Placeholder Image Generator
Generate placeholder images in SVG, PNG, or JPEG for mockups and prototypes.
What is the Placeholder Image Generator?
The Placeholder Image Generator creates blank placeholder images in SVG, PNG, or JPEG with custom dimensions, colors, and text. It is built for filling layouts during design and development before final assets are ready.
Mockups and prototypes often need stand-in images at specific sizes. This tool generates one to your exact width and height, shows a live preview, and lets you download the file or copy it as a data URL or an HTML img tag.
It is free and runs entirely in your browser with no signup. Images are rendered client-side using SVG and the canvas API, so nothing is uploaded to a server.
How to use the Placeholder Image Generator
- 1Enter the width and height in pixels for the placeholder image.
- 2Optionally type custom text, or leave it blank to display the dimensions automatically.
- 3Choose the background and text colors with the color pickers or hex fields.
- 4Select the output format: SVG, PNG, or JPEG.
- 5Use the live preview to check the result, then download the image or copy it as a data URL or HTML tag.

- Filling image slots in a wireframe or mockup before real photos are available.
- Generating sized placeholders to test responsive image layouts and grids.
- Creating a quick data URL image for a demo without hosting a file.
- Producing labeled placeholders that show their dimensions during development.
- Building example assets for documentation or component library stories.

Frequently asked questions
How do I generate a placeholder image?
Enter the width and height, choose your colors and format, and optionally add custom text. The preview updates instantly, and you can then download the image or copy it as a data URL or HTML tag.
Is the Placeholder Image Generator free?
Yes, it is free with no signup. Images are generated in your browser, so there are no limits and no files are uploaded anywhere.
What image formats can I export?
You can export the placeholder as an SVG vector file, or as a PNG or JPEG raster image. SVG stays sharp at any size, while PNG and JPEG are fixed-resolution bitmaps.
What is a data URL and when should I use it?
A data URL embeds the image directly in your code as a text string, so no separate file is needed. It is handy for quick demos and prototypes, but for production use a hosted image file is usually better.
Can I add custom text to the placeholder?
Yes. Type any text into the Custom Text field and it is centered on the image. If you leave it empty, the tool shows the image dimensions, for example 800x600.
Are my placeholder images uploaded to a server?
No. SVG output is built as text and PNG or JPEG output is drawn with the browser canvas API. Everything happens locally, so nothing is sent to a server.
