Frequently Asked Questions

What image formats can I generate?

You can export placeholder images as PNG (with transparency support), JPEG (smaller file sizes), or WebP (modern format with best compression). PNG is best for graphics with transparency, JPEG for photographs, and WebP for modern web projects prioritizing performance.

What's the maximum image size I can create?

You can generate images up to 4000x4000 pixels (16 megapixels). This covers virtually all web and print needs including large banners, hero images, and high-DPI displays. For extremely large images, consider using SVG placeholders instead to save bandwidth.

Can I use these images in commercial projects?

Absolutely! All generated placeholder images are yours to use freely in any project—personal or commercial—without attribution. They're simple geometric images created by you with our tool, so there are no copyright or licensing restrictions.

How do I create placeholder images with transparency?

Select PNG as the export format and choose a background color with opacity controls. You can create semi-transparent backgrounds or use fully transparent areas, perfect for overlaying on different backgrounds in your designs.

What are data URLs and when should I use them?

Data URLs embed images directly in HTML/CSS as base64-encoded strings (e.g., data:image/png;base64,...). They're perfect for small placeholders since they eliminate HTTP requests, but increase HTML/CSS file size. Best for inline SVG icons and small graphics under 10KB.

Can I add patterns or textures to placeholders?

Yes! Choose from diagonal stripes, grids, dots, or crosshatch patterns to make placeholder areas visually distinct. This helps differentiate placeholder content from actual content during development and design reviews.

How do preset dimensions work?

We include common image sizes for social media (1200x630 for Facebook, 1080x1080 for Instagram), web design (1920x1080 full HD, 800x600 standard), and more. Click any preset to instantly set those dimensions—saves time for common use cases.

Are these images optimized for web use?

Yes! Generated images use Canvas API which creates efficiently-encoded graphics. For web use, choose JPEG (smallest file size) or WebP (best quality-to-size ratio). The tool creates minimal file sizes since placeholders are simple geometric shapes and text.
