Made a deck in Gamma on your phone and need the "Made with Gamma" badge gone before you send it? You don't need a laptop and you don't need to install anything. The removal works directly in your mobile browser — Safari on iPhone, Chrome on Android — because the processing runs on your device, not on a server.

What you need

  • Your Gamma-exported PDF or PPTX file saved on the phone (Files app on iOS, Downloads on Android)
  • Any modern mobile browser
  • One or two minutes

No app install, no account, no upload. The removal engine loads once in the browser tab and processes the file locally via WebAssembly.

Steps on iPhone (Safari)

  1. Export your deck from Gamma as PDF or PPTX and save it — from the share sheet, choose Save to Files
  2. Open GammaRemover in Safari
  3. Tap the upload area — Safari opens the file picker; choose Browse and select your export from Files
  4. Wait a few seconds while the engine loads (first time only) and cleans the file
  5. Tap Download Clean File — Safari saves it back to Files (check the Downloads folder)

That's it. For PDFs you can preview the cleaned pages right in the tool before downloading.

Steps on Android (Chrome)

  1. Save your Gamma export to the phone (it usually lands in Downloads)
  2. Open GammaRemover in Chrome
  3. Tap the upload area and pick the file from Downloads or your file manager
  4. Let the engine process — a few seconds for typical decks
  5. Tap Download Clean File; the cleaned copy appears in Downloads

Phone-specific tips

  • Large files: phones have less browser memory than laptops. Decks under ~100MB are no problem; a 400MB export may be slow or fail on older phones — use a desktop for those.
  • First load takes longest. The removal engine downloads once (then it's cached). On mobile data it may take a little while; on Wi-Fi it's quick.
  • Nothing is uploaded. Processing happens on the phone itself — the file never leaves your device, which is exactly what you want when the deck is a client proposal sitting on your personal phone.
  • PPTX preview: the phone can't render PowerPoint files in the browser, so download the cleaned .pptx and open it in the PowerPoint app or Google Slides to verify.

Why there's no "GammaRemover app"

A native app would add nothing here: the browser version already runs the full removal engine locally, works offline once loaded, and never sends your file anywhere. An app store listing would just be an extra install for the same result. Bookmark gammaremover.com on your home screen instead — on iOS use Share → Add to Home Screen, on Android Chrome menu → Add to Home screen — and it behaves like an app when you need it.

When mobile isn't enough

If the tool reports that the watermark may be flattened into the page image, that limitation is the same on any device — see what to do when the badge can't be removed structurally. And if you're cleaning a whole folder of old exports, a desktop browser handles batches faster simply because selecting many files is easier.

For everything else, your phone is all you need: export, clean, verify, send.
