Frequently asked questions
How do I make a PDF black and white?
Upload here. Ghostscript strips all color information and outputs a clean grayscale PDF, ready to download in seconds.
Why convert a PDF to grayscale?
Cheaper to print on black-and-white printers. Smaller file size in most cases. Required for certain publishing, legal, or archiving workflows.
Will it affect text quality?
No. Text stays sharp and fully readable. Only the color data is removed; layout and content are unchanged.
Does it reduce file size?
Usually yes, especially for PDFs with color photos or graphics. Text-only PDFs see less reduction.
Is the conversion reversible?
No. Color information is permanently removed. Keep the original if you need color later.
Do I need to sign up?
No account required. Guests get one conversion per day; free accounts get 10.
Is there a file size limit?
50 MB per file.
Is my file safe?
Your file is processed in memory and deleted the moment your download starts. Nothing is stored.
