How to use Invert PDF Colours
- Choose a PDF.
- Pick Keep text (blend layer) or Image copy (night, invert or sepia).
- Select the button and download the new PDF.
What to expect
A new file is created. Your original files are never modified.
- Keep text inverts photos and logos too, so pictures look like negatives.
- The blend layer is part of the file. A viewer that ignores PDF blend modes would show the original colours; Chrome, Firefox, Edge, Safari and Acrobat support it.
- Image copy removes selectable text, links and forms.
Frequently asked questions
How do I make a PDF dark mode?
Choose a PDF and select Invert colours. With Keep text, every colour is inverted by a blend layer and the text stays selectable and searchable. The Image copy method instead saves night or sepia pages as pictures.
Is this the same as my reader’s dark mode?
No. A reader’s dark mode only changes how it looks to you. This tool saves a new PDF with the inverted look, which you can send or print (white text on black uses a lot of ink).
Is my PDF uploaded anywhere?
No. The PDF is processed by JavaScript in your browser. Only the website's own code and assets are downloaded, and you can check this in your browser's network panel.
Do I need to create an account?
No. Every tool works without sign-up or login.
Is it safe for confidential documents?
Files are processed locally in your browser and never uploaded. Close the tab or select Clear to release them from memory.
