PDF to Greyscale — Frequently Asked Questions
When should I convert a PDF to greyscale?
Before printing on a monochrome printer, before submitting to portals that require greyscale scans, or when you want a cleaner look without color distractions. Greyscale files are also smaller than their color originals in many cases.
Will the text still be selectable after conversion?
No. The tool rasterizes each page to an image and recolors the pixels, so the resulting PDF is image-based. Text is not selectable or searchable. If you need selectable text, print to PDF with a greyscale-only printer driver instead.
Is this true greyscale or just desaturated color?
True greyscale using the standard Rec. 601 luminance formula (0.299R + 0.587G + 0.114B). Each pixel becomes a single brightness value, which is how professional greyscale conversion is done.
Why does the output look softer than the source?
Raster conversion samples each page at a fixed resolution. Increase the render quality slider for crisper output at the cost of a larger file.
