About URL Encoder / Decoder

OptiPix URL Encoder/Decoder converts text between human-readable and percent-encoded URL formats. Use encodeURIComponent (default), encodeURI, or full percent-encoding modes. Toggle live mode to auto-convert as you type. The built-in URL parser breaks any URL into its components — protocol, host, port, path, query parameters, and fragment — making it easy to inspect and debug URLs. Copy encoded or decoded text with one click. Perfect for web developers working with query strings, API integrations, and URL debugging. Everything runs in your browser — no data is sent to any server.

How It Works

The tool uses JavaScript's built-in encodeURIComponent(), encodeURI(), and decodeURIComponent() functions for standard encoding/decoding. The URL parser uses the URL constructor to decompose URLs into their RFC 3986 components.

Use Cases

  • •Encode query parameters for API requests
  • •Decode percent-encoded URLs for debugging
  • •Parse complex URLs to inspect individual components
  • •Prepare text for safe inclusion in URL paths
  • •Debug URL query strings with special characters

Frequently Asked Questions

What is URL encoding?
URL encoding (percent-encoding) replaces unsafe characters with a % followed by their hexadecimal value. For example, a space becomes %20 and an ampersand becomes %26.
What encoding modes are available?
Three modes: encodeURIComponent (encodes everything except A-Z, a-z, 0-9, and a few safe characters), encodeURI (preserves URL structure characters like ://?#), and full percent-encoding (encodes absolutely everything).
Can I parse a URL into its components?
Yes. Paste any URL and the parser will break it into protocol, host, port, path, query string, fragment, and individual query parameters.
Is my data sent to any server?
No. All encoding, decoding, and parsing happens locally in your browser using built-in JavaScript functions.
Does it handle international characters?
Yes. The encoder properly handles Unicode characters, emoji, and any UTF-8 text by encoding them as percent-encoded byte sequences.
