Color files are expensive to print and often large in size. Here is why converting to black and white makes your files more efficient.
Convert color-heavy PDF into crisp black and white before hitting print. This instantly saves expensive color toner and reduces costs.
Color data adds unnecessary bulk to digital files. Stripping out the full color palette instantly optimizes and shrinks the file size.
Many courts and official institutions strictly require black-and-white submissions. Instantly neutralize colored fonts or logos.
Turn distracting background images to black and white, while keeping your charts, highlights, or colored text in full color.
Many archives, fax systems and document management platforms require black and white. Convert and the whole file complies.
Architects and designers need cheap test prints of blueprints. Grayscale your images to print drafts without wasting resources.
Color in a PDF is stored per element, text, vector graphics and images each carry their own color data. FynePDF converts that data to shades of gray using luminance weighting, which keeps light and dark relationships looking natural rather than washing everything to the same mid-tone.
Text, graphics and images all convert to gray. The standard choice for printing and archiving.
Photos and graphics turn gray while colored text and highlights stay as they are.
Removing color data typically reduces file size, with image-heavy documents shrinking most.
