Our tool optimizes the internal structure of your PDF document. This includes streamlining objects, removing redundant data, and sometimes apply lossless compression to images, resulting in a smaller file size without affecting visual quality.

Our PDF compressor focuses on optimizing the file\'s internal structure to achieve the smallest possible size without loss of quality. Text and images should remain clear and readable.

Absolutely. With PDFClear, your privacy is paramount. All PDF compression operations are performed locally in your web browser. Your sensitive files are never uploaded to any external server, ensuring complete confidentiality.

The tool currently applies a robust, standard level of structural optimization automatically. While there's a slider for compression level in the UI, it's provided for future enhancements and currently doesn't change the underlying compression algorithm, which prioritizes quality over aggressive size reduction.

PDFs containing unoptimized images, embedded fonts, or a complex internal structure will generally see the most significant size reductions. Documents already highly optimized or consisting mostly of simple text and vector graphics might have less room for further compression.
