PDF24 Alternative for Anyone Without a Windows PC

The download page said it straight: "files remain locally on your PC and are not uploaded to the Internet." You believed it, because it was true. Then you clicked the same link on the Chromebook your kid does homework on, or a work laptop your IT department has locked down, and what landed in Downloads was pdf24-creator-installer.exe. Nothing about that runs on ChromeOS, and nothing about it runs without admin rights you don't have. The choice narrowed to one option: open the browser tool instead — the PDF24 alternative that isn't one — and hand it the exact file you'd gone looking for a local tool to avoid handing anyone.

That's the whole story with PDF24. Not a task quota, not a watermark. A privacy promise that only ships for one operating system.

What PDF24 actually is

PDF24 is a PDF toolkit built by Geek Software GmbH, a small Berlin-based team that's been at this since 2006, back when the project carried the older name PDFDrucker. There's no watermark stamped on exports and no page or file-count ceiling to bump into, the two things that trip up nearly every other tool in this category. Two decades in, it's still run by, in the company's own words, "a small agile team" rather than a venture-scaled operation. Geek Software GmbH is registered at Friedrichstraße 171 in Berlin, per its own privacy policy — a real, checkable address behind the brand, which is more than plenty of "free PDF tool" sites bother to publish.

What PDF24 Creator can actually do

Strip away the platform argument for a second, and Creator is a genuinely deep piece of software. It installs as a virtual PDF printer, so any Windows program that can print — a word processor, an accounting package, a browser — can print straight to a PDF instead of paper, with no separate conversion step. PDF24's own feature page lists "multiple PDF printers for different tasks," alongside scanner and camera import for pulling paper documents straight into a PDF and automatic-saving rules for where finished files land. It ships in 39 languages, and beyond the ordinary EXE installer, PDF24 offers an MSI build explicitly meant "for distribution on corporate computers," the kind of detail that matters to an IT department pushing software to a hundred machines at once — if that fleet happens to run Windows.

All of it, the printer, the languages, the corporate rollout, is locked to the one platform Creator runs on. PDF24 says so itself: Windows 10 and 11, nothing else.

Two products wearing one name

Here's the part the marketing blurs together. "PDF24" is two separate products with opposite privacy models, and the name alone doesn't tell you which one you're using. In one sentence: PDF24 Creator is the offline Windows app that never touches a server, and PDF24's web tools are the browser-based service that uploads every file it processes.

PDF24 Creator is the desktop app: "a desktop solution that works offline. Files remain locally on your PC and are not uploaded to the Internet." That's real local processing, the thing people actually mean when they ask for a privacy-first PDF tool.

tools.pdf24.org is the other half, the web tools you land on the moment Creator isn't installed, can't be installed, or you just clicked a search result. Every one of those tools uploads your file to a PDF24 server before it does anything. That's not hidden. It's just never in the same sentence as "files stay local," because that sentence is only true for one of the two products sharing the brand.

PDF24's phone "app" is the same upload, wearing an icon

There's a third option that looks like it might close the gap, and it's worth naming precisely because of how easy it is to misread. PDF24's own tools page tells you: "You can also install PDF24 as an app on your smartphone. To do so, open the PDF24 Tools in Chrome on your smartphone." That's a Progressive Web App, an icon on your home screen that opens tools.pdf24.org in its own window with the browser chrome stripped away, not a native app pulled from the App Store or Play Store. Nothing about the underlying processing changes: tap the icon, pick a tool, and the file you choose still travels to the same server the ordinary mobile browser version uses. The icon changes how it looks on your screen. It doesn't change where your file goes.

That's an easy detail to miss, because "install as an app" reads like the local-processing promise Creator makes on Windows. It isn't the same promise. If your phone is the device doing the work, you're on the upload path no matter which button you tapped to get there.

Free, and not the usual catch

No premium tier for end users, no trial countdown, nothing behind a paywall. PDF24's own tools page says it directly: "You can use all PDF24 tools free of charge and without any restrictions... There are no artificial limits at PDF24." The FAQ explains what funds that: the tools are "financed by means of discreet advertising on the websites," not by squeezing free users toward a paid plan.

