How to invert a PDF in 3 steps

Frequently asked questions

• What does inverting PDF colors do?+
  Inverting a PDF swaps every color — white backgrounds become black and black text becomes white. The result looks like a dark mode version of the document. All content is preserved, only the colors change.
• Will inverting affect text quality?+
  No. The tool renders each page to a high-resolution canvas before inverting the pixel values. Text, images and layout are all preserved at full quality. The only change is the color of every pixel.
• Can I invert only specific pages?+
  Yes. Click "Select specific pages" and tap the page numbers you want to invert. The rest of the document stays in its original colors. Useful when only some pages have dark backgrounds.
• Is my PDF uploaded when inverting?+
  No. All processing happens in your browser using JavaScript and Canvas. Your PDF never leaves your device — no upload, no server, no data collection.
• Why invert a PDF to save printer toner?+
  Printing a page with a dark background requires a large amount of ink to fill the background area. By inverting the colors first, the background becomes white and uses almost no ink, saving significantly on toner costs especially for multi-page dark-themed documents.
• Can I see a preview before downloading?+
  Yes. After uploading, page 1 is shown side-by-side before and after inversion so you can see the exact result before deciding to download. The preview updates live if you switch to Select Pages and change whether page 1 is included.
