FAQs
What is a placeholder image?
A placeholder image is a temporary image used during web design, development, or mockups to represent where a real image will eventually be placed. It typically shows the dimensions and helps visualize layout before final content is available.
What sizes can I generate?
You can create any custom size from 1×1 to 10,000×10,000 pixels. We also provide 20+ common presets including square sizes, banner sizes, ad sizes (leaderboard, skyscraper, etc.), standard image sizes (HD, widescreen), and social media sizes (Instagram, Facebook, Twitter).
Can I add custom text to the placeholder?
Yes! You can add any custom text you want. If you leave the text field empty, the placeholder will automatically display its dimensions (e.g., '400×300'). Long text automatically wraps to multiple lines.
What does the Auto Contrast button do?
The Auto Contrast button automatically selects either black or white text color based on your background color to ensure maximum readability. It calculates the relative luminance of the background and chooses the text color with the best contrast.
Which format should I use - PNG, JPEG, or WebP?
PNG is best for placeholders with solid colors and text (lossless, supports transparency). JPEG is good for smaller file sizes but uses lossy compression. WebP offers the best compression with good quality but may not be supported in older browsers. For most placeholders, PNG is recommended.
Can I use these placeholders commercially?
Yes! All generated placeholder images are free to use for any purpose including commercial projects, client work, websites, apps, mockups, and presentations. No attribution required.
What are common use cases for placeholder images?
Placeholder images are commonly used for: website mockups and wireframes, testing responsive layouts, development before final images are ready, design presentations, prototyping, blog post templates, and demonstrating image placement in documentation.
Is there a limit to how many placeholders I can generate?
No! You can generate unlimited placeholder images. All processing happens in your browser, so there are no server limits or quotas.
Can I generate multiple sizes at once?
Currently, you generate one size at a time. However, you can quickly switch between preset sizes and regenerate with the same colors and text settings. Each generation takes less than a second.
