Quick answer
Yes — PDFsmith is a one-time-purchase alternative to SmallPDF. It costs $29 once, while SmallPDF runs $12–15/mo — about $144 per year, every year. Merge, split, rotate, watermark & convert PDFs offline. No uploads, ever. It is for people who want the job done on their own hardware without a renewal date — not for teams that live inside SmallPDF's ecosystem.
The verdict
Switch to PDFsmith if you are an individual or small team paying SmallPDF $12–15/mo for work your own machine can do. Two and a half months of SmallPDF pays for PDFsmith outright. Everything after that is money you keep.
Stay with SmallPDF if your workflow depends on its integrations, you need enterprise features (SSO, admin controls, SLAs), or your team is large enough that per-seat collaboration tooling is worth the bill. PDFsmith does not try to replicate those.

Where SmallPDF still wins
- Ecosystem and integrations. Established tools accumulate years of third-party integrations, templates and add-ons. If your workflow is wired into SmallPDF's ecosystem, switching means rebuilding that plumbing — a real cost.
- Team and enterprise features. Shared workspaces, granular permissions, SSO, audit logs and a vendor to call when something breaks — that is what the higher subscription tiers actually buy, and a pay-once app does not come with it.
- Familiarity and hiring. SmallPDF is the name people already know. Onboarding a team onto a tool nobody has used before takes time the subscription never charges for.
Where PDFsmith wins
- Price, permanently. $29 once versus $144/yr for as long as you use it. There is no renewal, no seat count and no tier gate.
- Merge PDFs. Drag-drop any number of PDFs, reorder them in the list, combine into one file.
- Split PDF. Extract any page ranges (1-2 | 3 | 4-6) into separate new PDFs.
- Rotate pages. 90° / 180° / 270°, all pages or a specific range, batched across files.
The math
Two and a half months of SmallPDF pays for PDFsmith outright. Everything after that is money you keep.
- After 1 year: PDFsmith has cost you $29 total — SmallPDF has cost $144.
- After 3 years: PDFsmith is still $29 — the subscription is at $432.
- After 5 years: PDFsmith is still $29 — the subscription is at $720.
Common questions
Is it really free on GitHub?
Yes. The full source code is MIT-licensed at github.com/bensblueprints/pdf-toolkit-mvp 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.
