Documents in. Nothing uploaded.

What happens when you add files?

Your browser gives Gluecut temporary access to the files you select. Gluecut reads those bytes locally and builds previews suitable for arranging the document. It does not upload the file contents to a Gluecut backend because there is no document-processing backend.

What output should you expect?

When every source file uses the same supported format, Gluecut keeps that format where the browser-based merger supports it. A mixed-format assembly is converted into a PDF so the different document types can share one output.

Word and PowerPoint previews are approximate because a browser does not include Microsoft Office's full layout engine. Always inspect the downloaded result before using it as a final business or legal document.

Is Gluecut completely offline?

The document-processing functionality runs locally. Some site resources and the About page's advertising service require an internet connection. Advertising code does not receive your selected document contents.

How to merge documents privately

1. Open Gluecut in a modern browser.
2. Select or drop the files you want to combine.
3. Drag the generated pages or sections into the desired reading order.
4. Remove unnecessary units and review approximate previews.
5. Choose Merge & Download. The generated file is downloaded by your browser.

Limits and safety

Large files consume device memory, so practical limits depend on the browser and device. Password-protected or damaged files may not be readable. Gluecut is a convenience tool, not an archival, compliance, or digital-signature service.
