Google Slides is free, runs in the browser, and can open Gamma's PowerPoint exports — which makes it a popular way to strip the "Made with Gamma" badge without paying for Gamma Plus. Here is the full method, including the theme-builder shortcut that removes the badge from every slide at once, and the trade-offs to check before you rely on it.

Step 1: Export from Gamma as PowerPoint

In Gamma, open your deck and choose Share, then Export, then Export to PowerPoint. You'll get a .pptx file. (The PDF export won't work for this method — Google Slides can't edit PDFs.)

Step 2: Import into Google Slides

  1. Go to slides.google.com and create a Blank presentation.
  2. Choose File, then Import slides.
  3. Switch to the Upload tab and select your .pptx file.
  4. Click All to select every slide, and make sure Keep original theme is checked, then click Import slides.

Step 3: Delete the badge — two ways

Per slide (simple, tedious): click the "Made with Gamma" badge in the corner of a slide and press Delete. Repeat on every slide where it appears.

Via the theme builder (all slides at once): in Gamma's exports the badge usually lives on the slide layout rather than the slide itself. Open View, then Theme builder (older UI: Slide, then Edit theme). Look through the layouts on the left for the gamma badge, click it there, and delete it once. Every slide using that layout loses the badge simultaneously. This is the closest Google Slides gets to how the watermark actually works in the file.

Step 4: Re-export

Choose File, then Download, and pick Microsoft PowerPoint (.pptx) or PDF document. Check the corner of a few slides in the downloaded file.

What to watch out for

  • Font substitution. Google Slides only has Google Fonts. Gamma themes that use anything else get swapped, which changes line wrapping and can push text out of its boxes.
  • Transitions and animations from the PPTX are partially or fully dropped on import.
  • Precise layouts drift. Gradients, shadows, and layered images are the usual victims.
  • A Google account is required, and your deck is uploaded to Google Drive — worth knowing if the content is confidential.

About the screenshot workaround

A common suggestion on Reddit is to screenshot each slide and rebuild the deck from images. It works visually, but you lose all text (nothing is selectable or searchable), the resolution is capped at your screen, and file sizes balloon. Treat it as a last resort for one or two slides, not a real method.

The faster option: remove the badge from the file itself

The watermark is a specific gamma.app-linked shape inside the PPTX structure. GammaRemover deletes exactly that shape without converting or re-rendering anything else:

  1. Open the PPTX remover (or the PDF remover if you exported a PDF).
  2. Drop your file in.
  3. Download the cleaned copy.

No import, no font substitution, no account, and the file never leaves your browser. What took ten minutes of slide-by-slide clicking takes a few seconds — and it also handles PDF exports, which Google Slides can't.

Frequently asked questions

Can Google Slides remove the watermark from a Gamma PDF? No. Google Slides can't import PDFs for editing. Either re-export from Gamma as PPTX, or clean the PDF directly with a PDF watermark remover.

Why doesn't the badge appear on my slides in normal view? It sits on the slide layout. Use the theme builder (View, then Theme builder) to see and delete it — or use a tool that edits the file structure directly.

Will my animations survive? Some PowerPoint animations map to Google Slides equivalents, many don't. If animations matter, avoid any import-based method and remove the watermark from the original file.
