Building 30+ Client-Side Web Tools with Zero Server Uploads

Описание и применение

Автор создал MiniTools — набор из 30+ веб-инструментов, работающих полностью на стороне клиента. Это решает проблему конфиденциальности, так как файлы не загружаются на серверы, и проблему платных сервисов. Инструменты включают обработку PDF, оптимизацию изображений и калькуляторы.

Задача

Most online utility sites force users to upload private documents (contracts, invoices, IDs) to unknown third-party servers and often impose paywalls or forced registration after minimal usage.

Результат

A suite of 30+ tools including PDF manipulation, image compression (with specific size limits like 30KB/50KB), format converters, and calculators, all running 100% client-side with no server uploads.

Рабочий процесс

• User selects a file (PDF, Image, etc.) on their local device.
• The browser loads the necessary libraries (e.g., pdf-lib, WebAssembly).
• Processing (merging, compressing, converting) occurs entirely in the browser's memory.
• The resulting file is downloaded directly to the user's device without ever being uploaded to a server.
• Service workers cache the application for offline use.

Доказательства

MiniTools performs every operation directly inside your browser memory
