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.

Features

• Client-side tool execution
• Static export with next build
• Search, category filtering, favorites, recent tools, compact mode, full width mode, dark mode
• Command palette with keyboard navigation
• PWA install support
• Native desktop wrapper support (Tauri v2) for Windows, macOS, and Linux
• Responsive layout for desktop and mobile

Tool Categories

• Converters: 11 tools
• Encoders & Decoders: 10 tools
• Generators: 9 tools
• Formatters & Validators: 5 tools
• Text Tools: 11 tools
• Utilities: 9 tools
• Security: 8 tools
• Networking: 6 tools
• Design: 6 tools
• PDF Tools: 4 tools
• Image Tools: 5 tools
• Calculators: 11 tools

Counts are the tools listed on the home page under each tag (80 in total); a tool can carry more than one tag. The two PDF pages bundle nine PDF tools as tabs, and the image converter includes resize, crop, compress and icon export.

See ROADMAP.md for planned work and expansion backlog.
