Apply a template to an existing PowerPoint

You have a finished deck in the old theme, and a company template that marketing actually wants people to use. Applying that template is not the same as changing a font. The template is a slide master, a set of layouts, and a colour theme. The deck is the words and pictures sitting on a different master. This page is the practical version of that job.

What you need

The manual way, so you know what “done” looks like

In PowerPoint you can start from the template and use Home → New Slide → Reuse Slides, then pick the old deck. The slides arrive with their original formatting. You then select them and choose Reset, or pick a layout from the Layout gallery, and fix whatever broke. That works. It is also one slide at a time, and Reset often throws text into the wrong placeholder when the old file never used placeholders.

Copying the master the other direction (Design → browse for a theme) only works cleanly when the source slides were built on standard layouts. A deck made of loose text boxes ignores the new master until someone rebuilds it.

The SlideFit way

  1. Open SlideFit.
  2. Drop the existing deck on the left and the company template on the right. The two sample files are there if you want to see a conversion before you use a real deck.
  3. Choose Fit slides. The preview lists each source slide and the layout it landed on: Title Slide, Section Header, Title and Content, or Picture with Caption.
  4. Download the new .pptx and open it in PowerPoint or LibreOffice. The original files are untouched.

Free conversions keep the first 5 slides and append a watermark slide. $5 unlocks unlimited conversions for 24 hours in this browser, and the timer is not tied to the file bytes. $12 is a one-time 30-day pass. Neither auto-renews. The payment happens on PayPal, and SlideFit stores only the order id in this browser. The pricing section says that plainly.
