## FAQ

### Does grayscale reduce file size?

Yes. Removing color information can significantly reduce file size, especially for image-heavy PDFs.

### Does this preserve bookmarks and form fields?

Yes. Conversion to grayscale only re-encodes color spaces; bookmarks, form fields, and annotations all carry through unchanged.

### What PDF versions are supported?

Grayscale conversion works on PDF 1.0 through 2.0. Colour spaces in the input are remapped to DeviceGray on output.
