URL Encoder / Decoder

Four tools in one: encode URLs with percent-encoding, decode encoded URLs, parse any URL into its components, and build URLs with a visual query parameter editor.

URL Encoding

Convert special characters to percent-encoded format for safe URL transmission. Characters like spaces become %20, ampersands become %26, etc. Essential for API calls, form submissions, and query parameters.

URL Decoding

Convert percent-encoded URLs back to their original format. Useful for debugging encoded URLs, processing webhook data, and analyzing request logs.

URL Parser

Break any URL into its components: protocol (http/https), hostname, port, pathname, search/query parameters, hash/fragment. Shows each component separately for easy analysis.

URL Builder

Visually construct URLs by adding query parameters. Add, edit, remove, and reorder parameters. The URL updates in real-time. Copy the generated URL for use in applications.

When to Use URL Encoding

API requests: Query parameters must be encoded if they contain special characters. Form submissions: HTML form data is automatically encoded when using GET. Link sharing: Ensure URLs work correctly when shared via email or messaging. Cookie values: Cookies often require URL encoding for special characters.
