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.

You can choose between Basic (Web Optimization) and Good (Recommended Lossless Compression). The Good level provides the best balance of size reduction and compatibility.

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.
