Something went wrong.

Your deck never touches a server.

Nothing is uploaded

The cleanup runs in your browser tab. Go offline after the page loads and it still works.

Open source

Every line is on GitHub. Read it, audit it, fork it.

Free, no account

No limits, no email wall, no watermark of our own.

Three steps, about ten seconds.

  1. Export from Gamma

    Open your deck in Gamma and export it as a PowerPoint (.pptx) file.

  2. Drop it on the slide

    Ungamma finds the repeated badge images in your slides, layouts, and masters.

  3. Download the clean copy

    Your original stays untouched. Open the new file and check it before presenting.

Questions people ask.

How do I remove the Gamma watermark from a PowerPoint?

Export your deck from Gamma as PPTX, drop it into the slide above, and download the cleaned file.

Is it safe? Do you upload my presentation?

No. The file is processed entirely in your browser and is never sent anywhere.

Will it break my slide design?

It skips full-slide background images and only removes repeated badge assets. Your original file is never modified, and you should still check the result.

It didn't remove the badge. Why?

This tool is built only for the "Made with Gamma" watermark in Gamma PPTX exports. If it missed one, open an issue on GitHub and we'll look at it.

Saved your deck? Give it a star.

It takes one second, it's free, and it's the only way this tool gets found by the next person fighting a watermark.
