Questions
Is Grayscale PDF free in PDFMoose?
Yes. It is free in PDFMoose, with no account, no watermark and no daily task limit.
Are my files uploaded when I convert a PDF to grayscale?
No. The work happens entirely in your browser, so your file stays on your device and is never uploaded.
Will grayscale make the file smaller?
It can, but it is not designed for that. Use Compress PDF if file size is your goal.
