Convert the colors of PDF text and images into tones of a color
What is Color PDF ?
Color PDF is a free online tool that converts all the colors of a PDF content (images and text) into the gradient of a single color i.e., shades of blue. Also, can change PDF background color if white. If you are looking to color your PDF online, convert your multi-colors PDF into uni-color, or change PDF text or background colors into tones of a specific color such as red, then this is your tool. This is useful to re-color your QR-codes, stickers, or during printing when you are out of black ink but color ink is available. To print the document, just convert the PDF black color into one of the available color ink. With this free service, you can quickly and easily recolor PDF content. Notice that the service converts PDF pages into images, color them, then convert images back to non-editable PDF.
