Important Notes

Best Results on Image-Heavy PDFs: The tool achieves the greatest file size reduction on scanned documents, reports, presentations, and PDFs containing a large number of embedded images.
Limited Impact on Text-Based PDFs: Documents that primarily contain text, vector graphics, or already optimized images may show little to no reduction in file size.
Image Quality Trade-off: Higher compression levels may result in a reduction in image quality. Users should review optimized documents to ensure they meet their intended use.
Document Content Preserved: The tool is designed to compress embedded images while maintaining the original document structure, page order, and formatting.
Processing Time Varies: Optimization time depends on the size, number of pages, and image content within the PDF.
Review Before Submission: For regulatory, legal, clinical, or archival purposes, users should verify that the optimized document remains compliant with any applicable quality or submission requirements.
No Guarantee of Specific Compression Ratios: File size reduction depends on the original document characteristics and may vary significantly between PDFs.
Backup Recommended: Retaining a copy of the original PDF is recommended before performing optimization, especially for important or irreplaceable documents.
