Tips for Using Placeholder Images
- Use descriptive text that hints at the final content — this helps clients and team members visualize the layout.

Frequently Asked Questions — Placeholder Image Generator
Is the placeholder generator free?
Yes, completely free. No registration, no hidden charges, and no watermarks. All processing happens locally in your browser.
What sizes can I generate?
You can generate any size from 10×10 pixels up to 4000×4000 pixels. The tool validates your input to ensure the dimensions are within this range.
Can I add custom text to the placeholder?
Yes! You can add any text to appear centered on the placeholder image. By default, the text shows the image dimensions (e.g., '800 × 600'). You can customize it or leave it blank for a clean placeholder.
What image format is generated?
The tool generates PNG images. PNG is ideal for placeholders because it supports exact pixel dimensions, sharp text rendering, and is universally supported by all browsers and design tools.
Can I change the colors?
Absolutely. You can customize both the background color and text color using the built-in color pickers. The preview updates instantly so you can see how the colors look together.
How do I use placeholders in my HTML?
Upload the generated PNG to your project's assets folder, then use it like any image: <img src="assets/placeholder-800x600.png" width="800" height="600" alt="Placeholder">. For responsive designs, use CSS max-width: 100% to scale it down.
Is there a maximum file size limit?
The tool limits dimensions to 4000×4000 pixels (16 megapixels) to prevent browser memory issues. Most placeholder use cases are well within this range — 1920×1080, 800×600, and 400×300 are common web design sizes.
