About URL Encoding/Decoding

URL encoding converts characters into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

Commonly encoded characters include:

  • Space → %20
  • ! → %21
  • # → %23
  • $ → %24
  • % → %25
  • & → %26
  • ' → %27
  • + → %2B
  • , → %2C
  • / → %2F
  • : → %3A
  • ; → %3B
  • = → %3D
  • ? → %3F
  • @ → %40

URL decoding is the reverse process that converts encoded characters back to their original form.
