Base64 Encoder/Decoder

How It Works

Our Base64 encoder/decoder tool converts text or data into a Base64 string or decodes a Base64 string back to its original form. Enter your text, choose to encode or decode, and copy the result instantly.

Why Base64 Matters

Base64 encoding transforms binary or text data into a text-friendly format, widely used for embedding data in web applications, APIs, or emails. Decoding lets you retrieve the original content, making this tool valuable for developers and data handlers.

Tips for Using Base64 Encoding/Decoding

• Encode sensitive data like passwords or tokens before transmitting them.
• Decode Base64 strings to recover original text for analysis or use.
• Use Base64 for embedding images in HTML or CSS.
• Copy the result directly for use in code or configurations.
• Check decoded output to ensure it matches your expectations.

Frequently Asked Questions

Q: What is Base64 encoding?

A: Base64 encoding converts binary or text data into an ASCII string using 64 characters (A-Z, a-z, 0-9, +, /), making it safe for text-based systems.

Q: Why would I decode a Base64 string?

A: Decode Base64 to retrieve the original data, such as text or files, from an encoded format.

Q: Is Base64 encryption?

A: No, Base64 is not encryption—it’s an encoding method. It obscures data but doesn’t secure it cryptographically.

Q: Are my encoded/decoded results stored?

A: No, we don’t save your input or output. Everything remains private and temporary.

Additional Base64 Tips

• Use Base64 for API payloads to encode complex data safely.
• Verify decoded data to catch invalid Base64 strings early.
• Avoid encoding already Base64-encoded data—it doubles the size unnecessarily.
• Test Base64 strings in your target application to ensure compatibility.
