How to print without black ink?

This tool converts your PDF so that it will print in almost-black. It is easy to vary how much “black” the tool automatically converts. Pick a color and review the modified image. Download and print! You can choose a number of different target colors — maybe your color cartridge is out of black and green, but it has blue! Or red!

This will change all colors in your PDF, including:

  • fonts and text
  • images
  • graphics
  • pictures
  • lines
  • shapes
  • headings
  • titles
  • footnotes
  • captions
  • headers
  • borders

Print a form, shipping label, homework, and pictures when your printer runs out of ink!

If the above doesn’t work, try removing your black ink cartridge — sometimes this “tricks” your printer and makes it print black from the color cartridge!

What users say about the tool’s ability to convert PDFs into Color

Was out of black ink. Tried Photoshop and Lightroom. Couldn’t do what I wanted. Found this. Saved the day!


WOW your website saved me … **** *** black ink cartridge ran out after like 50 pages, and I needed a paper printed TONIGHT, and after searching for an hour on how to simply change the color of my pdf to blue, I found a link to your site in the comment section of a youtube video. Holy %@#!. Thank you.
