• Batch compression. Simultaneous processing of multiple PDF files. This feature enables the selection of numerous documents for compression in a single operation, saving time compared to individual processing.
• Image optimization. Reduction of embedded image sizes. It applies compression algorithms to graphics and photographs within the document, with options to adjust resolution and quality according to specific requirements.
• MRC compression. Mixed Raster Content compression technology. This method separates text and images into different layers, compressing each element with the most suitable algorithm to achieve maximum reduction ratios.
• Blank page removal. Automatic detection and removal of empty pages. The system analyzes the content of each page and suppresses those that contain no visible elements or data.
• Annotation removal. Elimination of comments and marks from the document. This function extracts annotations, notes, and markup elements that increase file size without contributing to the main content.
• JBIG2/JPEG2000 compression. Specialized algorithms for image compression. JBIG2 is applied to 1-bit images like scanned documents, while JPEG2000 handles photographs more efficiently than traditional formats.
• Font packaging. Optimization of embedded typefaces. The function analyzes which characters are actually used in the document and removes unused glyphs, reducing the portion of the file dedicated to fonts.
• Web optimization. Document configuration for online distribution. It adjusts the PDF's technical parameters so it displays correctly in browsers and downloads faster from web servers.
• PDF version selection. Compatibility with different format standards. It allows saving documents in specific PDF standard versions to ensure compatibility with legacy readers and systems.
• Overwrite policies. Conflict management with existing files. It offers options to automatically rename output files or overwrite documents according to operator preferences.
• Integrated explorer. File navigation with a tree interface. It facilitates locating and selecting documents in the file system through a visual representation of directories and subdirectories.
• Quality configuration. Gradual compression adjustments. It provides slider controls and predefined options to set compression levels that balance size reduction and quality preservation.
• Wizard mode. Step-by-step guided interface. It leads the user through the compression process with sequential screens for file selection, configuration, and save destination.
• Lossless compression. Size reduction while maintaining original quality. It applies algorithms that eliminate data redundancy without altering the visual or textual content of the document.
• Metadata processing. Document information management. It allows retaining or removing metadata, creation information, and PDF properties based on privacy needs or size reduction requirements.

The development of PDF-compress began in 2006 by ASCOMP Software, a German company specializing in productivity utilities. ASCOMP's engineers created the application to address specific document compression needs in business and professional environments. The programming was done primarily in C++ with system components in the C language, leveraging PDF development libraries to implement specialized compression algorithms. The software's evolution has continuously incorporated new compression technologies and has adapted to changes in PDF format standards.
