URL Encoder Online — Percent-Encode Query Strings & Special Characters

Online URL encoder. Escape spaces, slashes, ampersands, and unicode characters for safe use in HTTP GET query parameters and API endpoints.

✓ Safely escapes reserved characters (&, ?, =, /, #, spaces)

✓ Generates standards-compliant percent-encoded strings for GET requests

✓ Full UTF-8 support for emojis and international characters

✓ Prevents URL injection and query parameter splitting bugs

How It Works

  1. Type or paste your text or URL parameters.
  2. Characters outside the unreserved RFC 3986 set are converted to %XX hex codes.
  3. Copy the safe encoded string for your API request.
