Button Forge is a free CSS button generator that runs in your browser with no install. Adjust padding, text, color, border, shadow, hover, and animation in the edit panel on the left, and the preview in the center updates instantly.
The HTML, CSS, and JS are generated in the panels on the right and can be pasted as is with the copy button. Drag any panel to move it, and use the dock at the bottom to toggle panels and reset.
