batch OCR and conversion, users can queue processing for numerous documents at one time, a much more effective high-volume alternative to less-effective PDF editors and free online conversion tools which typically only support one-at-a-time PDF conversion. Further, when enabled multi-threading allows users to process documents simultaneously (i.e. two cores process two documents at once, 32 cores process 32 documents at once) for highly scalable and stable document conversion workflows, up to billions of pages per year.

World-Class Customer Support and In-House PDF Expertise

When your organization chooses Foxit PDF Compressor, you get a highly responsive, multi-continent support team with a reputation for providing a brilliant customer experience. Even further, with an in-house team of experts in PDF technology & solutions to rely on at Foxit, your IT unit won’t have to worry about ineffective communication with third-parties and middlemen.
