URL Encoder Decoder — encode and decode URLs and URL components instantly inside your browser, with no server required and no data sent anywhere. Whenever you work with web addresses, query strings, or form data, you run into percent-encoded characters like %20, %26, %3D. The url encoder decoder handles all of it: encode a raw string to a safe URL format, or decode a percent-encoded value back to readable text. Everything happens locally, offline, in one click. HOW TO USE THE URL ENCODER DECODER Click the toolbar icon to open the popup. Two tabs appear at the top: Encode and Decode. On the Encode tab you can choose between two modes: • Encode URL component — uses encodeURIComponent, which escapes all characters except letters, digits, and _ - . ~ This is the correct mode for encoding query parameter values or path segments. • Encode full URL — uses encodeURI, which preserves the structure characters like :, /, ?, #, &, = that make a URL valid. Use this mode when you have a complete URL that contains non-ASCII characters. Type or paste your input, click Encode, and the url encoder decoder shows the result instantly in the read-only output area. Click Copy to send it to the clipboard, or Clear to start over. On the Decode tab, paste any percent-encoded string. The url encoder decoder first tries decodeURIComponent, and if that fails due to malformed sequences it falls back to decodeURI, returning a meaningful error message for genuinely invalid input instead of throwing silently. The popup uses a dark theme that is easy on the eyes during long coding sessions, and all interactions are keyboard-friendly: press Ctrl+Enter in any textarea to trigger the operation without reaching for the mouse. WHY YOU NEED A URL ENCODER DECODER IN YOUR BROWSER Developers who build or test APIs constantly paste URLs into address bars, Postman, curl commands, or log files. A url encoder decoder right in the toolbar saves the round-trip to a website and works offline in any network environment. QA engineers use a url encoder decoder to verify that their test harnesses are generating correct percent-encoding for special characters, whitespace, Unicode, and reserved symbols. Getting encoding wrong is a common source of 400 Bad Request errors. Security researchers use a url encoder decoder to analyse suspicious links, decode obfuscated query parameters, or prepare payloads for testing. Because the url encoder decoder runs entirely locally, there is no risk of leaking test data to a third-party service. Frontend developers use a url encoder decoder to build query strings by hand, decode the output of fetch responses, or inspect encoded values in OAuth redirect URIs and JWT tokens embedded in URLs. Content editors who manage CMS platforms, redirect rules, or canonical URLs reach for a url encoder decoder to fix encoding issues in slugs and parameters without leaving the browser tab they are working in. WHAT MAKES THIS URL ENCODER DECODER DIFFERENT Offline and private — the url encoder decoder runs entirely inside the Chrome extension sandbox. Your URLs, API keys, tokens, and query strings never leave your device. There is no telemetry, no analytics, no cloud processing. Dual mode encoding — most tools encode everything or nothing. The url encoder decoder gives you explicit control: component mode for parameter values, full-URL mode for complete addresses with structure intact. Graceful error handling — invalid percent sequences return a clear error message rather than crashing. The url encoder decoder never breaks silently. Zero permissions — the url encoder decoder requests no browser permissions whatsoever. It cannot see your tabs, your history, or any page content. It only runs a popup. Dark theme UI — designed for developers who spend long hours coding, the url encoder decoder uses a dark colour scheme that reduces eye strain. TECHNICAL DETAILS Manifest Version 3. Pure JavaScript, no dependencies. The url encoder decoder uses the native browser encodeURI, encodeURIComponent, decodeURI, and decodeURIComponent functions — the same functions your web pages use — so the output is always spec-compliant. Available in 33 languages including English, Russian, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Turkish, Ukrainian, Japanese, Korean, Chinese, Hindi, Arabic, and more.
