About simpletool.io
A privacy-first, ad-supported collection of 76 free browser-based utilities — and the people and principles behind it.
Our mission
simpletool.io exists to be the fastest, least annoying free tools site on the internet. The web is full of utility sites that work — and also bury the tool behind pop-ups, newsletter gates, 15 ad slots per page, and watermarked outputs. Our goal is a small, well-built utility on every page, surrounded only by the context that makes it useful, and supported by a conservative amount of advertising.
How we think about ads and monetisation
The site is ad-supported. We use Google AdSense with a strict two-slot-per-page maximum, never placing an ad above the tool itself. If we move to a better ad partner (Ezoic, Mediavine) we will keep the same density rules. No sponsored content will be disguised as editorial, and affiliate links (if any appear) will always be disclosed inline.
Privacy, in practice
Every tool runs in your browser. Image tools use the HTML canvas API. Text tools use JavaScript string operations. Hash tools use the browser's native Web Crypto API. For the handful of cases where a server is unavoidable (contact form, email newsletter), we use privacy-respecting third parties with their own clear policies. We do not run fingerprinting, session replay, or behavioural ad retargeting.
Performance as a feature
Every page is pre-rendered at build time and ships a small HTML document to the browser. Heavy tool libraries are loaded only when you interact with the tool, so pages stay fast even on older devices. We benchmark Core Web Vitals on every tool release. A tool that lands with bad Core Web Vitals is held back until it is fixed.
