URL Encoder & Decoder — Percent Encode & Decode URLs
About This Tool
URL Encoding (Percent-Encoding) converts query strings and addresses into compliant ASCII formatting for safe transmission over HTTP requests. This tool supports standard URI encoding (keeps domain, path delimiters, and query keys intact) and Component encoding (encodes all delimiters for secure nesting inside parameters).
How to Use
- Choose the active operation: either "Encode" or "Decode" mode.
- Enter or paste your target URL or parameter string in the input field.
- Select the target encoding scope: "Component" (encodes everything) or "Full URL" (keeps protocols like http:// safe).
- Review any decoding validation errors in real-time if parameters are malformed.
- Instantly copy the result output using the copy button.
