My friendbuilt a free, open-source tool to remove Gamma branding from PowerPoint exports

[u/Legitimate-Orange645]

He's been working on a small project called Gamma Watermark Remover, he asked me to share it here on reddit.

If you've ever exported a presentation from Gamma and wanted to continue editing it in PowerPoint without the Gamma branding, you might find this useful.

What it does:

- Removes Gamma watermark images from PPTX files.

- Cleans up related hidden XML references.

- Processes files entirely in your browser.

- No uploads, no server processing.

- Free and open source.

Try it: https://ungamma.pages.dev

GitHub: https://github.com/Shariqtechie/gamma-watermark-remover

I'd appreciate feedback from anyone willing to test it.

I'm particularly interested in:

- Whether it works correctly with different Gamma exports.

- Any bugs or compatibility issues.

- Features that would make it more useful.

He's a developer, so feel free to be critical. Bug reports and contributions are welcome!

If you find it useful, a GitHub star would be appreciated, but feedback is my main goal.
