Frequently Asked Questions

Everything you need to know about PDF Arranger and secure document management.

Q: Is PDF Arranger really free for commercial use?

Yes, 100%. PDF Arranger is licensed under the GNU GPL-3.0. Unlike “Freemium” tools, there are no locked features, no watermarks, and no subscription prompts. It is free for individuals, students, non-profits, and large-scale commercial enterprises alike.

Q: Is it safer than online PDF tools?

Significantly safer. Most online converters upload your files to a cloud server, creating a potential privacy risk for sensitive data. As a native desktop application, PDF Arranger processes all data locally on your PC. Your documents never leave your machine, making it compliant with strict privacy standards.

Q: Does it support Windows 11 and high-res displays?

Yes. The latest v1.13.0 release is fully optimized for Windows 11 and 10 (64-bit). It supports High DPI scaling, ensuring the interface looks crisp on 4K monitors. We also offer a Portable Version (.zip) for users who cannot install software on work computers.

Q: Can I edit text or convert PDF to Word?

No. PDF Arranger is a page manipulation tool, not a full PDF editor or OCR engine. It excels at merging, splitting, rotating, and cropping. If you need to edit existing text or convert to Word/Excel, you would need a tool like LibreOffice Draw (free) or Adobe Acrobat (paid).

Q: Can PDF Arranger handle very large files?

Absolutely. Because it uses the powerful pikepdf backend, it can handle documents with hundreds or even thousands of pages efficiently. It is designed to be lightweight and doesn’t consume excessive RAM compared to traditional PDF suites.

Q: Why use PDF Arranger instead of Adobe Acrobat?

Adobe Acrobat is a heavy, subscription-based tool with thousands of complex features. PDF Arranger is perfect for users who just need to organize documents quickly. It launches in under 1 second, takes up minimal disk space, and is completely free forever.
