URL Encoder / Decoder — Free Online Tool
About URL Encoder / Decoder
The URL Encoder / Decoder is a essential Developer Tool for anyone building web applications, handling API integrations, or debugging complex tracking links. URLs are restricted to the ASCII character set; any special characters or spaces must be percent-encoded to ensure they are transmitted accurately over the internet. This tool provides a high-performance interface for sanitizing query strings and decoding visually obscure %20-filled links back into readable plain text.
By using our encoder, you ensure that your GET requests remain valid and that your application's routing doesn't break when encountering non-standard characters in parameters.
Networking Features
- RFC 3986 Compliance: Adheres strictly to modern web standards for percent-encoding and component safety.
- Multi-Parameter Awareness: Correctly handles ampersands, equal signs, and slashes within complex query chains.
- Instant Translation: See your readable text transform into a valid URL-safe string in real-time.
Usage Guide
- Paste your intended URL parameter or encoded link into the input field.
- Select 'Encode' for safe transmission or 'Decode' to read the original parameter values.
- Export the result and verify your API endpoint or deep link functionality.
Pro Tip
Only encode the values of your query parameters, not the protocol (`https://`) or domain name, to ensure the URL remains resolvable by the browser.
