Encode and decode Base64 strings for text and files. Perfect for data transmission, API integration, and file encoding.
All encoding and decoding happens in your browser. Your data never leaves your device.
Encode any file type to Base64 or decode Base64 back to files with download support.
Real-time processing with immediate results for both text and file conversions.
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. Its commonly used for:
Base64 encoding is essential for:
When working with Base64:
Base64 is encoding, not encryption. Its easily reversible and should not be used for security purposes. Use proper encryption for sensitive data.
You can encode any file type to Base64 - images, documents, videos, executables, etc. The tool handles all binary data.
Base64 encoding increases file size by approximately 33% because it uses 4 ASCII characters to represent every 3 bytes of binary data.
You can decode any valid Base64 string. Invalid characters or incorrect padding will result in an error message.
