FunnyTools, also known as FreeTools, is a free online toolbox that provides browser-based utilities for common document, image, text, and calculation tasks. The platform is designed to operate without requiring users to install software or create an account. It focuses on practical tools for work, teaching, PDF management, image editing, writing, random selection, and everyday estimates. Most tools function directly within a mobile or desktop browser, and users can add frequently used tools to a favorites list for quicker access. The main features include tools for merging, splitting, converting, and rotating PDFs locally in the browser. Image utilities allow users to compress, resize, and convert PNG or JPG files. The platform also includes QR code generation, random pickers, timers, and calculators for salary, overtime, mortgages, compound interest, and business day planning. For educators, there are tools for picking students, splitting classes, arranging seats, and calculating grade averages. Each tool page explains its workflow and any relevant data handling limits, with an emphasis on local browser processing. Typical use cases include office document preparation, classroom activity management, and personal productivity. For example, a teacher can prepare a student list, create random groups, pick speakers, set a countdown timer, and save the result. Graduate students can use a workflow to turn statistical output into a checkable report draft by confirming descriptive statistics, inspecting assumptions, and generating APA 7 sentences. Teacher exam candidates can organize scores for written, demo teaching, interview, and portfolio components into a calculation, then interpret T, Z, or percentile rank positions. Technically, the platform is accessible via any modern web browser on phones, tablets, or desktop computers. No app installation or account registration is necessary. The tools prioritize local processing, and the website labels data handling and usage notes on individual tool pages. Users can browse tools by category, search by keyword, or view popular and recently used tools. The platform is hosted at funnytools.win/en.
