📄 PDFsmith

Every PDF tool you actually use — running 100% on your machine.

SmallPDF charges up to $15/month, forever, to do things your computer can do for free — and it uploads your documents to their servers to do it. PDFsmith does the same jobs locally, offline, with zero telemetry, for a one-time $29.

FAQ

Honest answers

Is it really free on GitHub?

Yes. The full source code is MIT-licensed at github.com/bensblueprints/pdf-toolkit and always will be. Buying gets you the signed Windows installer, 1-click setup and updates — pure convenience, zero lock-in.

Do my PDFs get uploaded anywhere?

No. All processing runs locally with pdf-lib, a pure-JavaScript library. The app makes no network calls at all — you can run it with Wi-Fi off.

What platforms does it run on?

The packaged installer is for Windows. The MIT source runs anywhere Electron does (Windows, macOS, Linux) if you build it yourself with Node 18+.

Can it edit text inside a PDF?

No — and we'd rather tell you that upfront. PDFsmith covers merge, split, rotate, watermark, images-to-PDF and metadata. For rewriting body text inside an existing PDF you still need a full editor like Acrobat.

Is this a subscription in disguise?

No. $29 once. No renewal, no license server phoning home, no "lifetime deal" fine print. The app keeps working forever, even offline.
