FAQ
What is a placeholder image used for?+

Placeholder images are used during website and app development to fill in image slots before real content is available. They help designers and developers visualize layouts, test responsive behavior, and share mockups with clients without needing final assets.

Can I set a custom label on the placeholder image?+

Yes. You can type any text as the label — a description, a component name, or anything else. If you leave the label empty, the tool automatically uses the image dimensions (e.g. 800 × 600) as the label, which is the most common use case.

Which file format should I choose — PNG, JPEG, or WebP?+

Use PNG for lossless quality and transparency support. Choose JPEG for smaller file sizes when image quality is less critical. WebP offers the best balance of quality and file size for modern browsers but may not be supported in older tools.

Is there a size limit for generated images?+

The tool supports dimensions up to 4000 × 4000 px. Rendering happens entirely in your browser using the HTML Canvas API, so no data is sent to any server. Very large images may take a moment to render depending on your device.
