decoder decode a hex encoded string e g 48656c6c6f back to its utf 8 text representation source result clear copy submit about the hex to text decoder this tool decodes a hex encoded string back into readable text feed it a run of hexadecimal digits for example 48656c6c6f and it reads them two characters at a time converts each pair into the byte it represents and reassembles the original text hello in that example it s the inverse of hex encoding text into a 48656c6c6f style string which is what a tool like the binary to hex converter produces everything runs client side in the browser nothing you paste is sent to a server the transform trims leading and trailing whitespace checks that what s left has an even number of characters and consists only of 0 9 a f and a f then converts each two character pair into a byte with parseint pair 16 the resulting bytes are decoded as utf 8 with the browser s built in textdecoder so multi byte characters accented letters emoji reconstruct correctly instead of turning into mangled output you ll reach for this when inspecting a hex dump from a debugger or packet capture decoding a value a database or log stored as hex or checking the output of php s hex2bin whose behavior this tool mirrors this js port throws on invalid input instead of returning false it s also useful for verifying a bin2hex round trip or just reading what a hex string actually spells out without writing a throwaway script examples decode a hex string to text text input 48656c6c6f output hello each two digit hex pair decodes to one byte 48 h 65 e 6c l 6c l 6f o multi byte utf 8 characters text input 636166c3a9 output café é is two bytes in utf 8 c3 a9 so it takes four hex digits the decoder reads bytes not one hex pair per visible character the same operation in php php hex 48656c6c6f echo hex2bin hex hello var_dump hex2bin xyz bool false odd length input this tool is a js port of php s hex2bin same byte pairing logic but it throws a js error on invalid input instead of returning false frequently asked questions what does hex2bin do hex2bin is a php function that converts a string of hexadecimal digits back into the raw bytes it represents the reverse of bin2hex this tool runs the same logic in the browser paste in 48656c6c6f and you get hello back decoded as utf 8 text why am i getting an invalid hex input error the decoder requires the input after trimming outer whitespace to have an even number of characters and contain only 0 9 a f or a f an odd length string or any character outside that set throws this error instead of producing a wrong result can i decode hex with spaces between the bytes like 48 65 6c not directly only leading and trailing whitespace is trimmed so spaces between byte pairs trigger the invalid hex input error strip the internal spaces first input replace s g in javascript so you re left with one continuous run of hex digits is this the same as converting hex to binary digits 0s and 1s no despite the url s legacy bin naming this tool decodes hex into utf 8 text php s hex2bin behavior not into a string of 0 1 bits for bit level binary output use the string to binary converter instead does this tool send my input to a server no decoding happens entirely in your browser using javascript s built in textdecoder nothing you paste is transmitted logged or stored related tools binary to hex converter the inverse operation encode text into a hex string base 64 decoder decode base 64 back to text instead of hex number base converter convert a hex number like ff to decimal or another base not for decoding hex encoded text string to binary converter view a string s bytes as 0 1 binary digits instead of hex learn more lesson php hex2bin the php function this tool s decoding logic