Set that against Sejda's three-tasks-per-hour wall or PDFelement's watermarked trial, and PDF24 looks almost old-fashioned in its generosity. If none of the caveats below apply to you, it's a good deal, plain and simple.

That ad-supported model has a footnote worth knowing before you upload something sensitive. PDF24's own privacy policy discloses Google AdSense, Google AdWords, and an anonymized Google Analytics integration running on the same pages your file passes through, with a cookie-consent gate for anything not strictly necessary to run the site. None of that is unusual for an ad-funded tool, and PDF24 discloses it plainly rather than burying it in a EULA. It's a different question from where the file itself goes, but it's part of the same page load, and worth knowing if "free" is doing a lot of the work in your decision.

The one-hour clock: how long PDF24 keeps your file

To PDF24's credit, they say exactly what happens next instead of staying vague about it. Per the FAQ: "uploaded files in the online tools are automatically deleted from the server after one hour." The privacy policy adds the detail that matters most: "During this hour we do not look at the files and do not evaluate them. Backups of these files are generally not created." Servers sit inside the EU.

An hour is a short window, and a written commitment not to look at or back up your file is more than most competitors bother to put in writing. It's still an hour where your tax return or your kid's report card sits on hardware that isn't yours. If your own device could have done the job, that hour was never necessary in the first place.

That same policy adds two more details that read as reassuring. The upload and the download are both "protected by SSL" in transit, and file access inside the company is restricted to "authorized employees or employees of third-party companies (e.g. service providers)" rather than open to the whole team. That's a normal, competent way to run a file-upload service. It's also still a claim you're taking on trust, the same way you'd take PDF24's word for the one-hour deletion itself. A local tool doesn't ask you to trust anyone's access policy, because there's no second party's server anywhere in the sentence.

Windows or nothing: PDF24 on Mac and Chromebook

Go looking for a Mac or Linux build of PDF24 Creator and PDF24 answers the question itself, on its own download page: "No, the PDF24 Creator can only be installed on Windows systems. Linux and MAC are not currently supported." Not "not yet, on the roadmap." Not yet, full stop, after nearly twenty years of active development.

That one line decides which privacy model you get. Windows machine, admin rights: install Creator, process files locally, never touch a server. Mac, Chromebook, Linux box, tablet, phone, or a work laptop where you can't install anything at all: you're on the web tools, uploading, every single time.

Want to see the difference instead of reading about it? Install Creator on a Windows machine, merge two files, and watch your network activity while it runs. Nothing goes out, because nothing needs to; the FAQ's "local" claim holds up under a check. Now open one of the .org web tools on any device and repeat the exercise: watch DevTools' Network panel while you click convert, and you'll see a request leave for a tools.pdf24.org endpoint the moment you do — exactly what the FAQ already told you happens. Your file uploads, gets processed, and downloads back over an SSL connection sometime in the next hour. Neither behavior is a secret. Seeing it happen is just a different kind of confirmation than reading a sentence about it.

What independent reviewers say about PDF24

PDF24 carries a 4.5-star Trustpilot rating across 114 reviews on its main tools domain, as of September 2026. Solid, if a modest sample next to a giant like Sejda or iLovePDF. The praise matches the facts above: people like that it costs nothing and gets the job done. The complaints are about ads on the web pages, and about the platform gap this whole post is built around.

What pushes someone to search "PDF24 alternative"

Five moments come up again and again:

• You need to merge or compress a file on a Mac, a Chromebook, or a phone, and the local option simply doesn't exist for that device.
• IT locked down installs on your work laptop, so Creator is off the table even though you're technically on Windows.
• You're handling something you'd rather not put on any server for even an hour: a signed contract or a medical form.
• You tried the web tools, they worked fine, then you read the retention policy and wanted a version that skips the upload step entirely.
• You tapped "install as an app" on your phone expecting Creator's local processing, and got the same upload with a home-screen icon instead.

PDF24 doesn't have a good answer to any of these beyond "use a different computer" or "accept the upload."

Where OxygenPDF sits

OxygenPDF runs the whole toolkit locally, in your browser tab. Most tools, merge, split, sign, redact, watermark, run against the file already sitting in your browser's memory using standard JavaScript PDF libraries; a few of the heavier ones, like OCR and table extraction, lean on a dedicated WebAssembly engine for speed. Either way nothing leaves the tab, and there's no installer, so there's no operating-system gate: the local processing PDF24 promises on Windows works identically on a Mac, a Chromebook, a Linux box, or a tablet. Open DevTools, watch the Network panel while you process a file. It stays empty.

