Color laser toner costs several times more per page than black. A 40-page report with colored headers, printed 30 times for a meeting, quietly burns through a color cartridge that grayscale would never have touched.
Converting in the browser
The Grayscale PDF tool converts every page to shades of gray locally, with a preview before download. Send the grayscale version to the office printer and keep the color original for screens.
Two benefits, one conversion
Printing cost: the printer receives no color data, so it cannot spend color toner — no more relying on everyone remembering to pick “print in grayscale” in the driver. File size: color scans store three channels of data; collapsing to one channel plus a compression pass often cuts scan-heavy files in half or better, which helps with email attachment limits.
Check before you commit
Grayscale is destructive to meaning in some documents: charts that distinguish series only by color become ambiguous, and highlighted text loses its emphasis. Scan the preview for color-dependent content first. If only certain pages need color, extract them, grayscale the rest, and merge back together.
