Frequently Asked Questions

Can I create inset shadows?

Yes. Alongside standard drop shadows, you can toggle inset to create inner shadows, and layer multiple shadows for more complex depth effects.

What do blur and spread control?

Blur softens the shadow's edge, while spread grows or shrinks the shadow's size before blurring. Adjusting both with the live preview lets you match any design quickly.

Is CSS Box Shadow Generator free to use?

Yes. CSS Box Shadow Generator is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use CSS Box Shadow Generator?

Absolutely. CSS Box Shadow Generator runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
