Convert PDFs to Grayscale

We’ve released a new tool: converting PDF documents to grayscale. What it does is it converts all text and images inside the PDF to grayscale. In case you’re not sure what grayscale means, it’s something that used to be in full colours and is now represented by a range of grey shades from white to black, as used in a monochrome display. Use less (colour) ink when printingThe most common reason for converting a PDF document to grayscale is to consume no coloured ink when printing it.

It's like the center of our little pdf manipulation universe, it's the natural evolution and a complete rewrite of the pdfsam-console (the pdfsam component that provides all the pdf manipulation logic).

Feature highlight: Split pdf by bookmarks

Some pdf documents have an outline on the left side, listing chapters and subchapters. This outline acts as a list of bookmarks, usually you can click on a bookmark and navigate to that part of the pdf file. Splitting by chapters So, let's say we would like to split this pdf file and create multiple pdf files, each containing one separate chapter. Using the app's split by bookmarks feature you can do that.
