Encode Text to Base64

Enter text into the input area and encode it into Base64 with a single click. The resulting encoded value can be copied, downloaded, or used in applications and development workflows.

Decode Base64

Paste a Base64-encoded value into the decoder to convert it back into its original text representation. The tool checks the input and provides a clear result when valid Base64 data is supplied.

UTF-8 Support

The tool should support Unicode and UTF-8 text so that developers can encode and decode more than basic ASCII characters, including international text.

Base64URL Support

A useful future enhancement is Base64URL encoding and decoding, which uses the URL- and filename-safe Base64 alphabet specified by RFC 4648. Base64URL should be treated as a distinct encoding variant rather than simply calling it standard Base64.

Designed for Privacy

ToolNTip’s Base64 Encoder & Decoder is designed for browser-based processing. When implemented entirely on the client side, your input can be processed locally in your browser without being uploaded to a ToolNTip server.

Important: Base64 Is Not Encryption

Base64 encoding does not provide encryption, confidentiality, or password protection. It is an encoding mechanism used to represent data in another form. RFC 4648 specifically notes that Base64 does not add confidentiality to the original data.

Therefore, sensitive information should not be treated as secure merely because it has been Base64 encoded.

Built for Developers

Whether you are debugging API data, inspecting encoded values, preparing data for an application, working with web development, or troubleshooting integration data, ToolNTip’s Base64 Encoder & Decoder provides a simple workspace for common Base64 operations.

Supported operations include:

• Encode text to Base64
• Decode Base64 to text
• UTF-8 text support
• Copy encoded or decoded result
• Clear input and output
• Swap input and output
• Download result
• Character count
• Byte count
• Browser-based processing

Standards

The standard Base64 implementation should follow RFC 4648, including its Base64 alphabet and padding behavior. RFC 4648 also defines a URL- and filename-safe Base64 variant known as Base64URL.
