Processing
Convert any file (images, documents, archives, media) into Base64 code instantly. Generate raw Base64 strings, Data URIs, CSS code, or HTML tags locally.
Add files to encode
Security first: your assets are read and encoded on your local device. Absolutely zero files or contents are uploaded to the internet or Zrubix servers.

Get your Base64 exactly how you need it. Choose from standard Data URI strings, raw Base64 data, CSS background-image codes, or pre-formatted HTML tags ready to paste into your files.
Upload and encode dozens of files at the same time. All parsing is handled using web stream APIs in your browser sandbox, keeping your documents confidential.
Base64 strings can contain millions of characters. Our converter features intelligent view rendering buffers to prevent browser layout freezing, ensuring a premium developer experience.
Base64 encoding allows binary data—like images, icons, or PDF files—to be represented in standard ASCII strings. By doing so, you can directly embed files into your source code (like CSS background-images, HTML img sources, or JSON payloads). This eliminates extra HTTP server requests and improves web loading speeds.
Our converter is the ideal workflow partner for modern web engineers. By wrapping file conversion in an easy-to-use batch logic client, Zrubix lets you bypass scripting and instantly obtain clean, correctly formatted code blocks for files of any size.
Because files like PDFs, images, and documents often contain private information or company assets, sending them to external servers is a security risk. Zrubix operates completely client-side. The file data never leaves your computer; your web browser handles all binary-to-text formatting logic locally.
This means you can encode private company credentials, user documents, or personal images safely. Experience total privacy combined with the convenience of a modern web application.
