Frequently Asked Questions
What does this tool do?
This tool replaces transparent areas in WEBP images with a solid color background of your choice. Perfect for converting transparent PNGs/WEBP to images with white, black, or any colored background.
Is my image uploaded to a server?
No. All processing happens entirely in your browser using JavaScript and the Canvas API. Your image never leaves your device, ensuring complete privacy and security.
Is this tool free?
Yes, completely free with no registration, no watermarks, and no usage limits. Use it as many times as you need for personal or commercial projects.
What if my WEBP doesn’t have transparency?
The tool will still work, but you won’t see any visible change since opaque pixels aren’t affected. The background color only shows through transparent areas.
Can I use custom colors beyond the picker?
Yes! The color picker supports all RGB colors. You can also manually type hex codes, RGB values, or named colors if your browser supports that in the color input.
What’s the maximum file size supported?
The tool accepts WEBP images up to 10MB. Most images under 4000×4000 pixels process instantly. Larger images may take a moment depending on your device.
Does it preserve image quality?
Yes. The tool outputs WEBP at maximum quality (100%). The only change is the background color – all other pixels remain unchanged.
Can I add gradients or patterns?
Currently, the tool only supports solid color backgrounds. For gradients or patterns, you would need dedicated image editing software.
Can I use this tool offline?
Yes. Once the page loads, all processing happens locally in your browser with JavaScript. No internet connection is required for the actual image processing.
Which browsers are supported?
All modern browsers with WEBP and Canvas API support work perfectly: Chrome 23+, Firefox 65+, Safari 14+, and Edge 18+.
