How to Use the Placeholder Image Generator
A placeholder image generator fills image slots in your layouts with dummy visuals before real content is ready. Every developer needs them — this tool creates them locally in your browser, instantly, at any size.
Step 1: Set the Dimensions
Choose a preset from the dropdown for common web formats (social media OG images at 1200×630, banner ads at 728×90, thumbnails at 150×150), or enter custom width and height values in pixels. Sizes up to 4000×4000 are supported. The preview updates live as you type.
Step 2: Customize Colors and Text
Set the background and text colors using the color pickers or enter hex values directly. The default gray on gray is the placeholder.com convention, but any color combination works. Use "Randomize Colors" to quickly explore options. Optionally add grid lines (useful for layout reference) or rounded corners (for rounded image containers).
Step 3: Choose Your Format
PNG for most uses (lossless, small for simple graphics), JPEG for photos or when file size matters, SVG for scalable placeholders that work at any resolution (ideal for responsive layouts), or WebP for modern browsers with the best compression ratio. The download uses the selected format.
Step 4: Export
Click "Download Image" to save the file directly. Use "Copy Data URI" to embed the image as base64 directly in HTML or CSS without a file request. "Copy IMG Tag" gives you a complete <img> element ready to paste into your markup. For multiple sizes, use Batch Mode to generate all at once.
FAQ
Is the placeholder image generator free?
Yes, completely free with no account or signup needed. Generate and download as many placeholder images as you need.
What image formats can I export?
Four formats: PNG (lossless, transparent support), JPEG (smaller file size, solid backgrounds), SVG (scalable vector, tiny file size), and WebP (modern format, best compression). PNG is best for most web development use cases.
What size can I make placeholder images?
Any size from 1x1 to 4000x4000 pixels. Use the size presets for common web formats (social media, banners, thumbnails) or enter exact custom dimensions.
Can I add custom text to the placeholder?
Yes. By default the image shows its dimensions (e.g., '600x400'). You can customize the text to any label, hide it entirely, or override with any string.
What is the difference between PNG and WebP?
WebP is Google's modern image format that produces files 25-34% smaller than PNG with similar quality. It is supported by all modern browsers. Use WebP for production images and PNG for compatibility with older tools or design software.
Can I generate multiple placeholder sizes at once?
Yes. Use batch mode to select common sizes from checkboxes and generate all of them at once. Each image downloads individually.
How do I embed a placeholder image directly in HTML?
Click 'Copy Data URI' to get the image as a base64 data URI string, then use it as the src attribute in an img tag: <img src="data:image/png;base64,...">. Or use 'Copy IMG Tag' to get the full tag ready to paste.
