I built 100+ free browser tools so people stop uploading private files to cloud servers

说明与用途

SuperToolKit 是一套 100+ 浏览器工具，完全在本地内存中运行，消除了云上传、广告和使用限制，并支持离线使用。

问题

Existing online converters force users to upload sensitive files to remote cloud servers, impose daily limits, and display ads.

结果

SuperToolKit eliminates the need to upload private files to cloud servers, removes usage limits and ads, and enables offline operation.

工作流

• Open SuperToolKit in the browser
• Select desired tool (audio editor, PDF merger, etc.)
• Upload or drag files into the tool
• Processing occurs locally via WebAssembly and Web Workers
• Download or use the result directly in the browser

证据

SuperToolKit handles the work directly inside your browser sandbox using WebAssembly, the Web Audio API, and background Web Workers.

Your device's hardware does the computing. Audio editing, PDF merging, and file conversions happen in local memory—nothing ever gets sent across the internet.

Built as a Progressive Web App (PWA) with service worker caching, so all utilities work even in airplane mode.
