LazyTools Collection

A privacy-first collection of browser-based web utilities, developer tools, and productivity helpers built with Next.js App Router, React, shadcn-style components, Tailwind CSS, and static export.

Live at: lazytools.dev

About

A privacy-first static web app and native desktop application for everyday browser-side and offline workflows: converting files, processing PDFs, compressing images, formatting code and data, generating values, editing text, calculating metrics, and managing general utilities — without sending user content to a server. All tool interactions run completely locally (in the browser or native desktop webview); the site is generated at build time.
