Gamma.app makes it easy to create presentations and export them as PowerPoint (.pptx) files. But if you're using the free tier, every slide will include a "Made with Gamma" badge — usually in the bottom-right corner with a hyperlink to gamma.app.

Whether you're presenting to stakeholders, submitting coursework, or sharing templates with your team, that branding can look unprofessional. This guide shows you how to remove the Gamma watermark from PowerPoint files you created and exported yourself — completely free, without uploading your presentation to any server.

Quick removal: Use our free PPTX watermark remover to clean your file in seconds. Everything processes locally in your browser.

What the Gamma watermark looks like in PPTX files

The Gamma watermark in PowerPoint exports appears as:

  • A shape or grouped object (often combining an image and text) with a clickable hyperlink to gamma.app or gamma.to
  • Located on the slide master or layout, which is why it propagates to every slide automatically
  • Positioned in the bottom-right corner (typically 85-95% from the left edge)
  • Separate from your slide content — it's an independent shape layered on top, not part of your text boxes, images, or charts

Because the watermark is stored as a distinct shape with a recognizable hyperlink, it can be identified and removed cleanly without affecting your slides' content, animations, or transitions.

How PowerPoint watermark removal works

Unlike tools that screenshot your slides or overwrite the watermark with a white box, our approach performs structural editing of the .pptx file format:

Understanding .pptx structure

A PowerPoint file isn't a single binary blob — it's actually a ZIP archive containing:

  • ppt/slides/ — XML files for each slide
  • ppt/slideMasters/ — Master slide templates
  • ppt/slideLayouts/ — Layout templates that reference masters
  • ppt/media/ — Embedded images and media
  • Various XML files describing relationships, themes, and properties

The Gamma watermark is typically stored as a shape in the slide master (e.g., slideMaster1.xml) or in specific layouts. Because masters and layouts are inherited by regular slides, removing the watermark from the master automatically removes it from all slides.

The removal process

  1. Unzip the .pptx file to access the internal XML structure
  2. Scan slide masters and layouts for shapes with hyperlinks (<a:hlinkClick>) pointing to gamma.app or gamma.to
  3. Remove matching shapes by deleting their parent XML elements (<p:sp> or <p:grpSp>)
  4. Also scan individual slides as a fallback, in case the watermark was placed directly on slides
  5. Rebuild the .pptx file by re-zipping the modified XML files

This entire process uses the python-pptx library (compiled to WebAssembly via Pyodide), running entirely in your browser. No server-side processing, no upload.

Step-by-step: Remove Gamma watermark from PPTX

1. Export your Gamma presentation as PowerPoint

In Gamma.app:

  • Click Export in the top menu
  • Select PowerPoint (.pptx)
  • Download the file

Open it in PowerPoint, Google Slides, or Keynote — you'll see the "Made with Gamma" badge on every slide.

2. Go to the watermark removal tool

Visit gammaremover.com/en/pptx/ — no account or software installation needed.

3. Upload your PPTX file

Drag your PowerPoint file into the upload zone, or click "Select file" to browse. The tool supports files up to 100MB.

4. Processing (5-15 seconds)

The tool:

  • Loads the python-pptx library into your browser (first upload only, then cached)
  • Extracts the .pptx ZIP contents
  • Scans slide masters, layouts, and individual slides for shapes with gamma.app hyperlinks
  • Removes matching shapes from the XML structure
  • Reconstructs the .pptx file

You'll see a progress indicator while it works.

5. Download the cleaned PPTX

Click Download to save your watermark-free PowerPoint file. Open it in your presentation software — the "Made with Gamma" badge should be gone, and all your slides, animations, transitions, and formatting should remain intact.

Does it preserve animations and formatting?

Yes. Because the tool removes only the watermark shape from the XML structure, everything else in your presentation is untouched:

✅ Preserved:

  • Slide layouts and themes
  • Text formatting, fonts, and styles
  • Images, charts, and SmartArt graphics
  • Animations and slide transitions
  • Embedded videos and audio
  • Speaker notes
  • Custom color schemes

The tool doesn't re-render your slides or convert them to images — it performs a surgical edit of the underlying XML, leaving your presentation fully editable.

What if the watermark doesn't disappear?

