Compressing your PDF...
Reduce file sizes dramatically while preserving perfect quality
Our intelligent compression technology shrinks PDF files up to 90% without compromising text clarity or image quality. Perfect for email attachments, web uploads, or freeing up storage space. Whether you're working with scanned documents, image-heavy reports, or text-based files, our compressor delivers optimal results every time.
Unlike basic tools that simply downgrade quality, our solution analyzes document content to apply the most efficient compression method. Choose between three precision levels or let our smart algorithm automatically determine the best balance between size and quality.
Advanced algorithms reduce file size while maintaining crisp text and clear images at any zoom level.
Automatic image downsampling with adjustable DPI settings (72-300) for perfect balance.
Compress hundreds of files simultaneously with consistent settings across all documents.
Files processed in your browser - no uploads to servers for maximum privacy protection.
Our compression engine supports all PDF versions from 1.4 through 2.0, handling files up to 1GB in size. Advanced features include font subsetting to remove unused characters, image recompression with lossless options, and removal of redundant document elements.
For professional users, we provide detailed compression reports showing exactly what was optimized and by how much. Security settings remain intact during compression, and optional watermarking is available for processed files. The tool automatically detects and preserves text selectability and searchability.
