to plain text handles both 20 and for spaces source result clear copy submit about the url decoder this tool reverses percent encoding paste a url a query string or any percent encoded text and it returns the original human readable value percent encoding replaces characters that aren t safe inside a url spaces non ascii letters with a followed by two hex digits so a space becomes 20 and café becomes caf c3 a9 this tool undoes exactly that 3d becomes 26 becomes and multi byte utf 8 sequences like c3 a9 reassemble back into é under the hood it runs two steps matching php s urldecode rather than the stricter rawurldecode first it replaces every literal with a space then it passes the result to the browser s built in decodeuricomponent which resolves the remaining xx sequences and decodes them as utf 8 the order matters a in a query string almost always means a space since that s how html forms encode one but a literal plus sign has to survive as 2b or this tool will turn it into a space too everything runs in your browser no input is sent to a server reach for this when a query string redirect url or webhook payload shows up percent encoded in a browser address bar a server log or an api response and you need to read the value inside it a search term an email address a callback target it doubles as a sanity check on your own encoding round trip a value through the url encoder and back and you should get the original text if this tool throws instead the input has a bare not followed by two hex digits usually a sign the text was never percent encoded a literal 50 off or was assembled with unsafe string concatenation examples decode a query string text input name 3djohn doe 26city 3dnew york output name john doe city new york 3d decodes to 26 decodes to and each becomes a space decode utf 8 percent encoded characters text input name jos c3 a9 city s c3 a3o paulo output name josé city são paulo c3 a9 and c3 a3 are the two byte utf 8 encodings of é and ã multi byte sequences reassemble correctly the equivalent one liner in javascript js function urldecode input return decodeuricomponent input replace g urldecode name 3djohn doe 26city 3dnew york name john doe city new york this is exactly what runs client side when you click submit php s own urldecode behaves the same way rawurldecode differs by leaving alone frequently asked questions why does a in my input turn into a space this tool matches php s urldecode convention where is shorthand for 20 coming from html form encoding application x www form urlencoded so both decode to a space if your text has a literal plus sign that must survive it needs to be percent encoded as 2b before you paste it in what s the difference between url decoding and base64 decoding url decoding reverses xx escapes used to make text safe inside a url or query string base64 decoding reverses a different encoding used to represent arbitrary binary data as ascii text such as in data uris or jwt segments it uses only letters digits and padding with no characters so use the base 64 decoder if that s what you re looking at is this the same as javascript s decodeuricomponent almost this tool runs decodeuricomponent but first converts every to a space which plain decodeuricomponent does not do both php s rawurldecode and javascript s bare decodeuricomponent leave untouched decoding only xx sequences why am i getting an error instead of a decoded result the input contains a that isn t followed by two valid hexadecimal digits which is invalid percent encoding and can t be decoded this usually means the text was never actually percent encoded a stray in plain text like 50 off or it was corrupted by double encoding or manual string editing does this tool send my text to a server no decoding runs entirely in your browser using javascript s built in decodeuricomponent the text you paste is never transmitted logged or stored related tools url encoder the inverse operation percent encode text for safe use in a url base 64 decoder a different encoding scheme common in tokens and data uris no characters involved html encoder encode or decode html entities instead a different
