Grayscale PDF
Colour PDFs to black-and-white for printing.
Runs on your device. Files are never uploaded.
Every page is re-rendered in grayscale at the resolution you pick, which guarantees that nothing in colour is left — ideal for printing on a mono printer or saving colour ink.

Questions
Will text stay selectable?
Pages are rebuilt as images, so text is no longer selectable. Keep the original if you need to copy text later.
Are my files uploaded to a server?
No. The tool runs in your browser using your own device. Your file is never sent to us or anyone else — you can even disconnect from the internet after the page loads.
Is it really free?
Yes. There is no account, no watermark and no daily limit.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device memory — a modern phone or laptop handles files of several hundred MB.
