Base64 Encoder & Decoder

How to Use Base64 Encoder

1. Select whether you want to encode (text/file to Base64) or decode (Base64 to text)
2. For encoding: paste text or drag/drop a file into the input area
3. For decoding: paste the Base64 encoded string into the input field
4. The conversion happens instantly in real-time as you type or upload
5. Copy the result using the copy button for immediate use
6. Toggle between URL-safe and standard Base64 encoding as needed

Common Use Cases

• **Web Development**: Embed images directly in CSS or HTML using data URIs
• **API Integration**: Encode credentials or binary data for secure transmission
• **Email Attachments**: Convert files to Base64 for embedding in email systems
• **Database Storage**: Store binary files as text in databases that don't support BLOB
• **Configuration Files**: Encode sensitive data in JSON or XML configuration files
• **Data Transfer**: Safely transmit binary data through text-based protocols like HTTP

Why Use Base64 Encoder?

Tips & Best Practices

• Use URL-safe Base64 encoding for data that will be used in URLs or file names
• Base64 increases data size by approximately 33% - factor this into storage calculations
• For large files, consider compression before Base64 encoding to reduce size
• Always test decoded data to ensure integrity, especially with binary files
• Use Base64 for small to medium files; large files should use dedicated file storage
• Remember that Base64 is encoding, not encryption - don't use it for security
