What is Base64 encoding?
Base64 encoding converts binary data or text into ASCII characters using 64 printable characters. It's commonly used in HTTP headers, JSON, and data URLs.
How do I decode Base64 online?
Paste your Base64 string, click Decode, and the original text appears. This tool handles UTF-8 encoding for international characters.
Is Base64 encoding secure?
No, Base64 is NOT encryption. It's only encoding for data transport. Anyone can decode it. Never use Base64 alone to protect sensitive data—use proper encryption instead.
