URL Encoder & Decoder

Convert standard string characters and whole website addresses into safe, portable percent-encoded string figures, or decode them back to plain text. Safely toggles between standard query-parameter rules or complete URI rules with integrated malformed error detection.

How to Encode & Decode URLs

  1. Select URL percent-encoding or decoding parameters.
  2. Paste your routing query strings, paths, or full URLs into the dashboard.
  3. Copy the output with special escape sequences or clean characters restored.

Key Features

  • Component vs Full URL Mode: Flexible encoding patterns for safe queries.
  • Unicode Code Points preservation: Decodes native accents and international characters.
  • Mass Input Processing: Instantly translates paths with complex symbol patterns.

Common Use Cases

  • Format complex analytical tracker logs with nested query offsets.
  • Repair broken/unreadable URL query parameters containing multiple brackets.
  • Develop clean and predictable API request variables for web clients.

Frequently Asked Questions

What is Percent Encoding or URL encoding?

Percent encoding transforms non-ASCII characters, spaces, and secure characters (such as "&", "=", "?") into percent signs followed by two hexadecimal digits (e.g., space becomes %20), enabling secure delivery via standard HTTP protocols.

When should I choose "encodeURIComponent" vs "encodeURI"?

Use "encodeURIComponent" (Query parameters) for single parameter values (keys, tokens, names) to escape all special structures. Choose "encodeURI" (Complete URLs) only when you have a full address (e.g., https://example.com/search) and want to keep structural slashes and colons readable.

What causes a Malformed URI Error on URL Decoding?

This happens if a percentage sign (%) occurs in the input without exactly two hexadecimal characters following it (e.g., "%2G" or a % sitting at the end of the input). We catch these gracefully and provide troubleshooting tips.
