Image Placeholder Generator
Generate custom placeholder images with configurable size, colors, text, and format. Download or copy as data URI.
About This Tool
The Image Placeholder Generator is a free browser-based tool that creates placeholder images for web design, wireframing, prototyping, and development workflows. Instead of relying on external placeholder services that may go offline or add latency, you can generate exactly the image you need in seconds and download it directly.
All processing happens entirely in your browser using the Canvas API and SVG generation. No data is sent to any server, and no image is uploaded or stored anywhere. Your designs stay private on your machine.
You can configure every aspect of the generated image. Set custom width and height up to 4096 pixels, choose background and text colors to match your brand or design system, add custom text labels, and adjust the font size. The tool includes preset sizes for common use cases like OG images (1200×630), avatars (150×150), HD screens (1920×1080), and ad banners (300×250).
Output is available in three formats. PNG provides lossless quality and transparency support, ideal for most web use cases. JPEG offers smaller file sizes for photo-like placeholders. SVG produces scalable vector output that stays crisp at any size, perfect for responsive layouts and high-DPI displays.
The border radius option lets you create rounded or circular placeholder images without additional CSS. Combined with the Color Converter for precise color selection and the Image Resizer for adjusting existing images, this tool fits naturally into any front-end development workflow.
You can also copy the generated image as a data URI for embedding directly in HTML, CSS, or JavaScript without needing a separate file. This is particularly useful for prototyping and inline styling.
How to Use
- Select a preset size from the dropdown (Avatar, OG Image, HD, etc.) or enter custom width and height values.
- Pick a background color and text color using the color pickers or by typing hex values.
- Optionally enter custom text to display on the image. If left blank, the dimensions (e.g., "800×600") are shown automatically.
- Adjust the font size slider to control text size, and set the border radius for rounded corners.
- Select the output format: PNG, JPEG, or SVG.
- Click Download to save the image file, or click Copy Data URI to copy an inline data URI to your clipboard.
- Use Ctrl+Enter to download or Ctrl+Shift+C to copy the data URI.

FAQ
Is my data safe?
Yes. All image generation happens entirely in your browser using the HTML Canvas API and SVG string generation. No data is sent to any server, and no images are stored or logged. You can verify this by checking your browser's network tab while using the tool.
What is the maximum image size I can generate?
The tool supports dimensions up to 4096×4096 pixels. Very large images may take slightly longer to generate depending on your device's processing power, but the output quality is not affected.
What format should I use for placeholder images?
PNG is the best default choice for web placeholders — it supports transparency and provides crisp text. Use JPEG if file size matters more than text clarity. Choose SVG for placeholders that need to scale to any size without losing quality, such as responsive layouts.
Can I use the generated images in production?
Absolutely. The generated images are standard PNG, JPEG, or SVG files with no restrictions. You can use them in websites, apps, presentations, documentation, or anywhere else you need a placeholder image.
How does the data URI option work?
Clicking 'Copy Data URI' generates a base64-encoded string representation of the image that you can paste directly into HTML img src attributes, CSS background-image properties, or JavaScript code. This embeds the image inline without requiring a separate file.
Why does my text get cut off on narrow images?
The Canvas API limits text rendering to 90% of the image width to prevent overflow. If your custom text is too long for the image dimensions, reduce the font size or shorten the text. Alternatively, increase the image width.
