Print Lecture Slides
Print lecture slides for revision: 4 or 6 to a sheet, dark slides made light, free.
Print lecture slides for exam revision without wasting paper or ink. Add one lecture or a whole term of them, choose how many slides go on each sheet, and get one PDF that is ready to print. Dark slides, the white-on-navy kind that empty a printer cartridge, are turned light: the background becomes white and the text dark, while photos stay exactly as they are, and you can switch any slide back. You can also leave out title slides, drop blank pages, add lines for notes beside each slide and number the sheets. Everything happens in your browser, so your lectures never leave your device.

- Turn on double-sided printing as well, to halve the paper again.
How to print lecture slides
- 1
Add your lecture PDFs in the order you want them printed. Slides in PowerPoint? Save them as PDF first, as explained below.
- 2
Choose how many slides go on each sheet. The number of sheets for each choice is shown as you go.
- 3
Keep “Turn dark slides light to save ink” on, and pick any other options you want.
- 4
Press “Prepare for printing”, check the slides that were lightened, and download your file.
Slides in PowerPoint? Save them as PDF first
PowerPoint files can’t be opened in the browser, but every slide app saves a PDF in a few taps:
- PowerPoint on a computer: File › Save As (or Export) › PDF.
- PowerPoint on a phone: open the file, tap Share or the three-dot menu, and choose PDF.
- Google Slides: File › Download › PDF document. On a phone: the three-dot menu › Share & export › Save as › PDF.
- Keynote on a Mac or iPhone: File › Export To › PDF, or Share › Send a copy › PDF.
- Slides you received as a PDF, on WhatsApp or from your university’s website, can be added as they are.
When you would use it
Printing a whole term’s lectures before exams, several slides to a sheet.
Saving ink on dark-themed slides, which otherwise print as solid blocks of colour.
Making revision handouts with room to write notes beside each slide.
Sending one tidy, smaller file to the print shop instead of ten separate lectures.
What to expect
Lightened slides become pictures: their text can no longer be selected or searched in the PDF. The other slides keep their real text.
Colours stay recognisable but not identical: a yellow title prints as a darker yellow so it reads on white paper. If a slide doesn’t look right, switch it back to the original.
Slides get small: at 6 or 9 to a sheet, small print may be hard to read. Print one sheet first to check.
PowerPoint files can’t be opened here; save them as PDF first. Animations and speaker notes don’t come along.
Printing in black and white? Choose “Black and white” or “Greyscale” in your printer’s settings: that works better than changing the file.
Frequently asked questions
Is it free to print lecture slides here?
Yes. No sign-up, no daily limit and no watermark on your file.
Are my lectures uploaded?
No. The files are read and laid out inside your browser, on your device. Nothing is sent to us or anyone else.
How many slides per sheet should I choose?
4 per sheet is a good balance for most slides. To save more paper, print slides 6 per page: that suits slides with large text. 3 with note lines leaves room to write beside each slide, and 2 per sheet suits slides full of small print or detailed diagrams.
How does it save ink on dark slides?
It finds slides with a dark background and turns them light: the background becomes white, white text becomes dark, and coloured text and charts keep their colour, darkened just enough to read on white paper. Photos are left exactly as they are. Each changed slide is shown before and after, and you can switch it back to the original.
Can I print PowerPoint slides?
Save them as PDF first: PowerPoint, Google Slides and Keynote all do it in a few taps, as the guide above shows. Then add the PDF here.
Can I send the file to a print shop on WhatsApp?
Yes. Turn on “Make it smaller” before you prepare the file: pictures are made lighter while staying sharp enough to print, so the file is quicker to send.
Does it work with Arabic slides?
Yes. The order of slides on the sheet follows your slides’ own language: Arabic slides go right to left, with the first slide at the top right, and English slides left to right, even on the Arabic page. You can change it with “Order of slides on the sheet”. With note lines, the lines go on the left of Arabic slides.
What about double-sided printing?
Each choice shows how many sheets of paper you need when printing on both sides. With several lectures, “Start each lecture on a new sheet” keeps them apart, so each can be stapled on its own.
