🔐 Base64 Encoder/Decoder
Encode and decode Base64 strings
Frequently Asked Questions
What is Base64 encoding used for?
Base64 encoding converts binary data into ASCII text format. It's commonly used for embedding images in HTML/CSS, sending data in URLs, email attachments, and storing complex data in text-based formats like JSON or XML.
Does Base64 encoding encrypt my data?
No, Base64 is NOT encryption - it's simply an encoding method. Anyone can decode Base64 strings. Never use Base64 alone to protect sensitive information; use proper encryption instead.
Can I encode special characters and emojis?
Yes! This tool uses UTF-8 encoding, which supports all Unicode characters including special characters, emojis, and non-Latin scripts like Chinese, Arabic, or Cyrillic.
Why does my encoded string contain only letters and numbers?
Base64 uses a limited character set: A-Z, a-z, 0-9, +, /, and = for padding. This ensures the encoded data is safe to transmit through systems that might not handle special characters well.
