How TofuwebtoolsWorks
Browse the index
100+ tools, searchable in one place. Filter by category or search by name.
Built to stay out of your way
One idea holds the whole toolbox together: your tools shouldn't cost you your privacy, your time, or your wallet.
One tab, not twenty
Every formatter, converter, and generator you'd normally hunt for across a dozen sites, sitting in one fast, focused toolkit instead.
Nothing leaves your browser
Every calculation, conversion, and file you drop in is processed on-device. Open the network tab if you don't believe us — there's nothing to see.
Complete tools, zero paywalls
No trial limits, no "upgrade to export," no account wall. Every tool ships finished and stays free — that's the whole business model.
Asked, answered.
Everything people usually want to know before diving in.
Yes — every tool is fully free to use, with no signup, no usage limits, and no premium tier hiding key features.
Nowhere. Processing runs locally in your browser using JavaScript and Web APIs. Nothing you enter is uploaded to a server.
Most tools work fully offline once the page has loaded, since all processing happens on your device.
Yes, within the limits of your browser's memory. Very large files may be slower since everything runs on your device rather than a server.
No. The tools on Tofuwebtools.com are free forever — there's no plan to introduce paywalls for existing functionality.
No account, no login, no email required. Every tool is available the moment you open the page.
Any modern browser — Chrome, Edge, Firefox, or Safari. Since everything runs on the Web APIs built into your browser, there's nothing extra to install.
Yes — the toolset is actively growing. If there's a utility you rely on elsewhere, reach out and it may be added to the index.
