PDF Grayscale Converter — Color PDF to Black & White (Print-Friendly)

Color PDFs drink expensive ink — for drafts, handouts, and archiving, black-and-white is all you need. This print-friendly converter renders every page and rebuilds it as grayscale, or as true 1-bit-style black-and-white with an adjustable threshold for maximum ink savings. Everything happens in your browser; your document is never uploaded.

How it works

• Step 1 — Drop in a color PDF.
• Step 2 — Choose Grayscale (smooth tones, looks like the original) or True B&W (every pixel becomes pure black or white past your threshold — maximum ink savings), plus render DPI.
• Step 3 — Each page is rendered, converted pixel by pixel, and rebuilt into a print-friendly PDF. Note: pages become images, so text is no longer selectable — the trade-off for cheap printing.

Everyday uses

• Teachers — print class handouts without draining the color cartridge.
• Students — cheap draft prints of long readings and slides.
• Offices — archive-friendly B&W copies of invoices and contracts.
• Anyone — True B&W mode makes scanned documents dramatically smaller too.

Rule of thumb: use Grayscale for photos and diagrams you still want to read clearly; use True B&W with threshold ~140 for text-heavy scans.
