How this works — and why it's private

Lossless rebuilds the PDF without touching text or vectors — perfect for reports and documents you still want to search and copy from. The other levels re-render each page as a high-quality image at the chosen resolution, then assemble a smaller PDF. Nothing is uploaded — the file never leaves your device.
