Understanding Our PDF Compressor Pro

PDF Compressor Pro helps reduce PDF file sizes by converting each page into an optimized JPEG image (rasterization). This method can be very effective for PDFs containing large, uncompressed images.

Key Considerations & Trade-offs:

  • Rasterization Process: Text and vector graphics are converted into pixels. This is fundamental to how this tool achieves compression for certain PDF types.
  • Visual Quality: Sharpness of text and line art will decrease. The extent depends on the chosen DPI and Quality settings. Lower settings mean smaller files but more noticeable quality loss.
  • Loss of Text Functionality: Text in the output PDF will NOT be selectable, searchable, or copyable. Accessibility for screen readers will be significantly impaired.
  • File Size Variation:
    • Effective for: PDFs with high-resolution images, scanned documents, or complex graphics.
    • May Increase Size for: PDFs that are primarily text, contain highly optimized vector graphics, or are already very small. In such cases, try the lowest DPI/Quality settings or this method may not be suitable.

Recommendations for Use:

  1. Upload your PDF. Note any initial warnings if your PDF seems text-heavy.
  2. Start with Medium Quality and 120 DPI. For text-heavy PDFs, try 72 DPI and Low Quality.
  3. Consider Grayscale for significant additional size reduction if color is not essential.
  4. Review the pre-compression disclaimer carefully.
  5. After compression, compare the output file size and visually inspect the quality. If the size increased or quality is unacceptable, try different settings or this tool may not be optimal for your specific PDF.

Experiment with settings to find the best balance for your needs!
