Decode percent-encoded URLs, query parameters, and special characters back into human-readable text.
| Key | Decoded Value | Action |
|---|
When web browsers, reverse proxies, and API gateways process incoming web traffic, query strings containing non-ASCII symbols, spaces, and reserved characters are percent-encoded into hexadecimal byte streams. Decoding these strings is a daily task for web developers, cybersecurity analysts, and QA engineers inspecting tracking links, debugging OAuth authentication flows, or analyzing server request logs.
The Todoal URL Decoder instantly parses percent-encoded text (%20, %2F, %3F, %26) into clean, human-readable strings. Featuring a built-in Query Parameter Inspector, it automatically unpacks complex query arguments into key-value pairs with one-click individual value copying.
Automatically detects query substrings (?key=value&utm_source=...), splits parameters, and formats them into an interactive tabular breakdown for instant inspection and individual item copying.
Choose Component Mode (decodeURIComponent) to decode all symbols including slashes and question marks, or Full URL Mode (decodeURI) to preserve valid URI routing syntax.
In form submissions and search URLs (application/x-www-form-urlencoded), spaces are frequently encoded as plus signs (+). Component mode handles plus signs seamlessly so your decoded text reads naturally.
Decoding executes in your browser sandbox without network transmissions. Sensitive access tokens, session IDs, and internal API query routes remain strictly confidential.
| Percent Code | Decoded Character | Common Context & Meaning |
|---|---|---|
| %20 / + | [Space] | Whitespace separating query words or phrases. |
| %2F | / | Forward slash (path segment delimiter). |
| %3F | ? | Question mark (initiator of URL query string). |
| %26 | & | Ampersand (separator between distinct query key-value pairs). |
| %3D | = | Equals sign (assigns query value to parameter name). |
| %23 | # | Hash / Octothorpe (URL anchor or fragment identifier). |
Combine URL decoding with other foundational data processing tools. Re-encode parameters before initiating outbound API calls using the URL Encoder. For binary data payloads or basic auth credentials, decode strings with the Base64 Decoder or generate new base64 streams with the Base64 Encoder.
Convert encoded HTML entities in scraped web content using our HTML Decoder, clean unescaped string literals with the JSON Unescape Tool, and inspect JSON Web Tokens passed in URL queries using the JWT Decoder.
