Grayscale PDF

Converts every page to black and white for cheaper, consistent printing. Pages are re-rendered as 150 DPI images, so text stops being selectable — the desktop app converts colors while keeping the document searchable.

This tool runs entirely in your browser — nothing you type or open here is ever uploaded. You can disconnect from the internet after the page loads and it still works.
