Slide Converter

The Slide Converter helps you work around one of the main limitations of PowerPoint: converting slides to another slide master?

Without this feature, when you copy paste slides from Presentation A to Presentation B, a lot of things can go wrong and you might have to manually:

  • Change the Layouts of each slide, one-by-one.
  • Remove the master and Layouts created by copy/pasting.
  • Enable/Disable/Reinsert the footers, and adjust their position and formatting (again, one by one!).
  • Make sure that the copied slides use available placeholders instead of text boxes.
  • Adjust colors that depend on the source color scheme and that have been modified when pasting.
  • Resize all shapes manually if page size changes (ex: go from 4/3 to 16/9 slides).
  • Adjust the font in some shapes when lost by the copy paste (due to a bug in PowerPoint).
  • Ensure that UpSlide ToC is working and that all reminders are present and filled.
  • etc...

The Slide Converter, can do all these actions automatically. To use it, select the slides you want to convert and click the Slide Converter button to choose the slide master to which your slides should be converted.

Depending on your use case, you have two options:

  1. If you wish to migrate the slides to another presentation, simply select it from the list. UpSlide will copy the slides and apply the conversion in the destination presentation.
  2. If you simply want to convert your slides to a slide master already present in your presentation, simply click on Repair. This is particularly useful if you receive a presentation that already contains slides that don't comply with your design guidelines.

Once the conversion is over, you can still adjust the result using the options below and clicking Convert Again.



List of actions performed by the slide converter:

Some of these options can be deactivated through the option pane.

  1. Delete footers in the source presentation as they can be completely distorted when copying the slides (only if reset footer is checked).
  2. Unlink colors from the color scheme to preserve them after copy/paste (only if freeze colors is checked).
  3. Copy slides to destination presentation (or to the active presentation in case of a repair).
  4. Apply layout adjustments using correspondence table (see below).
  5. Remove masters and layouts potentially created by copy paste.
  6. Adjust font size to the new page size as PowerPoint can fail to do it automatically.
  7. Adjust shape position and size if page size differs between source and destination presentation, to preserve the slide general aspect (see dedicated paragraph below for additional details).
  8. Convert shape fonts if slide master default font differs between source and destination (only if Convert Fonts is checked). In that case, all fonts that do not exist in the destination presentation are replaced by the destination presentation default font.
  9. Reinsert footers which gives the same result as clicking Insert\Headers & Footers (only if Reset Footer is checked).
  10. Fill empty placeholders with corresponding shape content. A shape matches a placeholder if its area is +/-60% of the placeholder's area, and it overlaps more than 60% of the placeholder (only if Auto-Fill placeholders is checked).
  11. Reposition placeholders converted to shapes when the destination layout contains less placeholders than the source layout.
  12. Adapt Table of Content elements (dividers, reminder, table of content) to the destination presentation table of content format.

In some cases manual adjustments of the formatting may still be necessary. For that, we suggest using the style collection feature.

Layout Adjustments

For each layout in the source master, UpSlide tries to find the corresponding one in the destination master. However, 

When the Slide Converter encounters a new source layout for the first time, it will convert it to the target layout with the closest name (master and layout). In particular, if there is one with the exact same name, it will be pre-selected. 

If, however, the source and destination layouts names differ significantly, you might have to adjust the layout conversion table manually. To do so, simply click on the thumbnail (see picture above) to choose among available layouts in the destination presentation.

Page size change (ex: go from 4/3 to 16/9 slides)

When page size changes between source and destination, PowerPoint default behavior is to resize each shape according to the new slide size while preserving width to height ratio. For example, going from a 4/3 to a 16/9 will apply a 3/4 ratio on all shape heights and will adjust the width in consequence.

This can be desirable, for example when the slide contains images that cannot be distorted, but in general the slides will look emptier and will lose their general aspect.

What UpSlide does is divide the shapes in two categories and apply a different transformation to each.

  • Images and other shapes that cannot be distorted, namely: circles, squares and shape groups. For these shapes, UpSlide keeps PowerPoint default behavior.
  • For all the others shapes, UpSlide will change both the width and the height to match the change in design.

The picture below presents the advantage of using a slide converter to preserve a slide general aspect.




  • The font size is only modified if the page layout is flattened by the migration. In which case, the following formula is applied: new font size = old font size x new page height / old page height.
  • All manual adjustments are saved and will be proposed by default for the next migration.
