Turn every page of your PDF black-and-white in your browser, for cheaper printing and a cleaner look.
Is this tool really free?
Yes. Every tool on this site is free, with no account or sign-up required.
Are my files uploaded to your servers?
No. All processing happens in your browser, so your files never leave your device.
Is the text still selectable after conversion?
No. Pages are re-rendered as grayscale images, so the output is image-only. Use it for printing and reading, not for copying text.
Grayscale turns every page of your PDF black-and-white in your browser. Pick standard or high-definition output quality, then convert. The result prints cheaper and looks cleaner on paper, and your original color file stays untouched.
High-definition keeps small text and fine lines sharper. Standard makes smaller files. Pick high-definition when the pages hold detail that must stay readable.
Grayscale output is a picture version of each page, so text in the result cannot be selected. If you need selectable text, keep the original color file.

Which quality should I pick?
High-definition for small text and fine lines, standard for smaller files.
Can I still select text afterwards?
