What is Base64 encoding and why is it used?

Base64 encoding is a method of converting binary data into ASCII text format by translating it into a radix-64 representation. It's commonly used when binary data needs to be stored or transferred in environments that only support text, such as email attachments, embedding images in HTML/CSS, storing complex data in JSON, and API authentication tokens.

How do I use the Base64 Encoder/Decoder?

Using our Base64 tool is simple: select the operation (encode or decode), enter your text or upload a file, and click the process button. For encoding, you can also choose character encoding options. For generating secure random Base64 strings, specify the desired length and click generate. Results can be copied to clipboard or downloaded as needed.

Is my data secure when using this tool?

Yes, your data is completely secure. All processing happens directly in your browser - your information is never sent to our servers. This ensures that sensitive data stays on your device and isn't transmitted over the internet.

Base64 Encoder/Decoder & Secret Generator

Convert text to and from Base64 encoding, and generate secure random Base64 secrets for API keys, tokens, and authentication.

Convert text and files to and from Base64 encoding for data transmission and storage. Development utilities streamline workflows and increase productivity. Our utility provides solutions to common challenges faced by developers. Our tool supports Text and file encoding/decoding with multiple character set options.

Encode text to Base64, decode Base64 to text, or generate cryptographically secure random Base64-encoded secrets for API keys, tokens, and authentication.

How to Use the Base64 Tool

Encoding/Decoding:

Enter Data: Paste or type the text string you want to encode, or the Base64 string you want to decode, into the input area.
Choose Action: Click "Encode to Base64" to convert plain text to Base64, or "Decode from Base64" to convert Base64 back to plain text.
View Output: The result will appear in the output area below, ready to copy and use in your applications.

Generating Secure Secrets:

Click "Generate Secret" to create a cryptographically secure random token.
A 32-byte (256-bit) random secret, Base64 encoded, will appear in the output area. This provides strong security for API keys, tokens, and other sensitive credentials.
Use the "Copy" button to copy the generated secret for immediate use in your applications.

What is Base64? Base64 is an encoding scheme that converts binary data into an ASCII string format by representing binary data in a 64-character set (A-Z, a-z, 0-9, +, /). It's commonly used for:

Embedding binary data in text-only formats (like JSON, XML, HTML)
Encoding email attachments (MIME)
Storing complex data in cookies or localStorage
Creating API keys and authentication tokens
Encoding binary data in URLs (with URL-safe variants)

Common Use Cases: Embedding images in HTML/CSS, encoding authentication credentials, preparing binary data for API requests, creating JWT tokens, and generating secure random secrets for development.
