URL Encoder / Decoder
NewPercent-encode and decode URL components or query strings to avoid broken links and debugging mistakes.
A URL encoder and decoder prevents broken query strings and helps developers debug malformed links. Developers often need to percent-encode reserved characters to safely transmit data in HTTP requests.
This tool encodes and decodes either a single URL component (encodeURIComponent) or an entire query-like string (encoding keys and values). It includes validation feedback for invalid percent sequences.
All operations happen locally in your browser. Your data never leaves your browser.
