Dark-themed presentations print terribly—pages guzzle ink and text bleeds. Invert the colors before printing and you'll save cartridges and get cleaner output. CrispPDF's Invert tool flips every color in one click.
Upload the PDF and download a version where black becomes white, white becomes black, and everything in between shifts accordingly. For reading at night, inverted colors are easier on the eyes. For printing, inverted dark slides become ink-efficient white pages.
Because processing happens in your browser, your files stay private. After inverting, explore related tools: compress the result, add page numbers, or convert to grayscale for even cheaper printing.
