Kit-Bin: Client-Side File Tools for Privacy

Описание и применение

Kit-Bin — это набор инструментов для работы с файлами, которые работают полностью в браузере. Это решает проблему конфиденциальности, так как файлы не загружаются на сторонние серверы. Пользователи могут проверить отсутствие передачи данных через инструменты разработчика.

Задача

Free online file converter and tool sites often require uploading sensitive files (PDFs, images with EXIF data, work documents) to third-party servers, posing privacy and security risks despite deletion policies.

Результат

A privacy-focused file tool suite that processes files locally in the browser, eliminating the need to upload sensitive data to third-party servers. Users can technically verify the lack of data transmission via browser devtools.

Рабочий процесс

• Navigate to the Kit-Bin website.
• Select a tool category (e.g., PDF, Image, Audio, Video, Data, Developer).
• Open browser Developer Tools and select the Network tab.
• Upload or select the local file for processing.
• Execute the desired operation (e.g., merge, convert, strip metadata).
• Observe that no network requests containing file data are sent during processing.
• Download the processed result directly from the browser.

Доказательства

Open your browser's devtools, go to the Network tab, and use any tool on the site... Watch the network requests while it processes. You'll see the page's own static assets load once, and then nothing

Источник

every tool runs entirely client-side, in JavaScript/WASM, in your browser tab. There's no upload step, because there's no server on the other end doing the processing.
