🔍 Common Use Cases:

  • ✅ Embed images in HTML/CSS (data URLs)
  • ✅ Encode binary data for JSON/XML transmission
  • ✅ Obfuscate sensitive data in URLs
  • ✅ Store small files in databases
  • ✅ Email attachments (MIME encoding)
  • ✅ API authentication tokens
  • ✅ Web storage of small assets
  • ✅ Cross-platform data exchange
⚠️ IMPORTANT NOTES:
  • Base64 is NOT encryption - it's encoding
  • Base64 increases size by ~33%
  • Always validate Base64 before decoding
  • Watch for padding characters (= or ==)

Common questions and solutions

❓ FREQUENTLY ASKED QUESTIONS

Q: Is Base64 encryption?
A: NO! Base64 is encoding, not encryption. Anyone can decode Base64 back to the original text. It's not secure for sensitive data.
Q: Why does Base64 have = or == at the end?
A: These are padding characters. Base64 works in 3-byte blocks. If data isn't divisible by 3, = signs are added to make it complete.
Q: What's URL-safe Base64?
A: Regular Base64 uses + and / which have special meanings in URLs. URL-safe replaces + with - and / with _.
