What Base64 Encoding Does

Base64 converts text or binary-safe data into an ASCII string that can travel through APIs, headers, JSON fields, data URIs, and systems that do not handle raw bytes well.

Encode vs Decode

Encode when you need Base64 output from plain text. Decode when you want to inspect a Base64 string and turn it back into readable text. Watch for padding, Unicode characters, and line breaks.

Security Reminder

Base64 is not encryption. Anyone can decode it. Do not treat Base64 output as a safe way to hide passwords, secrets, private keys, or sensitive data.

Frequently Asked Questions

Is Base64 encoding a form of encryption?

No. Base64 is encoding, not encryption. It changes the representation of data but does not protect it. Anyone with the encoded string can decode it instantly.

Why does Base64 output end with == signs?

Base64 pads the output with equals signs when the input length is not a multiple of three bytes. It is part of the standard format, not an error.

Can I encode binary files with this tool?

The tool handles text input. For encoding binary files such as images, use the URL or data URI encoding options provided alongside the text encoder.

What This Tool Does

Base64 Converter encodes plain text or binary data into Base64 format and decodes Base64 strings back to their original content. It is used in web development, email encoding, API authentication headers, and embedding small assets directly in HTML or CSS.

Typical Use Cases

Use this when an API expects credentials in Base64-encoded form, when inspecting the payload of a JWT token, when embedding a small image as a data URI, or when decoding an encoded string received from an external service.

Step by Step

Select Encode or Decode mode.
Paste your text or Base64 string into the input area.
Click Convert to produce the output.
Copy the result with one click.
