Free PDF Compression Tool

Our compression algorithm intelligently reduces file size while maintaining document quality as much as possible. The degree of quality loss depends on the compression level you choose. Text and vector elements are preserved at all levels, but image quality within the PDF may be reduced at higher compression settings. For documents with complex imagery, using the "Low" or "Medium" settings will provide a good balance between file size reduction and quality.

The best compression level depends on your specific needs. Use "Low" when quality is critical but you still want some size reduction. Use "Medium" for a balanced approach suitable for most documents. Choose "High" when smaller file size is more important than perfect image quality. The "Maximum" setting is best for text-heavy documents or when file size is the top priority.

The compression rate varies depending on the content of your PDF. Documents with many high-resolution images typically achieve greater size reductions (often 70-90%) compared to text-only documents (typically 20-50%). PDFs that have already been compressed may see more modest improvements. Our tool analyzes your document to apply the most effective compression techniques for its specific content.

Yes, we take your privacy and document security very seriously. Your PDFs are processed securely on our servers and are automatically deleted after compression is complete. We don't store or access the content of your documents beyond the time needed for processing, and all data transmission is encrypted using secure HTTPS connections. Your document content is never shared with third parties.
