Projektor is a sophisticated Mac OS X application to present PDF slides in a smart way. This covers the case where you created your slides with LaTeX Beamer and therefore only have a PDF version of the slides. This application assists you presenting such slides. It disables sleeps of your Mac during presentation mode.

Auxiliary displays are automatically connected. The main and the external display are listed with their current resolution. If an external display is detected, its location in relation to the main display is shown.

For rehearsing purposes this application shows you the presenter view on your main screen, if no external display is attached. This supports you practicing your presentations with the same view you will have during your real speech.

There is also a LaTeX style file available which lets you create a notes file which will be displayed aside the slides.


  • Presenter view with current and next slide view
  • A timer showing the current time and elapsed time
  • Draw on slide during presentation and save the newly created drawing
  • Add notes to the PDF and save the PDF together with the notes in a dedicated format: PDC (Projektor Document Container)
  • Notes editor

Supported Clickers / Presenters

Of course, Projektor supports different types of clickers or presenters. Most of them work naturally, they behave like a keyboard or mouse. A few of them use alternate key codes, which results in a not working gadget. In case this happens let me know and we will see, if I can enable your clicker. Here is a list of clickers I know they work together with Projektor:
  • Satechi Bluetooth Rechargeable Wireless Pointer [ Amazon ]
  • Logitech Wireless Presenter [ Amazon ]

Additional Resources

pdcnotes a LaTeX style file for generating a notes file during a LaTeX run. More about this can be found here.

For your convenience there is a Projektor Document Container creator script, called pdcCreator, written in Python. This creates the PDC structure and copies the PDF and notes file, with the appropriate names, into the structure. More about pdcCreator can be found here.

Frequently Asked Questions

Does Projektor work with any PDF?
Yes! You are not limited to PDF's created with LaTeX.
What is PDC?
PDC stands for Projektor Document Container. It is a special format of Projektor which keeps the PDF and notes file together.
Why is there a special file format?
For your convinience. You can easily copy or move just a single file and cannot forget the notes files.
Do I need to convert all my PDF's into the PDC format?
No! Projektor is fine to work with just PDF's. In fact, if you do not need notes there is no benefit from the PDC format.
How can I create a PDC file?
There are two ways creating a PDC file. Open your desired PDF with Projektor and use the "Save As" menu item. As an alternative, there is a Python script which creates a PDF file out of a PDF and notes file.
Can I create notes even without LaTeX Beamer?
Yes! Projektor is fully capable of creating and editing notes. Just open a PDF and enter your notes. Then use "Save As" to create a PDC file and preserve your notes for later use.
Can I try before I buy?
Yes! There is a special trail version to help you decide whether Projektor does what you need.
I need troubleshooting or have an enhancement request, what to do?
Great, I'm always interested in feedback. In Projektor use the Feedback / Issue reporting item under Help or supply your request here. I try to get back to you as soon as possible.
