What PDF24 Tools is

PDF24 is a long-running German PDF project with two faces. The online tools run in the browser with no installation: convert between PDF and Word, Excel, PowerPoint or images, merge, split, rotate, compress, add page numbers or watermarks, fill and flatten forms, extract text and images, and run OCR on scanned pages. PDF24 Creator is a free Windows application that bundles the same toolset with a virtual PDF printer and works offline, so files never leave the machine. The site says transfers to its online servers are encrypted and that files are removed shortly afterwards, and that there are no artificial limits on what you can do. It is funded by advertising on the web pages rather than by subscriptions, which is why there is no paid tier to compare. The interface is plain, the English is occasionally stiff, and the desktop app is Windows only, but the coverage is broader than most paid suites.

Best for

Converting and combining PDFs without buying a subscription
Keeping sensitive documents local through the desktop Creator app
One familiar toolbox that covers the long tail: OCR, flattening, page numbers

Not ideal for

Scripted pipelines, since there is no documented API
Client-facing work where an ad-free interface matters

Pros

Genuinely free: no caps, no watermarks, no trial clock
The offline Creator keeps documents off the network entirely
Covers the obscure jobs: flattening, page numbering, text extraction, OCR

Cons

Advertising sits on every online tool page
The desktop Creator is Windows only; Mac and Linux users get the web version
Interface is utilitarian, and translations read unevenly

Pricing in detail

Free in both forms. The online tools are funded by advertising on the page, and the site states there are no artificial limits, no watermarks and no daily caps. PDF24 Creator is a free download for Windows, for private and business use, running the same tools offline with nothing sent anywhere. There is no paid edition, no seat count and no upsell to a pro plan, which is unusual for a PDF suite and is the main reason its coverage can be trusted.
