About this tool

Some print shops, exams, and government agencies require black-and-white documents. At home, printing in grayscale saves your color ink.

Frequently asked questions

Can I still select the text?

No. To make sure all color is removed, including from photos and charts, each page is converted to a grayscale image at your chosen resolution. If you need searchable text, run OCR on the PDF afterward.

Which resolution should I choose?

150 DPI is great for reading and everyday printing. Use 300 DPI for very small text or professional printing.

Are my files uploaded to a server?

No. This tool runs entirely in your browser: your file is read and processed on your device, and not a single byte is sent over the internet. You can even disconnect from the internet after the page loads.

Is it really free? Is there a daily limit?

It's free with no daily limits. Processing happens on your device, so there's no per-use cost and no need to limit you.

Does it work on phones?

Yes. The site works in any modern browser on Android, iPhone, Windows, Mac, and Linux—no installation needed.