A non-exhaustive map:

• Merge PDF — combine files locally, on whatever machine you're holding
• Compress PDF — shrink a scan without a server ever seeing it
• Edit PDF — fix a typo or drop in an image, no install required
• OCR PDF — make a scan searchable without uploading it anywhere
• Sign PDF — sign a form on the Chromebook that could never run Creator
• Redact PDF — remove sensitive text for real, still with no server involved

PDF24's catalog is wider on raw tool count, and its fax service and PDF/A archival tools cover ground OxygenPDF doesn't chase. If you're on Windows, don't mind the install, and your jobs fit inside Creator, keep using it. It earns its place.

Here's that same comparison as plain text too, since a diagram doesn't survive copy-paste, a screen reader, or a text-only summarizer:

Other free PDF tools worth comparing

PDF24 isn't the only "free" tool with an asterisk attached. If the local-processing gap here doesn't apply to your situation, but the price tag on some other tool does, three more comparisons on this blog cover the other common walls:

• Sejda caps free accounts at three tasks per hour, a limit built to push you toward a paid plan rather than a technical ceiling.
• Smallpdf is a well-built Swiss tool that still stops free users at two conversions a day.
• iLovePDF earned a real 4.9 Trustpilot score off roughly 250 million monthly visits, and still caps every free tool by file size.

Every one of them, PDF24 included, uploads your file before doing anything to it. The question worth asking isn't just which free tier is most generous. It's whether the job needs to leave your device at all.

FAQ

Is PDF24 actually free?

Yes, for both products. There's no premium tier, trial countdown, or feature paywall for end users; PDF24's own tools page says outright that "you can use all PDF24 tools free of charge and without any restrictions." The company funds this through what its FAQ calls "discreet advertising on the websites," not by squeezing free users toward a paid plan the way most PDF tools do.

Does PDF24 Creator work on Mac or Linux?

No. PDF24 answers this directly on its own download page: "the PDF24 Creator can only be installed on Windows systems. Linux and MAC are not currently supported." Creator supports Windows 10 and 11 only, with no stated roadmap to change that after nearly twenty years of development.

How long does PDF24 keep my uploaded file?

One hour, according to its own FAQ: "uploaded files in the online tools are automatically deleted from the server after one hour." Its privacy policy adds that the file isn't looked at or backed up during that hour, and that both the upload and the download run over SSL.

Is installing PDF24 "as an app" on my phone the same as using Creator?

No, and this is the detail most likely to trip someone up. The phone option is a Progressive Web App: an icon that opens the same tools.pdf24.org site in its own window. Tap it, pick a tool, and your file still uploads to PDF24's server exactly the way it would in an ordinary mobile browser tab. Only the Windows desktop app processes files without uploading them anywhere.

Does PDF24 show ads on the same page where I upload my file?

Yes. PDF24's ad-supported model runs Google AdSense, Google AdWords, and an anonymized Google Analytics integration on its tools pages, disclosed in its own privacy policy. That's a separate question from whether your file itself is shared with those services, but it's part of the same page load your file passes through while it's being processed.

Is there a PDF tool that never uploads my file, on any device?

Yes. OxygenPDF runs every tool in the browser tab you're already in, with no installer and no platform check, so merging, editing, or signing a file works the same way on a Mac, a Chromebook, or a locked-down work laptop as it does on a Windows PC with admin rights.

The narrow point

PDF24 isn't a bait-and-switch. It's free, honestly free, built by a small German team that's kept the lights on with ads instead of paywalls for two decades. The one-hour retention window on its web tools is short and disclosed in plain language, which is more than most competitors manage.

The gap is narrower and more specific than most "alternative" posts want it to be. Local processing exists at PDF24. It just only ships for one operating system. Everyone else, Mac, Chromebook, Linux, tablet, or a locked-down office laptop, gets the upload regardless, whether that upload happens in a browser tab or behind a home-screen icon that looks like it should be different. Drop a file into Merge PDF or Edit PDF and the local option just works, no matter what's printed on the case.
