Solid color generator

Create a solid color image in any size online. Choose a HEX, RGB, or HSL color, set the exact width and height, select a common aspect ratio, preview the result, and download it as PNG, JPG, or WebP.

Use the generator for plain color backgrounds, social media graphics, placeholders, test images, presentation backgrounds, and website or app assets. Presets cover 1:1, 3:2, 4:3, 4:5, 16:9, 9:16, and 21:9, while the ratio lock keeps custom dimensions in sync.

Everything is generated locally in your browser, so you can create and download a solid color image without installing design software, creating an account, or uploading a file.

FAQ

What ratios and sizes are supported?

Ratio presets include 1:1, 3:2, 4:3, 4:5, 16:9, 9:16, and 21:9 - each fills its recommended size with one click. Other common ratios like 5:4, 2:3, and 16:10 are detected automatically, and any custom width and height can be entered. Popular sizes for Instagram posts, Stories, YouTube thumbnails, Full HD, 4K, and Open Graph are also built in.

What does the ratio lock do?

Turn on the lock between width and height, and changing either side updates the other to keep the ratio - for example, at 16:9, changing the width to 1280 sets the height to 720 automatically.

What export formats are available?

PNG, JPG, and WebP export are supported.

Completely free with no sign-up. It runs locally in your browser with no uploads.

Why use this solid color generator?
