How to print Physics Wallah (PW) notes without wasting ink
PW class notes are usually exported straight from the teacher’s dark digital board: white and coloured handwriting on a black page. They are brilliant on a phone and painful to print — every page is almost solid black. Converting them first turns a cartridge-killing PDF into clean black-on-white notes.

What you’ll print from PW
Class notes (board PDFs)
Dark background — convert before printing. This is where the biggest saving is.
DPPs (daily practice problems)
Usually already white. Auto mode leaves them untouched, so you can run mixed PDFs safely.
Module / sheet PDFs
Typically print-ready. Use Pages per Sheet to fit 2 pages on one A4 side for revision.
Recommended settings for PW PDFs
- Which pages: Auto (only dark pages are inverted)
- Slides per sheet: 2
- Colour: Keep colour
- Clean background: On
Board notes are landscape and use large handwriting, so 2 per sheet stays very readable and halves your paper. Colour is kept because teachers use coloured pens to separate concepts — switch on black & white if your printer is mono.

Tips from students who print a lot
- Download the lecture PDF from the PW app or website first — this tool works on the PDF file, not inside the app.
- Batch a whole chapter: merge all class-note PDFs of one chapter, then convert once.
- For formula revision, extract just the summary pages and print them 4 per sheet.

Frequently asked questions
How do I print PW notes without wasting ink?
Download the class-notes PDF, choose it in the converter on this page and click Convert. Dark board pages become white with dark handwriting, and the new PDF downloads automatically. Print that file instead of the original.
Will the coloured handwriting still be visible?
Yes. Inversion keeps colours distinct — they shift to their opposite shade, so different pen colours stay different. If you want pure black text, tick “Black & white output”.
Does this work for Arjuna, Lakshya, Yakeen and Prayas batch notes?
Yes. It works on any PDF, whatever the batch. Padhle Beta is not affiliated with Physics Wallah — it simply converts PDFs you already have.
How much ink does converting PW notes save?
A dark page covers most of the sheet in toner; the converted page only prints the writing. For typical board-style notes that is roughly 50–70% less ink per page, and printing 2 or 4 per sheet cuts paper by half or more on top of that.
Does it work on my phone?
Yes. It runs in Chrome on Android and Safari on iPhone. Large PDFs (300+ pages) are faster on a laptop.
