entities encode tags decode tags source reset result copy about the html entities encoder decoder html entities encoder decoder converts text between raw characters and html entity references in four modes encode entities decode entities encode tags and decode tags the two entity modes handle a wide character range every printable character from space through a large cjk block plus and turning each into its decimal numeric entity or back again the two tag modes only touch the eight characters that can break html markup the backtick and converting them to a mix of named and numeric entities and leaving everything else as is each mode is a single regular expression replace over the input there s no html parser or hidden dom element involved encodehtmlentities matches 香 g and rewrites every hit to plus its utf 16 code unit decodehtmlentities only reverses d decimal so it leaves hex and named entities untouched encodehtmltags decodehtmltags use a fixed lookup table for the eight tag characters instead because the range tested tops out at u 9999 characters beyond it most emoji and some rarer cjk hangul pass through encode entities unescaped the whole page runs client side nothing you paste is sent to a server use encode tags before dropping a code sample or user submitted markup into a pre code block so the browser renders it as visible text instead of parsing it as a real tag use encode entities when you need an ascii safe payload for something like an email template or csv export since it flattens accented and cjk characters to nnn too not just markup special ones match your decode mode to whichever encode mode produced the string decode entities won t touch the named or hex entities that encode tags outputs and you ll get partially decoded garbage instead of the original text examples escaping a script tag with encode tags text source script alert xss script result encode tags script alert xss script only the eight tag breaking characters change the letters in alert xss and script are untouched this is the form to use before dropping a code sample into a pre or code block encode entities converts every character not just markup text source p café 世界 p result encode entities p café 世界 p every character became a decimal entity including plain letters the accented é and the cjk characters not just and encode tags on the same input would leave café 世界 untouched and only escape the angle brackets and slash p café 世界 p decode entities can t reverse encode tags output text source result decode entities only matches the decimal pattern digits so it s the only one decoded back to the named entity and the hex entity pass through unchanged reverse those with decode tags instead frequently asked questions why do i need to encode html entities in the first place characters like and have special meaning in html so a browser parses a literal div inside a text string as a real tag rather than displaying the four characters div replacing them with entity references named or numeric tells the browser to render the literal character instead of treating it as markup what s the difference between encoding html entities and encoding html tags encode entities converts every character in a wide range plain letters accented characters cjk text plus angle brackets and ampersands into decimal numeric entities like encode tags only escapes the eight characters that can break html markup ampersand angle brackets quotes backtick equals sign and slash leaving normal text untouched and using named entities like where one exists why doesn t decode entities undo output from encode tags decode entities only reverses decimal numeric entities matching followed by digits and a semicolon such as encode tags produces a mix of named entities and hex entities neither of which match that pattern use decode tags to invert encode tags output and decode entities to invert encode entities output is it safe to paste sensitive html or source code into an online html encoder yes all four conversions encode entities decode entities encode tags and decode tags run as plain javascript string replacement in your browser tab there s no network request so pasted content is never uploaded anywhere does html entity encoding handle emoji and other unicode characters correctly this tool s encode entities mode covers characters from space up to u 9999 a boundary inside the cjk block so most emoji and some rarer cjk or hangul characters fall outside it and pass through unescaped rather than becoming numeric entities related tools html tags remover strips tags out entirely instead of escaping them use it when you want plain text not a displayable copy of the markup html formatter indents and beautifies raw html source useful before or after an encode decode pass on a full document url encoder percent encodes characters for safe use inside a url a different escaping context than html entities base 64 encoder another ascii safe encoding useful when encode entities longer nnn output isn t the format the destination expects learn more lesson html entities covers named decimal and hex character references in depth the exact three forms this tool encodes to and decodes from lesson html character sets background on ascii iso 8859 1 and utf 8 relevant if you re using encode entities to produce an ascii safe payload w3docs tutoriais
