Frequently asked questions
Can the text still be selected afterwards?
No. Each page becomes a grayscale image, so the text is no longer selectable.
Which quality should I choose?
“Normal” is fine for printing most documents; “High” is sharper but makes a bigger file.
Is PDF to Grayscale free to use on Toolkoa?
Yes, the PDF to Grayscale tool is 100% free, unlimited and requires no sign up or installation.

No. Every operation on Toolkoa is processed privately and locally, directly in your own browser.
Do I need to install anything to use PDF to Grayscale?
