any css stylesheet and either pretty print it with your chosen indent or shrink it to a single line everything runs in your browser your css never leaves the page beautify minify copy clear indent source result about the css beautifier and minifier this tool has two independent one click operations on the css you paste in beautify pretty prints it with consistent indentation one declaration per line and a space before each opening brace minify strips comments and collapses everything to the smallest whitespace it can safely remove both run entirely in your browser the css never leaves the page so pasting a work in progress stylesheet here doesn t send it anywhere beautify s indent width is configurable from 1 to 8 spaces minify has no options because it s a single predictable pass beautify calls prettier 3 s standalone build in the browser prettier standalone plus its postcss plugin the same parser prettier uses for css less and scss so the output matches what prettier produces from the command line or an editor plugin minify deliberately isn t prettier or a full minifier like clean css it s a regex pass minifycss that strips comments collapses whitespace runs to a single space and removes space around it skips selector merging and value shortening on purpose and special cases url data so base64 encoded images and inline svgs aren t corrupted by the whitespace pass reach for beautify when you have minified or inconsistently formatted css copied from browser devtools a bundler s output or a teammate s one line rule and need to read or diff it the indent field controls the output width reach for minify when you need to paste css into a style tag or a size constrained snippet without wiring up a build step if the source has a syntax error an unclosed brace a stray token beautify surfaces prettier s parse error e g csssyntaxerror unclosed block instead of guessing minify never throws since it only rewrites whitespace and comments examples beautify messy one line css to readable css card display flex padding 16px color 333333 card title font weight bold font size 14px beautify output indent 2 card display flex padding 16px color 333333 card title font weight bold font size 14px exact output of the beautify button at indent width 2 the default matches prettier s css printer one declaration per line a space before semicolons kept minify readable css to one line css card card container display flex padding 16px color 333333 card title font weight bold minify output card display flex padding 16px color 333333 card title font weight bold comments are stripped and whitespace collapses to one line but selectors aren t merged and values aren t shortened that s a deliberate limit not a bug minify data uris come out untouched css icon background url data image svg xml svg width 10 a svg minify output whitespace inside the data uri survives icon background url data image svg xml svg width 10 a svg the minifier detects url data swaps it for a placeholder before collapsing whitespace then restores it verbatim so a base64 image or inline svg is never corrupted even one with literal spaces or line breaks frequently asked questions does my css get uploaded anywhere when i use this tool no beautify runs prettier s standalone build and minify runs a local regex pass both entirely in your browser tab nothing you paste is sent to a server logged or stored closing the tab discards it does the css minifier merge selectors or shorten hex colors like a build tool minifier would no this minifier only strips comments and collapses whitespace and separators it doesn t merge duplicate selectors shorten ffffff to fff or touch values at all for maximum compression use a dedicated minifier like clean css in a build pipeline why did beautify show an error instead of formatting my css beautify parses your css with prettier before it can format it so invalid css an unclosed brace a stray character throws a parse error instead of being silently guessed at the message e g csssyntaxerror unclosed block includes a line and column number pointing at the problem will minifying break a background image written as url data or an inline svg no the minifier detects url data before collapsing whitespace sets it aside and splices it back in unchanged afterward so a base64 image or an inline svg with literal spaces or line breaks in its markup comes out exactly as it went in what indent size should i use for beautify 2 spaces is this tool s default and the most common convention in css style guides the field next to beautify accepts any whole number from 1 to 8 so change it before clicking beautify if your project uses a different indent size 4 spaces is the next most common related tools css code formatter same prettier css parser as beautify here as one of eight languages on the general formatter no minify button but supports more options less code formatter format less stylesheets with the same underlying prettier css parser scss code formatter format scss sass with the same underlying prettier css parser json beautifier same beautify minify pattern applied to json instead of css learn more lesson css syntax why
