How does PDF compression work?

PDF compression reduces file size by optimizing images, removing unnecessary elements, and using efficient encoding. Our tool offers multiple compression levels to balance file size and quality.

Will compression affect my PDF quality?

With proper settings, compression can significantly reduce file size with minimal quality loss. Our 'Lossless' option maintains original quality while still reducing file size through optimization.

What is the maximum file size I can compress?

There are no strict limits, but very large files may take longer to process. The tool works best with PDFs under 100MB for optimal performance.

Are my files secure during compression?

Yes, all processing happens locally in your browser. Your files are never uploaded to our servers, ensuring complete privacy and security.

What compression options are available?

You can choose from Normal (balanced), High Compression (smaller files), or Lossless (best quality) modes. Additional options include image quality adjustment, font optimization, and target file size settings.
