<h2>Why compress a PDF to 300KB?</h2> <p>Many official portals — including scholarship sites, visa applications, recruitment platforms, and online exam systems — strictly cap PDF uploads at 300KB. If your file is even slightly larger, the form will reject it. Manually re-scanning or rebuilding the document wastes time. A targeted compressor solves the issue instantly.</p> <h2>What stays the same after compression?</h2> <ul> <li><strong>Readable text</strong> — words and tables stay sharp, not blurry.</li> <li><strong>Original layout</strong> — page count, margins, and order are preserved.</li> <li><strong>Searchable content</strong> — text remains selectable and copyable.</li> </ul> <h2>Tips to hit 300KB cleanly</h2> <ul> <li>If your PDF is mostly scanned images, choose a stronger compression level.</li> <li>For text-heavy reports, the standard preset usually reaches 300KB without quality loss.</li> <li>If a single image dominates the file size, reduce that image first, then re-export to PDF.</li> </ul> <h2>Privacy</h2> <p>Your PDF is processed locally in your browser. Files are never stored on our servers, so sensitive resumes, ID copies, or contracts stay private.</p>
