Why should I convert a PDF to grayscale?

Grayscale PDFs save expensive color printer toner and ink, significantly reduce file size for email, and meet strict legal and academic filing submission rules.

Are my document contents uploaded to external servers?

No. The pixel-level desaturation and PDF reassembly happen 100% locally in your browser memory using HTML5 Canvas and WebAssembly.

What is the difference between Grayscale and Pure B&W?

Grayscale uses 256 shades of gray preserving photo subtleties, while Pure B&W thresholds every pixel to pure black or pure white for maximum text readability.
