What changes in the file: Only the gamma.app-linked shape on the slide master or layout. Slides, fonts, animations and speaker notes are untouched.
When removal is not possible: If the Gamma watermark was flattened into a slide image instead of staying a shape, there is nothing structural to delete and the tool will say so.

Intended use

This tool is meant for files you created and exported yourself. Removing a credit from someone else's work, or passing off another person's presentation as your own, is not what it is for. Keep the original export as a backup before replacing it.

Where the Gamma watermark hides in a Gamma PPTX — and why removal is lossless

In PowerPoint exports, Gamma places the Made with Gamma badge on the slide master and layout layer, not on your individual slides. That is why you cannot click it in PowerPoint's normal view, and why it appears in exactly the same corner of every slide.

GammaRemover scans the masters and layouts inside the .pptx file and removes only the shapes hyperlinked to gamma.app — the Gamma watermark's unique signature. Content is never matched by text alone, so a slide that happens to say Made with love is completely safe.

Because the file is edited structurally instead of being imported into another editor, everything else survives untouched: fonts, animations, transitions, speaker notes, and embedded media. The whole process runs in your browser with no upload and no account — drop the file, download the clean copy.

Why you cannot click the Gamma watermark in PowerPoint

The Gamma watermark is not on your slide. It lives on the slide layout and slide master, which PowerPoint renders but does not let you select in Normal view. That single fact explains almost every failed attempt to delete it.

Normal view shows it but will not select it

PowerPoint composites three layers when it draws a slide: the master, the layout built on that master, and your slide. You can only click objects on the third layer. The Gamma badge sits on the first two, so it appears in the corner of every slide, survives Ctrl+A, ignores right-click, and cannot be dragged away. People routinely conclude the file is corrupt or locked. It is neither.

It is a shape carrying a gamma.app hyperlink

Structurally the Gamma badge is a shape with a hyperlink whose target resolves to gamma.app or gamma.to. Often it is a Picture shape with no text content at all, which is why searching the deck for the words "Made with Gamma" finds nothing. The hyperlink target, not the wording, is what identifies it unambiguously.

One object on the master, visible on every slide

Unlike the PDF export, where each page carries its own copy, the PPTX badge is placed once per layout or master and inherited by every slide built on it. A deck with several layouts can therefore carry several badge objects even though you only ever see one at a time.

The manual route exists and is tedious

View → Slide Master, find the Gamma watermark on the master and on each layout that shows it, delete each one, then close master view. It works. It also has to be repeated for every layout in every deck, and it is easy to miss a layout that only two slides use — which is why the Gamma watermark reappears halfway through a deck people believed they had cleaned.

What the Gamma watermark remover does to your file

A PPTX is a ZIP archive of XML. The tool opens it with python-pptx inside your browser, finds shapes whose hyperlink resolves to gamma.app, removes those elements from their parent, and repacks the archive. Slides are never re-rendered.

Element removal, not image editing

The Gamma badge shape is detached from its parent element in the presentation XML and the file is written back. Nothing is rasterised, re-encoded, or re-laid-out. Your fonts, animations, transitions, speaker notes, embedded media and slide dimensions come through byte-for-byte identical, because none of those parts of the archive are touched.

It searches the layers you cannot reach

Because the tool works on the archive rather than through the PowerPoint UI, it inspects slides, layouts and masters in one pass. There is no equivalent of forgetting to check a layout — every part of the package that can hold a gamma.app-linked shape is examined.

The corner position is a hint, never the trigger

A shape sitting past 70% of the slide width and height is treated as corner territory, which raises confidence. On its own it proves nothing — plenty of legitimate design elements live in the bottom-right. Removal requires the gamma.app or gamma.to hyperlink target. Matching the bare phrase "Made with" is explicitly forbidden, because a genuine slide reading "Made with love by our team" would otherwise vanish.

The result stays editable

The output is a normal .pptx that opens in PowerPoint, Keynote, Google Slides or LibreOffice with every element still editable. This is the practical difference from exporting to PDF or to images to escape the Gamma watermark: you keep a working source file rather than a flat picture of one.

When people need to remove the Gamma watermark from PPT

PPTX cleaning matters when the deck still has to be edited or presented, not just delivered. Anyone who needs to keep working on the file cannot solve the Gamma badge by flattening it to images.

Decks that get handed to a colleague

Internal presentations get passed around and edited by several people. A badge on the master reappears on every new slide anyone adds, so the problem grows with the deck rather than staying fixed at export time.

Template reuse

Teams that build a deck once and reuse the layouts for a year inherit the Gamma badge into every future presentation. Cleaning the master once removes it from everything built on that template afterwards.

Live presenting from PowerPoint

Presenter view, rehearsal timings and embedded video all need the real PPTX. Converting the deck to images to hide a badge costs all three.

Client-facing and graded work

The same logic as PDF: a tool badge on a deliverable advertises the tool and reads as unfinished to anyone who does not know what Gamma is.

