About Grayscale PDF
Every colour in the document, in text, drawings and images, is converted to a shade of grey. The result prints predictably on black and white printers and meets submission rules that ask for grayscale.
Text stays text, so it remains selectable and searchable.
When grayscale helps
- Printing on a black and white printer, so colours turn into predictable greys.
- Submitting documents to offices that ask for grayscale scans.
- Checking that charts stay readable without colour.
Charts and colour coding
Colours with similar brightness, such as red and green, become almost the same grey. Check charts and highlighted text in the result before sending.

Questions
Will text stay sharp?
Yes. Text and vector graphics are converted to grey, not turned into images.
Does it make the file smaller?
Sometimes a little, when the PDF contains many colour images. For a real size reduction, use Compress PDF.
Can I undo it?
No. Colour information is removed. Keep your original file if you may need the colour version.
