About PDF Compression
Large PDF files can be problematic for email attachments, web uploads, and storage. Our PDF compressor reduces file sizes significantly while preserving document quality and readability.
The compression algorithm optimizes images, removes redundant data, and streamlines the PDF structure. You can choose from three compression levels: Low (best quality), Medium (balanced), and High (smallest size).
Text in your PDF remains sharp and readable at all compression levels. The tool is particularly effective for PDFs with many images, where it can achieve size reductions of 70-90%.
For documents with scanned pages, our compressor applies specialized optimization that reduces size while maintaining OCR text if present. Vector graphics and fonts are preserved accurately.
The compressed PDF is fully compatible with all PDF readers and maintains interactive elements like links, forms, and bookmarks.
