PDF Grayscale

Solution to save maximum printing ink budget for the office

Most presentation documents, textbooks, or market analysis reports are designed with lots of bright colors, hidden backgrounds, and complex charts. When you take this document to an office printer or photocopy shop: if you choose a color printing order, the cost will be 5 to 10 times more expensive than regular black and white printing. On the contrary, if the printer automatically processes the colors, text that is light yellow, orange or green is often printed as dull gray, very painful to the eyes and difficult to read.

iTools' PDF to Black and White (Grayscale) Converter tool helps you pre-process the color of the document before printing, ensuring bold black text and saving every drop of precious ink.

In-depth color optimization

• Grayscale Standardization: Converts all RGB and CMYK color ranges into a single gray channel (Single Gray Channel), helping printer nozzles operate smoothly and saving maximum ink.
• Increase contrast (High Contrast B&W): Smart algorithm automatically forces text characters to pure black (#000000) and pushes light gray background areas to pure white, helping lettering stand out on the printed paper.
• Reduce file size significantly: By eliminating 3 color channels, the size of the PDF file will automatically reduce from 30% to 50%, helping to send documents via Zalo or email in the blink of an eye.
• Protect image resolution: Illustration photos in documents are converted into sharp black and white artistic photos, without broken grain or sticky black patches.
