How to Invert PDF Colors
Need to invert the colors of a PDF? ToolifyPDF is a free online PDF color inverter that turns white pages black, black text white, and every other color into its opposite. It's perfect for reading documents in dark mode, reducing eye strain at night, or creating a negative of a drawing or scan. The text stays real text you can select and search, and the file size barely changes because nothing is turned into an image. Invert one PDF or up to 30 at once, with no software to install and no account needed.
Every Color Inverted
White becomes black, black becomes white, and every color turns into its opposite: red becomes cyan, blue becomes orange, and so on.
Text Stays Text
The pages are not turned into pictures. Your text stays sharp, selectable, and searchable, and the file stays about the same size.
Invert 30 PDF Files at Once
Upload up to 30 PDF files, up to 200 MB each, rotate any that are sideways, and download them together in a ZIP file.

FAQ
How do I invert the colors of a PDF?
Upload your PDF to ToolifyPDF, click "Invert Colors", and then click "Download". You get a new PDF where white is black, black is white, and every color is its opposite.
Can you invert colors on a PDF for free?
Yes. ToolifyPDF inverts PDF colors for free, with no sign-up and no watermark. You can invert up to 30 PDF files at once, up to 200 MB each.
Can I invert PDF colors in Adobe Acrobat?
Adobe Acrobat can show a PDF with different colors on screen, in its accessibility settings (Replace Document Colors), but this only changes how the document looks in Acrobat on your computer. It doesn't change the file itself. To get a PDF with inverted colors that looks the same everywhere, use our free PDF color inverter.
Will the text stay sharp and selectable?
Yes. The colors are inverted without turning the pages into pictures, so text stays sharp at any zoom level, and you can still select, copy, and search it.
What happens to photos and images?
They are inverted too, like a photo negative: light areas become dark and colors turn into their opposites. That's what makes a page fully readable in dark mode.
Is an inverted PDF good for printing?
Usually not. A page with a black background uses a lot of ink. Inverted PDFs are made for reading on a screen. To save ink when printing, use our Grayscale PDF tool instead.
Can I convert the PDF back to normal colors?
Yes. Run the inverted PDF through the tool again: inverting the colors twice gives you the original colors back.
Can I invert the colors of a password-protected PDF?
Yes. Enter the password when asked, and the colors are inverted as usual. The inverted PDF you download has no password.
Are comments and form fields inverted too?
No. Comments, highlights added as annotations, and fillable form fields are shown by your PDF viewer on top of the page, so they keep their original colors. Everything that is part of the page itself is inverted.
Is it safe to invert PDF colors online?
Yes. Your files are uploaded over encrypted HTTPS connections and processed on secure servers. All uploaded and inverted files are automatically deleted one hour after processing, and we never share your documents with third parties.
Advanced Features
Beyond simply inverting colors, our PDF color inverter offers several useful features:
- Exact Inversion: Every color becomes its exact opposite, and inverting twice gives the original back.
- Real Text Kept: Text is not turned into an image, so it stays selectable and searchable.
- Small Files: The file size stays about the same as the original PDF.
- Password-Protected PDF Files: Enter the password and invert protected files.
- Rotate Before Inverting: Fix the orientation of any document before the conversion.
- Batch Conversion: Invert up to 30 PDF files at once and download them in a ZIP file.
💡 Pro Tip
Inverted PDFs are great for reading on a screen at night, but they use a lot of ink when printed. Keep your original PDF for printing, or use Grayscale PDF to save ink.
Privacy & Security
We take your privacy seriously. All file uploads and processing happen over encrypted HTTPS connections. Your files are automatically deleted from our servers after one hour, and we never store or share your documents with third parties. You maintain complete control over your data at all times.
