Frequently Asked Questions

Will all colors be converted?
Yes. Every color element — text, images, backgrounds, graphics, and annotations — is converted to its grayscale equivalent. Pure black text remains black; colors are mapped to appropriate gray tones.
Is the original PDF affected?
No. The conversion creates a new grayscale PDF. Your original color file remains unchanged on your device.
Why convert to grayscale?
Common reasons: saving on color ink costs when printing, ensuring consistent output on monochrome printers, reducing visual distraction for document review, meeting submission requirements that specify black & white, and creating archive copies.
Does it affect text quality?
The grayscale conversion rasterizes pages to maintain color accuracy in the conversion. Text appearance is preserved, though it becomes an image rather than selectable text.

Save on printing costs, improve readability for document review, and create archive-ready versions of your PDFs — all with a single click in your browser.
