What is Base64?

This tool converts between files and Base64 so binary data can be represented as text (or restored from it). It is handy for embedding files in text formats and for moving binary data through text-only channels.

How to use

  1. Select or drop your file (or paste Base64 data).
  2. The conversion runs locally in your browser.
  3. Download or copy the result.

Common uses

  • Safely storing or transmitting data through text-only systems.
  • Embedding data in URLs, JSON, XML or HTML.
  • Moving binary data across channels that expect text.

Frequently asked questions

Is my file private?
Yes — the conversion happens entirely in your browser and the file is never uploaded.
