PDF24 and PDF Arranger are both free ways to organize PDF pages on a Windows PC, but they are built on different philosophies. PDF24 is a broad toolbox: a free Windows desktop program (PDF24 Creator) plus an online tool suite (PDF24 Tools) covering everything from merging to compression and conversion. PDF Arranger is a specialist: an open-source desktop app that does page arranging — and only page arranging — in one visual window. Here is how to pick between a toolbox and a specialist.
At a glance
| PDF Arranger 1.14.0 | PDF24 | |
|---|---|---|
| Price | Free, open source (GPL-3.0-or-later) | Free desktop Creator and free online Tools |
| Source code | Open source | Closed source |
| Platforms | Windows and Linux; macOS only via Nix | Windows desktop app, plus web-based tools |
| Page organizing | Core strength: visual drag-and-drop merge, split, reorder, rotate, crop | Included in the toolbox |
| Booklet | Yes — generate and split booklet layouts | Not officially documented |
| Compress and convert | No compression and no format conversion | Yes — compression and conversion are part of the toolbox positioning |
| Edit text and OCR | No | Editing tools are part of the toolbox; per-tool details are not officially documented in the sources checked for this article |
| Where files are processed | Locally on your computer, fully offline | Locally in the desktop app; uploaded when you use the online tools |
Toolbox vs. specialist
PDF24’s appeal is coverage. If your PDF chores vary — merge these pages today, shrink a file for email tomorrow, convert something next week — one free installation with a tool for each job is convenient, and the online tools are there when you are on a machine without the desktop program. That breadth is real, and for a Windows-only user who wants everything in one place, it is a sensible default.
PDF Arranger deliberately covers less. It cannot compress or convert at all. What it offers instead is depth at one job: every page of every open document visible at once, drag-and-drop reordering, white-border and margin cropping, page-size changes, booklet generation, metadata editing, image import, and password-protected export, all in a single window with nothing to configure. People who organize PDFs every day usually feel the difference within one document.
Open source and platforms: the decisive split
Two facts decide this comparison for many readers. First, licensing: PDF Arranger is open source under GPL-3.0-or-later, so its code can be inspected and it is packaged by Linux distributions and Flathub. PDF24 is closed source — you use it on its maker’s terms. Second, platforms: PDF24’s desktop app is Windows-only, with its web tools as the fallback elsewhere. PDF Arranger runs natively on Windows and Linux. If you work across both systems, or you simply prefer auditable open-source software, the specialist wins on principle before features are even discussed.
Privacy follows the same line. PDF Arranger processes everything locally and works fully offline. PDF24’s desktop app also works locally; its online tools, by design, involve uploading your file to a service — fine for a public document, a real consideration for contracts, IDs or anything personal.
One transparency note: this comparison deliberately does not quote a PDF24 version number. The current Creator version and the exact free-versus-paid boundary of each tool were not officially documented in the sources checked for this article, so we would rather leave the cell honest than fill it with a number copied from a third-party download site.
Verdict: who should choose which
- Choose PDF24 if you are Windows-only and want one free toolbox that also compresses and converts, and you are comfortable with closed-source software.
- Choose PDF Arranger if you value open source, need Linux support, or organize pages often enough that a focused visual arranger beats a general toolbox.
- Need professional-grade editing or OCR on top? That is beyond both free tools’ core promise; a full editor such as Adobe Acrobat (sponsored) or Wondershare PDFelement (sponsored) is the honest step up.
