Converting a PDF to grayscale removes colour while keeping the full range of light-to-dark tones, so photographs still look like photographs. It is useful for cheaper monochrome printing, meeting submission requirements, or shrinking colour-heavy scans.
The conversion happens in your browser with no upload. Before relying on the result, check that nothing important was conveyed by colour alone. For more, see our grayscale guide.

Frequently Asked Questions
Is the text still searchable after conversion?
Grayscale conversion rasterizes pages (like Rasterize compression mode), so the text layer is replaced by an image. If you need searchable text in the output, run OCR on the result.
How much smaller will the file be?
Colour PDFs often shrink by 20-60% after grayscale conversion because colour channel data is removed.
