What you need

Steps

  1. Download your PW notes as a PDF from the app or website and save them in one folder on your computer.

  2. Open a PDF editor that can change the page background, such as PDNob, or use a free online PDF colour inversion tool in your browser.

  3. Load the dark PDF into the tool and find the background or page colour setting.

  4. Change the background from black to white and set the text to black so the notes become readable on paper.

  5. Check a few pages to make sure diagrams and highlighted text are still visible after the colour change.

  6. If you have several PDFs, use the merge option in the same tool to combine them into one file.

  7. Open the print dialog and choose the option to print multiple pages per sheet, such as 2 or 4 slides per page, to save paper.

  8. Set the printer to grayscale or black and white and print a single test page before printing the full set.

Tips and common mistakes

Print one test page first to confirm the inverted colours look right before running the whole document.

Printing 2 or 4 slides per page cuts paper use and keeps the text large enough to read.

Keep the original dark PDF as a backup in case the converted file loses details.

The same colour change method works with Unacademy, Allen, Aakash and other EdTech PDFs.

Questions

Can I do this without paid software?

Yes. Free online PDF tools in a browser can invert colours and merge files, though some limit file size or daily use.

Will the diagrams still look correct after inverting?

Most line diagrams convert fine, but coloured images may look odd. Check a few pages before printing the whole set.

Does this work on a phone?

Yes, if the PDF tool runs in a mobile browser. Printing from a phone needs a printer app or a wireless printer.
