Files.co PDF Suite is now on your desktop — for Mac and Windows

For a while now, files.co has lived in a browser tab. You drop a PDF in, you merge or sign or compress it, and the file never touches a server. That model works beautifully for a quick job. But some of you told us the same thing over and over: I love that it stays on my machine — I just wish it were an app I could keep open all day.

So we built one. Files.co PDF Suite is now a native desktop app, and today it’s available on both the Mac App Store and the Microsoft Store.

Two stores, one app, zero uploads

The desktop app is live and free to download right now:

• macOS — get it on the Mac App Store. Runs on Apple Silicon and Intel, macOS 13 or later.
• Windows — get it on the Microsoft Store. Windows 10 and 11, 64-bit.

You can see everything it does, with screenshots, on the Files.co PDF Suite page.

The thing that made the website worth using is the same thing that makes the app worth installing: your documents are processed on your own computer. There’s no upload, no account, no cloud folder quietly holding a copy. Cut its network access entirely and it keeps working — because it never needed the network in the first place.

What a desktop app gives you that a tab can’t

If the browser version already does the job, why install anything? A few reasons that only really click once you’ve used it.

A real tabbed viewer. Open several PDFs at once, each in its own tab, and jump between them like you would in a browser. It’s a proper reader, not just a tool that spits out a file — thumbnails down the side, a reading mode, the works.

Annotations that live inside the PDF. Highlight a clause, scribble a note, draw an arrow. When you save, the marks are written into the document itself, so they travel with the file wherever it goes.

Big files stop being a problem. Browsers run out of memory on genuinely large PDFs — the 400-page scanned manual, the high-resolution portfolio. A native app uses your machine’s real RAM and disk, so those files open and process without hitting a wall.

It belongs to your system. Open PDFs straight from Finder or File Explorer, drag them onto the app’s icon, and set files.co as your default PDF handler if you want. It behaves like software that lives on your computer, because it does.

It works on a plane. Not even the first launch needs internet. For air-gapped offices, sensitive documents, or a long flight with no Wi-Fi, that’s the whole point.

Fifteen tools, free forever

The app ships with fifteen PDF tools in the free tier, and free here means free — no trial clock, no watermark, no “sign in to continue.” You get merge, split, compress, rotate, reorder, crop, bookmarks, protect, unlock, images-to-PDF, extract text, page numbers, header and footer, watermark, and PDF-to-images. Everything runs locally.

The interface is translated into seven languages — Spanish, English, French, German, Italian, Portuguese, and Dutch — switchable instantly from the app’s settings.

There’s a future Pro plan on the horizon that will add the heavier power tools: batch processing across many files at once, OCR for scanned documents, eIDAS signing, comparing two PDFs, filling forms, exporting to PDF/A, maximum compression, and no size limits. We’re not putting a price on it yet — when Pro launches, we’ll tell you exactly what it costs, here on the blog first.

The same idea, a bigger home

Nothing about the promise has changed. The reason people trust files.co in the browser is that the privacy isn’t a setting you switch on — it’s how the thing is built. The desktop app inherits that wholesale. No telemetry on your files, no uploads, no server round-trip. The only difference is that now it’s a window you can pin to your dock or taskbar and reach for whenever a PDF lands in your inbox.

If you’ve been waiting for the Mac version, the wait is over. And if you’re on Windows, it’s been ready for you too.

Grab it from the Mac App Store or the Microsoft Store, or read the full rundown on the PDF Suite page. And if you’d rather not install anything at all, the twenty browser tools are right where you left them — still uploading nothing.
