Frequently asked questions
How does Grayscale PDF work?
Each page is rendered, converted to grayscale, and rebuilt as a new PDF. Selectable text becomes an image of the page.
Is there a page limit?
Yes, about 50 pages in the browser to protect memory. Split larger documents first.
Is Grayscale PDF free?
Yes. Free with no limits or watermarks, because everything runs on your own device.
Is my PDF uploaded?
No. All processing happens locally in your browser. Your document never leaves your device.
