Frequently Asked Questions

What is a placeholder image?

A placeholder image is a temporary image used in web design and development to represent where a real image will go. It typically shows the dimensions and is useful for wireframes, mockups, and layout testing.

What is the maximum image size?

You can generate images up to 4096x4096 pixels. For very large images, the generation may take a moment depending on your device's performance.

Can I use the Data URL directly in HTML?

Yes. A Data URL (base64-encoded image) can be used directly in an <img> src attribute or as a CSS background-image. It eliminates the need for a separate image file.

Is the image generated on a server?

No. The image is generated entirely in your browser using the Canvas API. No data is sent to any server, and the image exists only on your device.
