About Gradient Builder

Gradient Builder on FileToolsHub creates linear or radial CSS gradients with a live preview. Add up to six color stops, set the angle, copy the background rule, or download a PNG preview for docs and social cards.

Unlike a one-line text stub, this tool is interactive: edit stops, see the result immediately, and export without uploading files. Processing stays on your device.

Start from Color Picker to choose stop colors, then open Gradient Builder to assemble the CSS. Related CSS helpers (css-gradient-generator, opacity calculator) sit in the same text category for finer tweaks.

Use /tool/gradient-generator when you need a production-ready background snippet for landing pages, buttons, or hero sections — free and unlimited on FileToolsHub.
