Best free PDF merger and splitter for Windows (2026)
Every tool on this list runs locally on your Windows PC — none of them require uploading your documents, which rules out the web apps that dominate search results. There is no single winner: the right pick depends on whether you want a broad suite, a command-line-friendly open-source tool, or a focused merge-and-split app.

1. PDF Merge & Split Pro — best for focused, private merge and split
Best if you want one thing done well: combining PDFs and pulling them apart, on Windows, with nothing uploaded and no account. It is the only tool here that combines offline processing with password-protected output and PDF metadata editing.
- Merge in any order; merge only selected pages from each file
- Split into single pages, groups, equal parts, page ranges, or by bookmark level
- Built-in preview — no Adobe Reader needed
- Open password-protected PDFs; set open passwords and permissions on output
- 15+ interface languages; portable ZIP version for USB sticks
- Under 10 MB, no adware or spyware
Trade-off: the free edition caps merges at 3 files and splits at 20 pages. It also does not convert, compress, OCR or edit text — it is deliberately narrow.
2. PDF24 Creator — best for a broad free suite
Best if you want one free installer that covers merging, splitting, conversion, a virtual PDF printer and more. For a completely free tool, the breadth is unusual.
Trade-off: it is a large suite for what may be a small job, and the installer historically offers optional third-party components — take the time to read each screen. The interface feels utilitarian compared with a focused app.
3. PDFsam Basic — best for power users and scripted workflows
Best if you split large documents regularly — by bookmark, by size, or into fixed page counts — and want something scriptable and cross-platform. It is open source, so you can audit it.
Trade-off: it runs on Java, which adds overhead and makes the installer heavier than the rest. Some advanced modules sit behind a paid tier.
4. PDF Arranger — best for quick page reordering
Best if your real task is visual: drag pages around, delete a few, merge a handful of files by dropping them in. It is small, open source and uncomplicated.
Trade-off: fewer output controls — no password setting, no metadata editing, and splitting is by selection rather than by rules.
Short version: need everything in one free suite → PDF24 Creator. Automating splits of structured documents → PDFsam Basic. Just reordering pages → PDF Arranger. Merge and split done properly, offline, with password and metadata control → PDF Merge & Split Pro.