Gamma watermark limits and honest failure modes

Files above 500 MB are rejected. If a badge was flattened into a slide background image before you got the file, there is no shape left to remove, and the tool says so rather than returning an unchanged deck silently.

Flattened badges cannot be removed structurally

If the deck has been through a conversion that turns slides into pictures — some PDF-to-PPTX converters do exactly this — the Gamma watermark becomes part of a slide image. At that point there is no shape to detach, and honest removal would require pixel editing. The engine flags that the Gamma watermark may remain instead of claiming success.

500 MB ceiling, and the one-time engine load

Processing runs in browser memory, so 500 MB is the practical limit. The first file you drop also downloads the Python runtime and its libraries — tens of megabytes, once, then cached. Both the PDF and PPTX engines share that initialisation, so cleaning a PDF first makes the first PPTX instant.

Gamma only

Detection is bound to gamma.app and gamma.to link targets. Canva, Tome, Pitch, Beautiful.ai and Visme badges are different objects with different fingerprints and are not removed here.

A deck can legitimately contain zero badges

Exports from paid Gamma plans have no badge at all. If the tool reports nothing found, the most likely explanation is that there was nothing to find.

Troubleshooting Gamma watermark removal in PowerPoint

Three symptoms cover nearly everything: the Gamma badge survives processing, the Gamma badge returns on new slides, or PowerPoint refuses to open the result. Each has a specific cause.

The badge is still there after processing

Test whether it is still a real object: open Slide Master view and try to select it. If it can be selected there, the shape exists and the file you processed was probably not the file you re-opened — check your downloads folder for a second copy. If it cannot be selected anywhere, it has been flattened into a background picture and needs a fresh export from Gamma.

It comes back when someone adds a slide

That slide was built on a layout whose badge was never removed. Decks routinely carry five or six layouts and only two or three are visibly in use. Cleaning through the archive covers all of them at once; cleaning by hand in Slide Master view usually does not.

PowerPoint reports the file is damaged

Almost always this means the file was already partially damaged, or it was renamed to .pptx without actually being one — a PDF or Keynote file with the extension changed will fail here. Re-export from Gamma and try the fresh file.

You need PDF instead

A PDF export stores its badge completely differently: a corner image plus a link annotation on every page, not a shape on a master. Use the PDF tool for those files.

Privacy, cost, and the licence question behind the Gamma watermark

Your deck is processed inside your own browser with no upload, no account and no usage cap. Whether removing the Gamma watermark is permitted for your plan and purpose is a question about your agreement with Gamma.

The file never leaves the tab

There is no server that receives the .pptx. The Python runtime executes locally in WebAssembly, which is why the tool keeps working offline once the engine is cached. Confidential board decks and unreleased product material never transit a third-party machine.

Free without a metering scheme

No sign-up, no credits, no per-file limit — there is no server-side cost per file to recover, because your own CPU does the work.

What this tool does and does not decide

The tool performs a technical edit on a file you already have. It does not grant you a licence. Gamma's terms govern free-tier output and those terms change over time. If the deck is commercial and the position is unclear, a paid Gamma plan resolves both the licence question and the Gamma badge in one step.

Gamma PPTX watermark remover FAQ

How do I remove the Made with Gamma watermark in PPT?

Drop the .pptx exported from Gamma and download the cleaned deck. The Gamma watermark is one shape carrying a gamma.app hyperlink; we detach it from the slide layout and master, and every slide is clear in the same pass.

Why does the Gamma watermark appear on every slide?

Because it is not on the slides at all. Gamma places the Gamma watermark on the slide layout and master, the templates every slide inherits from, so one shape renders on all of them. Delete it in one place and it disappears everywhere.

I deleted it in PowerPoint and it came back — why?

You deleted it on a slide, but the shape lives on the master. PowerPoint redraws it from the master on the next render. Editing masters by hand means View, Slide Master, then hunting the shape across every layout — this tool does that pass for you.

Do I need PowerPoint installed?

No. The .pptx is unzipped, edited and re-zipped inside your browser by python-pptx compiled to WebAssembly. Any device with a modern browser works, including a phone.

Will animations, fonts and speaker notes survive?

Yes. Only the Gamma watermark shape's XML node is removed; every other part of the package — transitions, notes, embedded video, custom fonts, theme colours — is repacked untouched.

Can I open the cleaned deck in Google Slides or Keynote?

Yes, the output is a standard .pptx. Clean it here first, then import — importing a badged deck into Slides converts the Gamma watermark into a native shape and it stops being a single removable object.

Is the PowerPoint file uploaded anywhere?

No. Processing happens in a Web Worker in your tab; the file is never sent to a server and nothing about it is logged.

Why is the badge still there after cleaning?

If your export baked the Gamma watermark into a slide background image rather than keeping it as a shape, no shape exists to remove. The tool reports that instead of returning a silent no-op. Re-exporting from Gamma as .pptx usually restores a removable shape.
