Here is a free tool to online convert PDF to grayscale. Its name is “Convert PDF to Grayscale Online“, which completely suits it. You can include text as well as PDF images to convert your PDF file to grayscale. You also have the choice to convert only text to grayscale and exclude images from converting them to black and white images. If you don’t want text as grayscale, then you can enable the option to convert PDF text to black color. So, this simple online tool has brought some useful options to convert PDF to black and white PDF.
This tool lets you upload PDF file from PC, Google Drive, Dropbox account, or you can also add URL of an online PDF to convert it to grayscale. Your PDF file is also deleted automatically from servers after 5 hours. Or else, you can also manually delete PDF file after downloading it to your PC. The free version of this tool has some limitations, but I guess that is sufficient for normal usage. In its free version, it can convert a 50 MB PDF file or 200 pages and 3 conversions per hour. Also, only one PDF at a time can be converted to grayscale. So, there is the limitation, but that won’t stop you from converting a colored PDF to grayscale PDF.
Above you can see a PDF file converted to grayscale using this tool.
