tools.base64EncoderDecoder.guide.encode.steps

  1. Convert raw data to 8-bit binary stream
  2. Split every 3 bytes (24 bits) into 4 groups of 6 bits
  3. Convert each 6-bit group to Base64 index (0-63)
  4. Map to character table (A-Z, a-z, 0-9, +, /)
  5. Pad with = if less than 3 bytes

tools.base64EncoderDecoder.guide.encode.uses

  • Network transmission to avoid encoding issues
  • Embed resources in HTML/CSS
  • Transfer binary data via API interfaces

📥tools.base64EncoderDecoder.guide.decode.title

tools.base64EncoderDecoder.guide.decode.steps

  1. Remove trailing = padding
  2. Map characters back to indices (0-63)
  3. Recombine into continuous binary stream
  4. Split every 8 bits back to original bytes

tools.base64EncoderDecoder.guide.decode.uses

  • Restore files from API responses
  • Parse HTML embedded content
  • Restore network transmitted data
