Frequently asked questions

Why convert to grayscale?

Black-and-white printing is cheaper than color, and some portals and print shops ask for grayscale files specifically.

Will this affect image quality?

Pages are rebuilt as grayscale JPEG images, so text is no longer selectable or searchable. Sharpness stays close to the render resolution used in the browser.

Will the file get smaller?

Not necessarily — dropping color can help, but rebuilding pages as images can also make the file larger. Run Compress PDF afterwards if you need a smaller download.

Can I just print in black and white instead?

If your printer offers it, yes. Converting here is for when the grayscale version has to travel with the file — for an upload, an email, or a print shop.

Is my file uploaded?

No. The grayscale conversion happens securely in your browser.

Is this tool free?

Yes, it is completely free to use without an account.
