        <h3>⚠️ Reality Check for Text PDFs</h3>
        <p><strong>Browser JavaScript CANNOT effectively compress text-heavy PDFs because:</strong></p>
        <ul>
            <li>Text PDFs are already highly efficient (vector text, embedded fonts)</li>
            <li>Real compression requires font subsetting, stream optimization, duplicate removal</li>
            <li>Converting text to images makes files 5-10x LARGER</li>
            <li>Your 10MB, 3075-page PDF is already well-optimized at ~3.3KB/page</li>
        </ul>
        <p><strong>This tool will:</strong> Remove metadata, optimize structure, compress any embedded images.
            <strong>Expected savings: 5-15%</strong></p>
