Free browser tools that run locally
Convert, decode, format, and inspect common web data without uploading your files. CleanWebTools is built to do one task well per page, with a privacy-first workflow that keeps your input in the browser.
Start with a focused tool
Each page solves one search intent with a real browser-based utility, practical examples, privacy notes, and links to related tools.

Built for search, speed, and trust
CleanWebTools uses static pages so every utility can have a clear title, canonical URL, readable explanation, examples, and structured data. The product is not a single hidden app behind one route; it is a collection of focused pages that each answer one specific user task.
CleanWebTools avoids aggressive advertising and heavy media. The priority is useful tools, clean content, fast loading, accessible controls, and a clear promise: many common conversions can happen directly in the browser.
