Convert PDF to grayscale online
Strip color from any PDF for cheaper printing or smaller file size. ICC-corrected grayscale conversion.
Color printing is expensive. PDFs in color also tend to be larger files. Convert PDF to grayscale via Ghostscript with proper ICC color management — text stays crisp, photos become high-quality grayscale, and the file usually shrinks meaningfully.

Frequently asked questions
Will text stay sharp?
Yes — text is converted to a single black channel, perfectly crisp. Only photographic content is converted to grayscale tones.
How much smaller will the file be?
Photo-heavy color PDFs often shrink 30-50% in grayscale. Text-only PDFs see less reduction since they were already monochromatic at the content level.
