About Toolk
Toolk brings together 103 online tools for work, study and everyday tasks. Use it to prepare PDFs, convert images, edit writing, calculate values or work with code and data. 103 current tools are marked free and open without signup. Choose a task, follow the tool's instructions and download or copy the result.
Access and pricing are properties of each tool, not a permanent platform promise. All 103 tools in today's catalogue are marked free and open without signup. An existing free tool will not be retroactively placed behind a paywall.
Every tool runs 100% client-side in your own browser using JavaScript. Your tool input — JSON payloads, API keys, passwords, files, image bytes — never leaves your device and is never transmitted to any server we control. For page-use measurement, Google Analytics 4 receives page, session, device, browser, and approximate-location information. Tool input is never included in that telemetry. Read the privacy policy for the complete disclosure.
Toolk is built and maintained by M H Tawfik under Soft Web Grove. The full mission statement, principles, and contact details are on the About page.
