Base64 Encode Decode Tool
Use this Base64 encode decode tool to switch between plain text and Base64 instantly. It supports both directions in a single browser-side interface.
Example Usage
- Encode plain text before embedding it in a simple transport format.
- Decode a Base64 string from logs or payloads into readable text.
- Quickly inspect tokens, test inputs, or encoded text snippets while debugging.
Base64 Encode Decode Explained
Base64 is a text-based encoding format that turns binary or plain text data into an ASCII-safe string. It is commonly used in data URLs, tokens, simple payload wrappers, and transport scenarios where raw bytes are inconvenient. This tool lets you switch between text and Base64 in either direction without leaving the page. That is useful when debugging encoded values, checking payloads, or preparing content for APIs and browser features that rely on Base64-compatible strings. Everything runs directly in the browser, so results are immediate.
FAQ
What is Base64 used for?
Base64 is commonly used to represent binary or text data as an ASCII-safe string for transport or embedding.
Can I both encode and decode here?
Yes. The tool supports both modes from the same interface.
Why would decoding fail?
Decoding fails when the input is not valid Base64 or contains an invalid encoded sequence.
