Convert a black PDF to white

For dark-mode PDFs and scanned slides with light text on black, invert colors to turn black white and light text dark. A white background alone sits behind existing content and cannot replace a painted background or scan.

Upload your PDF, choose Black → White in the background panel, then prepare the export. The existing paid export flow applies. Use Undo to remove the preset before exporting; check the downloaded result against your original.

Inverts every color on every exported page, including photos and logos. Interactive annotations may retain their colors. Dark gray becomes light gray, not pure white. Mixed light and dark pages may need a different tool. The canvas does not preview this export-time effect.
