Which color formats are supported?

The tool supports inputting standard Hex colors and provides output in RGBA, Hex (#RRGGBBAA), and HSLA formats.

Can I process multiple colors at once?

Yes, use the 'Batch Colors' field to enter multiple Hex codes separated by commas to process them simultaneously.

How does the real-time preview work?

The tool renders your color against a customizable background color, allowing you to see exactly how the transparency will appear on your website or app.

What is the difference between Alpha and Percentage modes?

Alpha mode typically uses a 0.0 to 1.0 scale, while Percentage mode uses a 0% to 100% scale to define the transparency level.

Is the original color preserved?

Yes, you can toggle the 'Include Original Colors' option to compare your modified transparent colors against the original solid colors.
