What is Plain Tools?
Plain Tools is a privacy-first collection of browser utilities for everyday tasks such as file conversion, networking diagnostics, and developer tools. All tools run locally on your device without uploading files to external servers.
Unlike traditional online tools that process your files on remote servers, Plain Tools uses modern web technologies like WebAssembly and Web Workers to perform all operations directly in your browser. This means your sensitive documents, images, and data never leave your device.
Every tool is designed with three principles: speed (no upload/download delays), privacy (no server-side processing), and transparency (open source and verifiable). Whether you need to compress a PDF, look up DNS records, or convert file formats, Plain Tools provides fast, secure, and completely private solutions.
