Frequently Asked Questions

Does my PDF get uploaded?
No. Each page is drawn and converted to grayscale entirely in your browser, on your own device. Your PDF is never sent to a server, never stored, and never seen by us. Safe for confidential construction drawings and NDA work.
Will the text stay selectable after converting?
No, and that is worth knowing up front. To guarantee true grayscale on every printer, each page is rebuilt as a grayscale image, so live text becomes part of the picture. That is exactly what you want for predictable black and white printing, but if you need the words to stay selectable, keep your original color file too.
Why convert to grayscale before printing?
Color toner and ink are expensive, and many office printers handle a clean grayscale file more predictably than a color one. Converting first means every page prints in consistent shades of gray, with no surprise color draws and lower cost on long drawing sets.
Is it free, with no watermark?
Free, no signup, no email, and no watermark. A small thank-you tool from the team behind Ncored, the fast desktop PDF app for heavy AutoCAD, Revit, and ArchiCAD drawings.
