Base64 Encode
Encode text to Base64 format
Enter any text to encode to Base64 format
What is Base64 Encoding?
Base64 is an encoding scheme that converts binary data into ASCII text format. It's commonly used to encode data in emails, URLs, and data URIs. This tool properly handles UTF-8 characters, ensuring international text is encoded correctly.
How to Use
- Enter or paste the text you want to encode
- Click "Encode to Base64"
- Copy the Base64 result using the "Copy to Clipboard" button
Example
Input:
Hello, World!Output:
SGVsbG8sIFdvcmxkIQ==Common Use Cases
- Encoding binary data for transmission over text-based protocols
- Embedding images in HTML/CSS using data URIs
- Encoding credentials for HTTP Basic Authentication
- Storing binary data in JSON or XML
- Encoding email attachments (MIME)
UTF-8 Support
This tool properly handles UTF-8 encoding, so you can safely encode text containing international characters, emojis, and special symbols.
Frequently Asked Questions
What is Base64 encoding used for?
Base64 encoding is used to convert binary data into ASCII text format, making it safe to transmit over text-based protocols like email, HTTP, and JSON. It's commonly used for embedding images, encoding credentials, and handling binary data in text contexts.
Does Base64 encoding encrypt my data?
No! Base64 is an encoding scheme, not encryption. Anyone can decode Base64 data. Never use Base64 alone to protect sensitive information - use proper encryption instead.
Why does Base64 make data larger?
Base64 encoding increases data size by approximately 33% because it represents 3 bytes of binary data using 4 ASCII characters. This overhead is the trade-off for making binary data text-safe.
Is my data sent to a server?
No, all encoding happens in your browser. Your data never leaves your device, ensuring complete privacy and security.
