URL Decoder

URL Decoder is a tool that converts percent-encoded URL strings back into human-readable text. When URLs are encoded, characters like spaces, special symbols, and non-ASCII letters are replaced with a percent sign followed by a hexadecimal code — for example, a space becomes %20 and an ampersand becomes %26. This tool reverses that process, giving you the original, readable string in seconds.

For developers, this is an everyday necessity. Encoded URLs appear constantly in browser address bars, HTTP logs, API responses, authentication tokens, and form submissions. Trying to read or debug a URL like %2Fapi%2Fv1%2Fusers%3Fname%3DJohn%20Doe by eye is tedious and error-prone. A dedicated decoder removes that friction, letting you focus on what the data actually says rather than mentally parsing hex sequences.

Using the tool is straightforward: paste your percent-encoded URL or URL fragment into the input field and the decoded output appears immediately. You can decode a full URL, just a query string, or even an isolated value — the tool handles all three. The output is plain, readable text that you can copy and use directly in your work.

The tool correctly handles both standard percent-encoding (as defined by RFC 3986) and the application/x-www-form-urlencoded format, where the plus sign (+) is treated as a space. This matters because form-submitted data and query parameters often use + instead of %20, and decoding them incorrectly produces garbled output. If you see a + in your encoded string, this tool will handle it as expected.

One edge case to be aware of: if your input contains a percent sign that is not followed by valid hex digits (e.g., a literal % in corrupted data), the decoder will flag or skip the malformed sequence rather than crash silently. It is also worth noting that decoding is not always reversible without context — some decoded characters may need re-encoding before being safely embedded back into a URL.
