Is there a way to invert PDF colors using GIMP?

Inverting PDF colors using GIMP is a straightforward process that can enhance readability, especially for users who prefer a dark mode. This guide will walk you through the steps to invert colors in a PDF using GIMP, a free and open-source image editor.

How to Invert PDF Colors Using GIMP

To invert the colors of a PDF using GIMP, follow these steps:

1. Open the PDF in GIMP: Start by launching GIMP and opening the PDF file you want to edit. GIMP will prompt you to import the PDF, allowing you to select specific pages or import all pages.

2. Select the Page: Once the PDF is opened, choose the page you wish to invert. Each page will be imported as a separate layer if you import multiple pages.

3. Invert Colors: With the desired page selected, go to the menu bar and click on Colors > Invert. This action will invert the colors on the selected page, turning white to black and vice versa.

4. Adjust Levels (Optional): If the inversion does not meet your expectations, you can further adjust the levels by going to Colors > Levels. This allows for fine-tuning of brightness and contrast.

5. Export the Inverted PDF: After inverting the colors, export the document by selecting File > Export As. Choose your preferred file format, such as PDF, and save the changes.
