Paste any percent-encoded URL or string below to instantly decode it back into readable, shareable text.
URL decoding reverses percent-encoding, converting sequences like %20 and %3A back into their original readable characters (a space and a colon, in this example). It's the natural counterpart to URL encoding, and it's most often needed when reading log files, debugging tracking links, or inspecting query parameters shared by someone else.
Browsers decode most URLs automatically when displaying them, but raw server logs, exported reports, and API payloads often show the fully encoded version — this tool converts it back instantly.
Decoding fails when the input contains an incomplete or invalid percent-encoded sequence (for example, a stray '%' not followed by two valid hex characters). This usually means the original string was truncated or corrupted somewhere along the way.
Yes. Paste the full URL and it will decode all percent-encoded sequences throughout the string, including the path and query parameters.
Yes, when done correctly. Encoding and decoding a string in sequence should return you to the original text, assuming no data was lost or altered in between.
Yes. Percent-encoding is commonly used to represent non-ASCII characters (like accented letters or non-Latin scripts) as UTF-8 byte sequences, and this tool decodes those correctly back to their original characters.
