Convert a colour PDF to black and white for cheaper printing and smaller size — text stays sharp and selectable.
Frequently asked questions
Why convert a PDF to grayscale before printing?
Printing in black and white avoids colour ink or toner charges at print shops and offices, and the file usually gets smaller too.
Will text still be searchable?
Yes, with "Keep text". Colours are swapped for their gray equivalents in place, so fonts and text stay real. Gradients and spot colours may stay coloured — use "Flatten pages to images" for a guaranteed gray result.
Is Grayscale PDF (black & white) free?
Yes. Grayscale PDF (black & white) is free to use. You get 3 free conversions a day without an account, and unlimited use when you sign in with Google.
Are my files uploaded?
No. The conversion runs inside your browser, so your files stay on your device and are never sent to our servers.
Does it work on mobile?
Yes. PixKaro works in Chrome, Safari, Edge and Firefox on Android, iPhone, Windows and Mac.
