Convert PDF to Grayscale Before Printing

Printing a PDF in colour uses several times more ink than printing in black and white. Converting your PDF to grayscale before you print is one of the fastest ways to cut printing costs — especially for lecture notes, reports and scanned documents.

রঙিন PDF প্রিন্ট করতে সাদা-কালো প্রিন্টের চেয়ে অনেক বেশি কালি লাগে। প্রিন্টের আগে PDF গ্রেস্কেলে রূপান্তর করলে কালি ও খরচ দুটোই কমে।

Quick tip: For most student notes and office documents, grayscale printing looks almost identical to colour — and costs significantly less per page.

Grayscale vs Black-and-White: What Is the Difference?

Grayscale preserves shades of grey, so photos, charts and gradients still look natural. Black-and-white (1-bit) converts everything to pure black or white with no grey tones. For text documents, black-and-white is fine. For PDFs with images or charts, grayscale is better.

Does Grayscale Work with Pages-Per-Sheet Printing?

Yes. Combining grayscale with a 4-pages-per-sheet layout is the most cost-effective way to print PDFs. You save both ink and paper at the same time.
