FAQ

1. What is a placeholder image and when should I use one?

A placeholder image is a temporary dummy image used during the design or development phase of a website or app. It helps you visualize layout and spacing before the real assets are ready — commonly used in wireframes, mockups, and prototypes.

2. What image formats can I download?

You can download your placeholder image as PNG for lossless quality, JPEG for smaller file sizes, or WebP for the best balance of quality and compression for modern browsers.

3. Can I generate placeholder images for social media?

Yes. The Presets mode includes ready-made dimensions for the most common social media formats: Instagram Post (1080×1080), Instagram Story (1080×1920), Twitter Header (1500×500), and Open Graph (1200×628).

4. Is there a maximum image size I can generate?

The tool supports dimensions up to 4000×4000 pixels. All rendering is handled by your browser's HTML5 Canvas, so performance depends on your device.

5. Does this tool store or upload my images?

No. Every placeholder image is generated entirely within your browser using the HTML5 Canvas API. Nothing is sent to any server — your images are created and downloaded locally.

Note: This Placeholder Image Generator is intended for design, development, and prototyping purposes. All image generation is performed client-side in your browser — no data is collected or stored.
