Built for privacy.
360 tools from the Netherlands. Nearly all of them run in your browser and upload nothing. The few that cannot say so on the page, before you type anything into them.
Most tool sites ask you to upload first.
Most online tool websites follow the same model: you upload your file to their server, they process it, and you download the result. This creates unnecessary privacy risks, depends on a server being available, and often comes with file size limits designed to push you toward a paid plan.
ToolForte takes a different approach. Nearly every tool processes data directly in your browser using JavaScript and WebAssembly. Your files, passwords and code snippets never leave your device. The exceptions are real and they are named below, because an exception you have to discover is worse than one you were told about.
Browser-based processing.
Modern browsers provide powerful APIs: the Canvas API for image manipulation, the Web Crypto API for secure random number generation, WebAssembly for near-native performance on heavy tasks like PDF processing.
A PDF you merge on ToolForte never touches a remote server. A password you generate is created using cryptographically secure randomness on your device. The privacy benefit is inherent to the architecture, not a policy promise.
The exceptions, and our bot
Some tools cannot work this way, and they do not all fail the same way, which is worth separating because the answer to "who sees this" is different in each case.
17 tools send what you typed to our own server. Four of them look at a website that is not ours to load: the meta tag checker, the HTTP headers checker, the canonical checker and the broken link checker. Our server fetches the page and hands back the result, and we do not store the address or the response. The other 13 are the AI writing tools, where what you type goes to our server and on to the model provider that generates the answer. We keep a record that the call happened, for your usage history, and not what was in it.
5 tools do something different again, and the previous version of this page described it wrongly. The currency converter, the DNS lookup, the domain checker, the WHOIS lookup and the IP address lookup do not go through us at all: your browser asks an outside service directly. We never see what you looked up, and we also cannot promise anything about what that service keeps, so each of those pages names the service and links to its policy instead of reassuring you on its behalf. Not reaching us is not the same as not leaving your machine.
Everything else on the site stays in your browser. 30 tools also remember your work between visits, which they do in your own browser rather than in an account, so it is on that one device and we cannot recover it for you. Every tool page says which of these it is.
If you run a website and see ToolForteBot in your logs, that is one of those checks: a visitor asked us to look at a page of yours. It requests only the address that was entered, follows at most four redirects, never crawls beyond the page itself, and reads at most two megabytes. The broken link checker additionally asks for the status of up to forty links found on that one page. If you would rather it stayed away, block the user agent ToolForteBot. Nothing here depends on ignoring that.
Built in the Netherlands.
ToolForte is built and maintained in Utrecht, the Netherlands, by Toine, a test manager with nineteen years in software testing and quality assurance for banks, insurers, pension administrators and government. The site grew out of his own daily work, and he also writes the blog. The same small jobs kept coming back, week after week: formatting JSON from a log file, validating an IBAN, generating GDPR-safe test data, converting a file, checking a cron expression. Each one small enough that opening a heavyweight application felt wrong, and common enough that hunting for a trustworthy website every time got old fast.
So we built the toolbox we wanted to use ourselves: every recurring job as a fast, browser-based tool that does not ask for an upload, an account, or your data. What started with a handful of developer utilities has grown into hundreds of tools, a REST API, and an MCP server, because the same recurring jobs that bother people also bother scripts and AI agents.
Every tool is built with care for privacy, performance, and usability, and tested against the standards we are used to from regulated industries. We actively maintain and expand the collection based on user feedback and our own recurring work.
