What it is for
PDF24 Creator is a free Windows toolbox that merges, splits, compresses, converts and annotates PDFs, plus a virtual printer that turns anything into a PDF. It runs locally, so sensitive documents never leave the machine, which matters for contracts and statements.
When to pick something else
Windows-only, and the interface is a set of separate small tools rather than one polished app. If you only ever merge the occasional file, a single-purpose tool may feel lighter, though PDF24's breadth is hard to beat for free.
How it compares in Documents & Notes
These are the alternatives we would consider for the same job. The notes are the same ones used on the main list, so there is no separate ranking hiding on this page.
| Program | Licence / price | Platforms | Why it is on the list |
|---|---|---|---|
| LibreOffice Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | A complete office suite with no account, no telemetry and no ribbon. Opens and saves .docx and .xlsx reliably enough for everyday work. Install it even if you own Microsoft Office, as a second opinion on stubborn files. |
| ONLYOFFICE Desktop Editors Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | Choose this over LibreOffice if you exchange files with Word users all day: its rendering of .docx formatting is noticeably closer to Microsoft's. Fewer features, better fidelity. |
| Sumatra PDF Publisher's site ↗ | Free · Open source | Windows | Opens PDFs in under a second, remembers where you stopped reading, and has exactly no upsell. It also reads epub, mobi and cbz. There is nothing to configure, which is the whole appeal. |
| Calibre Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | An entire e-book library manager: converts between formats, fixes metadata, and can send books straight to most e-readers over USB or email. Deeply unglamorous, extremely capable. |
| Obsidian Publisher's site ↗ | Free for personal use | Windows, macOS, Linux, Android, iOS | Notes stored as plain Markdown files in a folder you own, linked together into a graph. Nothing is locked in a proprietary database, so you can walk away with everything at any time. |
| Joplin Publisher's site ↗ | Free · Open source | Windows, macOS, Linux, Android, iOS | Markdown notes that sync end-to-end encrypted through a folder, Dropbox or your own Nextcloud, with web clipping and no subscription. Pick it over Obsidian if sync is the priority. |
| Zotero Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | One click in the browser saves a paper, its PDF and its citation data together. Then it formats your bibliography in any style you name. If you write anything with references, this is not optional. |
Practical notes
- Install the PDF printer to 'print' any document to PDF from any app.
- Use the compressor before emailing scans.
- Keep the merge tool for combining statements into one file.

How to read this page. How to read this page. Platform, licence and publisher details come from our directory data. Where an independent review, audit or survey is mentioned, it is summarised in our own words with the source named and linked; our /sources page sets out that policy. The recommendation, the trade-offs and every 'skip it if' line are our editorial judgement. We do not run benchmarks, publish measured performance figures or host installers, and every download link goes to the publisher's own site.