The tool handles standard Gamma PowerPoint exports reliably. Edge cases:

Works perfectly on:

  • Multi-slide presentations with master/layout watermarks
  • Presentations with complex animations and embedded media
  • Files exported from Gamma.app's free tier (2024-2026 formats)

May have limitations:

  • Custom watermark placements: If someone manually moved the Gamma badge to an unusual location or removed its hyperlink after export, detection may miss it.
  • Flattened images: If a slide was rendered as a single image with the watermark embedded, it can't be separated. Rare but possible.
  • Password-protected files: The tool can't process encrypted .pptx files. Remove the password first.

If the tool can't fully remove the watermark, it will show a warning. Always keep a backup of your original export.

Gamma Pro vs. post-processing

Gamma Pro (paid subscription) removes the watermark at export time, which is convenient for frequent users. However:

  • Gamma Pro costs $15-20/month (as of 2026)
  • Post-processing is free and takes under 15 seconds per file
  • You don't need an ongoing subscription for occasional clean exports
  • The tool works on files you exported weeks or months ago

For students, freelancers, or teams who export infrequently, removing the watermark after export is the more economical approach.

Why local processing protects your privacy

Many "PPTX watermark remover" tools require you to upload your presentation to their servers. For decks containing:

  • Confidential client proposals
  • Unreleased product roadmaps
  • Academic research or exam materials
  • Personal or organizational data

...uploading to a third-party server is a privacy and security risk. You have no control over:

  • Who accesses your files on their backend
  • How long files are stored (even "deleted" files may remain in backups)
  • Whether your content is used for AI training or other purposes

GammaRemover processes everything in your browser. The removal engine (python-pptx library compiled to WebAssembly) runs as a Web Worker on your local machine. Your file:

  • Is never uploaded to a server
  • Never passes through a network (except when you download the cleaned result)
  • Is cleared from browser memory when you close the tab

For business and academic users, this is the only truly safe approach.

Common questions

Can I use this on presentations I didn't create?

This tool is designed for removing watermarks from files you created and exported yourself. Using it on presentations created by others may violate their rights or Gamma.app's terms of service. Always respect intellectual property and licensing agreements.

Will this work in Google Slides or Keynote?

Yes. The cleaned .pptx file is a standard PowerPoint format that opens in:

  • Microsoft PowerPoint (Windows, Mac, Web)
  • Google Slides (upload the .pptx to Google Drive)
  • Apple Keynote (import the .pptx)
  • LibreOffice Impress
  • Any software that supports the PPTX format

All formatting, animations, and content remain compatible.

Can I process multiple files at once?

Currently, the tool processes one file at a time to ensure browser performance and reliability. If you have many presentations to clean, process them sequentially — each file takes 5-15 seconds.

Does the tool modify embedded images or videos?

No. The tool only removes the Gamma watermark shape. All embedded media (images, videos, audio, charts) remains untouched and fully functional.

What if my presentation has a custom Gamma logo I added manually?

The tool identifies watermarks by their hyperlink (gamma.app/gamma.to) and typical positioning. If you manually added a Gamma logo as a regular image without that hyperlink, the tool won't remove it — it only targets the auto-added export watermark.

Is this legal?

Removing a watermark from a presentation you created and exported yourself is generally legal, as you own the content. However, you should:

  • Review Gamma.app's terms of service
  • Respect any licensing restrictions on templates or media you used
  • Avoid claiming third-party content as your own

This tool does not bypass Gamma Pro's features or violate any digital rights management (DRM) — it simply removes branding from content you created.

Can I use the cleaned file commercially?

Your rights to use the presentation (commercially or otherwise) depend on:

  • Gamma.app's terms for content you create on their platform
  • Licensing of any templates, images, or media you included
  • Your organization's intellectual property policies

Removing the watermark doesn't change these underlying rights. Always verify you have permission to use the content as intended.

What if processing fails?

If the tool encounters an error:

  1. Make sure your file is a valid .pptx export from Gamma.app
  2. Check that the file isn't password-protected or corrupted
  3. Try re-exporting from Gamma and processing again
  4. Keep the original file — you haven't lost anything

The tool is tested on thousands of Gamma exports, but occasional format variations can occur. If you encounter a persistent issue, it may indicate an unusual export format.
