CSS Box-Shadow Generator - Step By Step
CSS Box-Shadow Generator runs in three steps: open the tool, drag the sliders, then copy the result. This page walks through what each step does.
Step 1 - open the tool
Go to CSS Box-Shadow Generator. The preview box and a starter shadow render immediately - nothing needs to be installed or signed in first.
Step 2 - shape the shadow
Drag horizontal offset and vertical offset to move the shadow, blur radius to soften its edge, and spread radius to grow or shrink it. Pick a shadow color and opacity, and check Inset if you want an inner shadow instead of a drop shadow. The preview swatch updates on every change.
Step 3 - copy the result
Click Copy CSS to copy the generated box-shadow line to your clipboard, or select the text in the output box manually. Everything happens in your browser tab; nothing is uploaded.
Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
