When you export a presentation from Gamma.app as a PDF, the free tier adds a "Made with Gamma" badge to the bottom-right corner of every page. This watermark includes a clickable link to gamma.app, making it obvious your document was created with a free tool.

If you're sharing a PDF with clients, submitting a research paper, or preparing a professional portfolio, that branding can undermine your work's polish. This guide shows you how to remove the Gamma watermark from PDFs you created and exported yourself — completely free, without uploading your file anywhere.

Quick removal: Use our free PDF watermark remover to clean your file in under 10 seconds. Everything runs locally in your browser.

What the Gamma PDF watermark looks like

The Gamma watermark in PDF exports has a consistent structure:

  • Small clickable image positioned in the bottom-right corner (typically 85-95% from the left edge, 90-95% from the top)
  • Hyperlink annotation that points to gamma.app or gamma.to
  • Appears on every page of the exported PDF
  • Separate from your content — it's layered on top as a distinct object, not embedded in your slides

Because the watermark is a standalone image with a link annotation, it can be removed cleanly without affecting your text, graphics, fonts, or layout.

How the PDF watermark removal works

Unlike image-based watermark removers that blur or crop your content, our tool performs structural removal by editing the PDF's internal format:

  1. Parsing the PDF structure: PDF files store content as a hierarchy of objects — pages, images, text, annotations, links. The tool reads this structure to identify objects that match the Gamma watermark signature.

  2. Identifying the watermark:

    • Scans link annotations (/Annots) for URIs containing gamma.app or gamma.to
    • Tracks image drawing operations (/XObject resources) in the content stream
    • Matches images that overlap with Gamma link positions and fit expected size constraints (small, bottom-right)

  3. Removing the watermark object:

    • Deletes the link annotation from the page's annotation array
    • Removes the corresponding Do (draw image) operator from the page content stream
    • Leaves all other content intact

  4. Writing the cleaned PDF: The tool reconstructs the PDF file without the watermark objects and provides it for download.

This process uses the pypdf library (a pure-Python PDF toolkit) compiled to WebAssembly, so it runs entirely in your browser. Your file never touches a server.

Step-by-step: Remove Gamma watermark from PDF

1. Export your Gamma presentation as PDF

In Gamma.app:

  • Click Export in the top-right
  • Choose PDF as the export format
  • Download the file to your computer

You'll see the "Made with Gamma" badge in the bottom-right corner of each page when you open it.

2. Open the watermark removal tool

Go to gammaremover.com/en/pdf/ — no signup, no installation required.

3. Upload your PDF

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

4. Processing (takes 3-10 seconds)

The tool:

  • Loads the pypdf library into your browser (first time only, then cached)
  • Analyzes each page of your PDF
  • Identifies and removes the Gamma watermark from the PDF structure
  • Generates a clean version

You'll see a progress indicator while it works.

5. Download the cleaned PDF

Once processing completes, click Download to save your watermark-free PDF. Open it to verify — the "Made with Gamma" badge should be gone, and all your original content should remain intact.

Does it work on all Gamma PDF exports?

The tool handles standard Gamma PDF exports reliably. Here are some edge cases:

Works perfectly

  • Single-slide or multi-slide presentations exported as PDF
  • Documents with text, images, charts, and shapes
  • PDFs with embedded fonts and custom formatting

May have limitations

  • Flattened/rasterized pages: If Gamma rendered a page as a single image (rare), the watermark is "baked in" and can't be separated. The tool will notify you if this happens.
  • Password-protected PDFs: If the PDF is encrypted, you'll need to remove the password first.
  • Heavily customized watermarks: If someone manually edited the Gamma export and moved/modified the watermark, detection might miss it.

In rare cases where removal isn't complete, the tool will show a warning: "Watermark may remain on some pages." Always keep your original export as a backup.

Why not just upgrade to Gamma Pro?

Gamma Pro removes the watermark at export time, which is convenient if you create many presentations. However:

  • Gamma Pro costs $15-20/month (as of 2026)
  • If you only need occasional clean exports, post-processing is free
  • You retain full control over your files (no subscription required)
  • The removal process takes less than 10 seconds per file

For individuals, students, or small teams who export infrequently, removing the watermark after export is the more economical choice.

Privacy: Why local processing matters

Many "PDF watermark remover" websites ask you to upload your file to their servers. For presentations containing:

  • Client logos and confidential data
  • Unpublished research or course materials
  • Financial projections or internal memos

...uploading to a third-party server is a serious privacy risk. You don't know:

  • Who has access to your files on their backend
  • Whether files are stored or deleted
  • If your content is used to train AI models

Our tool processes everything locally in your browser. The PDF is:

  • Never uploaded to our servers (or any servers)
  • Never stored in a database
  • Processed entirely in browser memory using WebAssembly
  • Cleared when you close the tab

For sensitive documents, this is the only safe approach.

Technical details: How pypdf works

For those curious about the implementation:

  • The tool uses pypdf (formerly PyPDF2), a pure-Python library for reading and writing PDFs
  • pypdf is compiled to WebAssembly using Pyodide, allowing it to run in the browser
  • The library can parse PDF content streams, identify objects by type, and reconstruct PDFs after modifications
  • Unlike image-processing libraries (PIL, OpenCV), pypdf performs structural edits — no rasterization, no quality loss

The removal script:

  1. Opens the PDF using PdfReader
  2. Iterates through pages, checking /Annots (link annotations)
  3. Filters out annotations with URIs matching gamma.app/gamma.to
  4. Parses the content stream to find small images positioned in the Gamma watermark region
  5. Removes the Do (draw) operator for those images
  6. Writes the modified PDF using PdfWriter

You can view the source code on GitHub if you want to audit the implementation.

Frequently asked questions

Is this legal?
Yes, for files you created and exported yourself. You're removing branding from your own work, not bypassing licensing restrictions or modifying someone else's content. Always comply with Gamma.app's terms of service.

Does it work on scanned PDFs?
No. Scanned PDFs are images, not structured documents. The tool only works on digital PDF exports from Gamma where the watermark is a separate object.

Can I remove watermarks from other tools?
This tool is specifically designed for Gamma watermarks (signature: gamma.app/gamma.to hyperlinks). It won't work on generic watermarks from other platforms.

What if I have 100+ slides?
The tool handles multi-page PDFs efficiently, but browser memory is the limiting factor. Files up to 100MB (~200-300 slides) should process without issues.

Can I use this for commercial presentations?
Yes, as long as the content is yours. The tool removes branding from files you created — it doesn't alter intellectual property ownership or licensing.

Does it work offline?
After the first use (when the pypdf library is cached), the tool can work offline if you save the page. Your file never goes online anyway.

What happens if the watermark isn't fully removed?
The tool will notify you with a "watermark may remain" message. This usually means a page was rasterized. Keep your original export as a fallback.

Is there a batch processing feature?
Not yet. For now, process files one at a time. If you need bulk removal, consider Gamma Pro or contact us for feature requests.

Alternatives to consider

If this tool doesn't meet your needs:

  • Gamma Pro subscription: Removes watermarks at the source, supports team collaboration
  • Manual editing in Adobe Acrobat: Open the PDF, use the "Edit" tool to select and delete the badge (time-consuming)
  • Export to PowerPoint first: Use our PPTX watermark remover, then convert to PDF

For most users, our free PDF tool is the fastest and safest option.
