Reusing slides across presentations without losing fonts, layouts and charts

What really happens when you copy a slide

A slide does not carry its own fonts and colours: it inherits them from the layout, which in turn inherits them from the file’s master. Pasted into another file, PowerPoint attaches it to the closest layout it finds there. If the theme is different, fonts, theme colours, placeholders and sometimes sizes change.

The "Keep source formatting" option helps, but it brings along one extra master per copy. After twenty copies the file has twenty masters and weighs three times as much.

The method that holds: compose, do not copy

The clean way is to reverse the order. Instead of opening an old deck and copying from there, you start from the slides: pick them in a library, put them in order, and generate the new file carrying each slide’s original master, once.

With Slide Atlas composition is a drag: you search for the slides, drag them into the new deck at the right spot, and the native export produces a .pptx with the original, editable slides and their masters. Slides that share a master share it in the exported file too.

When the presentation is already open

The most frequent case is not "create a new deck": it is "I am working on a presentation and I need that slide". That is what Send to PowerPoint is for. A small connector installed on Windows recognises the presentations open on your PC: pick the slide in Slide Atlas and it enters the open PowerPoint, where your cursor is, with its original master, layout and fonts. No export, no file to reopen.

Three rules for slides that reuse well

• One slide, one message. Slides that do three things never get reused, because two of the three are not needed.
• Use the layout placeholders, not free text boxes: they are what stays in place when the slide changes home.
• Keep charts as PowerPoint charts, with the data inside. A chart pasted as an image cannot be updated and cannot be searched.
