PDFRun vs PDF24 Tools
PDF24 is a genuinely free, comprehensive German PDF toolkit — one of the few competitors that, like PDFRun, doesn’t watermark or gate behind accounts. The honest differences are narrower here, and they come down to ads and in-browser privacy.
Last verified: June 2026. Facts about PDF24 Tools come from their own pricing and docs pages — links below.
No ads on tool pages
PDF24’s free web tools are ad-supported — that’s how the free service is funded. PDFRun runs no ads on any tier. If a clean, ad-free tool page matters to you, that’s the main practical difference.
In-browser privacy mode
On 8 tools, PDFRun processes your file entirely in your browser — verifiable in the Network tab, nothing uploaded. PDF24’s online tools process server-side (they offer a separate downloadable desktop Creator for offline use).
Both are genuinely free
Credit where due: PDF24, like PDFRun, has no watermarks and needs no account for its core tools. We won’t pretend otherwise — "free" isn’t our differentiator against PDF24. Ads and browser-mode privacy are.
Workflow tooling
PDFRun adds workflow features (saved workspaces, batch, target-size presets) on Pro. PDF24 is feature-rich but oriented around one-off conversions rather than saved repeatable workflows.

Why we built PDFRun differently
PDF24 is one of the most respected free PDF toolkits on the web, and an honest comparison has to start by acknowledging that: it’s genuinely free, it doesn’t watermark, and it doesn’t force you to create an account for its core tools — the same baseline PDFRun offers. Plenty of comparison pages would invent differences here. We won’t. If your only requirement is "free PDF tools with no watermark and no signup," PDF24 meets it just as PDFRun does.
The real differences are two. First, ads: PDF24’s free online tools are ad-supported, which is how a free service of that scale sustains itself. PDFRun runs no display ads on any tier — funded by Pro subscriptions and credits instead. A PDF24 tool page and a PDFRun tool page are a different experience in that respect, and for some users — especially on work documents — an ad-free page matters.
Second, in-browser privacy. PDF24’s online tools process your file on their servers (they offer a separate free desktop "Creator" for Windows if you want offline processing). PDFRun’s browser-mode runs 8 tools entirely inside your browser tab with no upload at all — verifiable in DevTools. So the privacy options differ in shape: PDF24’s answer is "install the desktop app," PDFRun’s is "stay in the browser, nothing is uploaded." If you’re on Windows and happy to install software, PDF24’s Creator is excellent. If you want zero-install in-browser privacy, PDFRun’s browser-mode fits better.
On breadth, the two are comparable — both have 30–40+ tools covering the common operations. PDFRun leans more toward repeatable workflows (saved workspaces, batch, target-size presets on Pro); PDF24 leans toward fast one-off conversions. Neither is "better" in the abstract — it depends on whether you do the same PDF task repeatedly or different tasks occasionally.
When PDF24 Tools may be the right pick
- You want a completely free toolkit and don’t mind ads on the tool pages.
- You’re on Windows and want a free, full-featured offline desktop app (PDF24 Creator).
- You prefer a long-established German tool with a large existing user base and don’t need saved-workflow features.
- You want native mobile apps rather than a mobile-web experience.
Common questions
Is PDFRun actually different from PDF24, or is this just marketing?
Honestly, the overlap is real: both are free, neither watermarks, neither requires an account for core tools. The genuine differences are (1) PDF24’s free web tools show ads and PDFRun’s don’t, and (2) PDFRun has in-browser processing on 8 tools where the file never uploads, while PDF24 processes online tools server-side (with a separate desktop app for offline). If neither of those matters to you, PDF24 is a perfectly good choice.
Does PDF24 watermark or charge?
No — PDF24’s tools are genuinely free with no watermark. It’s ad-supported rather than paid. That’s a legitimate model. PDFRun’s model is a free tier plus optional Pro, funded by subscriptions rather than ads.
Which is more private, PDF24 or PDFRun?
It depends on the mode. For server-side processing both delete files after processing and don’t inspect content. PDFRun additionally offers browser-mode on 8 tools where the file never leaves your device at all — the strongest option, verifiable in DevTools. PDF24’s equivalent for "never upload" is to install their desktop Creator and work offline. Both are valid; one is zero-install, the other is a local app.
Why would I pay for PDFRun Pro if PDF24 is free?
You wouldn’t, if your needs are one-off conversions — the free tier of either tool covers that. PDFRun Pro is for repeatable workflows: saved workspaces, batch processing, larger files (up to 1 GB), and target-size presets. If you do the same PDF preparation task regularly, those features save real time. For occasional use, stick with either free tier.
