Frequently Asked Questions

Yes — copy the data URL and use it as the src attribute of an <img> tag. No file is needed. Note that large images will produce very long data URLs, so for images above a few hundred pixels it's better to download and serve as a file.
OG Image refers to the Open Graph image — the image shown when a URL is shared on social media platforms like Twitter, Facebook, and LinkedIn. The standard recommended size is 1200×628 pixels.
The maximum is 2000×2000 pixels in this tool. Very large canvas sizes may use significant browser memory. For images above 1920×1080, the download PNG option is recommended over the data URL, as it will be an extremely long string.
Yes — use the Custom Label field to show any text on the placeholder (e.g. "Hero Image", "Profile Photo", "Product Shot"). Leave it blank to show the dimensions automatically.

About Image Placeholder Generator

Image Placeholder Generator creates placeholder images for mockups, wireframes, and development. Set any dimensions, background color, text color, and label text — the placeholder image downloads instantly, all in your browser.

How to Use

  1. Enter the Width and Height in pixels.
  2. Choose a Background Color and Text Color.
  3. Optionally customize the Label Text (defaults to the dimensions).
  4. Click Generate — the placeholder renders in the preview.
  5. Click Download PNG to save the image.

How It Works

The image is drawn on an HTML canvas at the specified dimensions with a colored rectangle and centered text label. The canvas is exported as a PNG — no server upload, no external service required.

Example

Generate a 1200×630 placeholder for an og:image preview. Use the label "Open Graph Image" to identify it in your mockup. Download and drop it directly into your design file.

Frequently Asked Questions

There is no hard limit set by the tool, but very large canvases (e.g. 10,000×10,000px) may be slow to render or exceed browser memory limits. For most placeholder needs, anything under 4000×4000px works fine.
Yes. Specify dimensions in pixels at your target DPI. For print at 300 DPI, a 4×6 inch image needs 1200×1800px. Download as PNG and use in your print layout.
This tool generates downloadable PNG files. For URL-based placeholders (like img src="https://..."), services like via.placeholder.com or placehold.co provide hot-linkable images for development.
No. The entire image is generated using the HTML canvas API in your browser. Nothing is uploaded or transmitted anywhere.
