How to add slide count in Impress

It is useful to indicate the total number of slides in the header or footer of a presentation. This slide count can be added to a presentation created using LibreOffice Impress.

  1. Go to View > Master > Slide master. This displays the master slide, which is used as the template for all slides in your presentation.
  2. Click in the Slide Number Area in the bottom-right corner of the slide and choose Insert > Fields > Page count.
  3. In the Master View dialog hovering over your slide, click Close Master View. You should see the slide count added to all your slides.
  4. You can also add the current slide number in a similar way by choosing Insert > Fields > Page number.

How to add slide number in Impress

LibreOffice Impress is a good tool to create presentations. It is a good habit to have slide numbers in your slides. This helps the audience keep track of progress and also to refer to a particular slide.

To add slide numbers:

  • LibreOffice 4.2.x: Go to Insert > Page Number > Slide

  • LibreOffice 4.4.x: Go to Insert > Header and Footer > Slide

  • Check the Slide number option.

  • The above option adds a slide number on the first slide too. Typically, this is the title slide, where a slide number does not look appropriate. If you feel so, then check the Do not show on first slide option.

  • Remember to click Apply to All. If you click Apply instead, it will apply only to the current slide!

TexMaths is an extension to LibreOffice which enables you to insert LaTeX equations into Writer documents and Impress presentations.


1. You will need LibreOffice and TeXLive, the common LaTeX distribution on Ubuntu. Install them if you don’t have them:

$ sudo apt-get install libreoffice
$ sudo apt-get install texlive

2. Download the TeXMaths extension from its Sourceforge download page. The extension downloads as a .oxt file.

3. Open LibreOffice Writer and go to Tools > Extension Manager > Add and choose the downloaded .oxt file to install it.

4. Close and start LibreOffice Writer again. It typically hangs the first time I install a new extension and its window does not appear. If this happens to you, kill its process. Starting it now should work.


TeXMaths adds a couple of icons to the toolbar in Writer and Impress. To insert a LaTeX equation, just click the equations icon, which is shown as pi. Type the equation you want and click LaTeX. The rendered equation is inserted as an image into the document or slide. To edit it again, select the image and click the equations button again.

How to export animated slides to PDF in LibreOffice Impress

LibreOffice Impress has a useful feature to export the slides of a presentation to PDF. However, if you have animated images in your slides, these animations are not exported to PDF. This is partly because most types of animations cannot be rendered in PDF as pages. However, the most common animation is for images to appear or disappear on mouse click. It should be possible to support these animations in PDF.

The ExpandAnimations extension can be used to export the appear-disappear animations in a LibreOffice Impress presentation to PDF. The download link for the oxt extension file can be found at its Github page. Double-click the file to install the extension using LibreOffice. Once installed, you can export any presentation open in Impress by using Tools > Add-ons > Expand animations
