•PDF compression has been an essential technology since Adobe created the PDF format in 1993.
•The average business document can be compressed by 50-90% without losing searchability or text selection capabilities.
•A single 100-page text-heavy PDF can consume up to 10MB of storage uncompressed, but with proper compression, it can be reduced to just 1MB while maintaining full text searchability.
•PDF is the most widely used document format globally, with over 2.5 trillion PDFs created annually.
•Efficient compression that maintains text as actual text (not images) saves storage space while ensuring documents remain accessible for search engines and screen readers.
PDF compression preserves searchability through several sophisticated techniques:
•Our advanced PDF compressor uses PDF optimization engine, implementing the PDF/A standard for long-term archiving while reducing file size.
•Our "searchable" compression specifically avoids rasterizing text into images, ensuring text remains selectable, searchable, and accessible to screen readers.
•We employ lossless DEFLATE compression for text streams and metadata, ensuring no information is lost during the compression process.
