Private by design

Files are processed on your device by your browser. Nothing is uploaded, logged or stored.

Instant results

No upload or download queue. Most tasks finish in seconds — many tools even work offline.

Free forever

Every tool is free with no watermark. Heavy users can go Pro to remove ads and batch limits.

Frequently asked questions

Are my files uploaded to a server?

No. Every ToolSmith tool runs locally in your browser. PDFs, photos, text and recordings never leave your device, so they stay private — and there is no waiting for uploads.

Is ToolSmith really free?

Yes. All 54 tools are free to use, supported by unobtrusive ads. If you use them a lot, ToolSmith Pro removes ads and batch limits with a one-time payment.

Do I need to create an account?

No. There is no sign-up and no login. Open a tool and start using it.

Does it work on my phone?

Yes. The tools work in any modern browser on Windows, macOS, Linux, iPhone, iPad and Android.
