What is an SVG Placeholder Generator?

An SVG Placeholder Generator is a tool that creates customizable SVG placeholder images for use in web development, design mockups, and prototyping. Instead of downloading or creating placeholder images manually, you can generate them instantly with custom dimensions, colors, and text directly in your browser.

Our online SVG Placeholder Generator lets you create professional-looking placeholder images with a live preview. You can customize every aspect including the width, height, background color, text color, font size, and the label text. The generated SVG can be copied as code, as a Base64 data URI, or downloaded as an SVG file for use in your projects.

How to Use the SVG Placeholder Generator

  1. Set dimensions — Enter the desired width and height for your placeholder image.
  2. Choose colors — Select background and text colors using the color pickers.
  3. Adjust font size — Set the font size for the label text.
  4. Enter custom text — Optionally enter custom label text or leave empty to show dimensions.
  5. Toggle exact size — Choose whether to set explicit width/height attributes on the SVG tag.
  6. Copy or download — Copy the SVG code, copy the Base64 data URI, or download the SVG file.

Common Use Cases

  • Web development — Use placeholder images during development before final assets are ready.
  • Design mockups — Create placeholders for wireframes and prototypes with custom dimensions.
  • Documentation — Generate consistent placeholder images for technical documentation and tutorials.
  • Testing — Create images of specific sizes for responsive design testing and layout validation.
  • Blog posts — Generate custom-sized placeholder images for blog post featured images and thumbnails.

Features

  • Custom dimensions — Set any width and height for your placeholder.
  • Color customization — Choose any background and text color using color pickers.
  • Live preview — See your placeholder update instantly as you adjust settings.
  • Custom text — Add your own label or auto-generate a WxH size label.
  • Multiple output formats — Copy as raw SVG code or Base64 data URI.
  • File download — Download the SVG file for offline use.
  • Client-side processing — Everything runs in your browser with no server uploads.

After generating your SVG placeholder, view it in the SVG Viewer, convert it to a data URI with Image to Base64, or create matching colors with the Color Palette Generator.

Frequently Asked Questions

What is an SVG placeholder?

An SVG placeholder is a scalable vector graphic used as a temporary stand-in for final images during web development and design. It displays the dimensions and helps visualize the layout before the actual images are ready. SVG placeholders are resolution-independent and can be scaled to any size without losing quality.

How do I use the generated SVG in my HTML code?

You can use the SVG code in three ways: embed the raw SVG code directly in your HTML, use the Base64 data URI as an image source like <img src="data:image/svg+xml;base64,...">, or download the SVG file and reference it with <img src="placeholder.svg">. The most common approach for development is to embed the SVG inline for full control over styling.

Can I customize the text displayed on the placeholder?

Yes, you can enter any custom text to display on the placeholder. If you leave the custom text field empty, the tool will automatically display the dimensions in the format WxH (for example, 600x350). This is helpful for quickly identifying placeholder sizes during development.

What is the difference between using width/height attributes and viewBox?

When the exact size option is enabled, the SVG includes explicit width and height attributes, setting a fixed display size. When disabled, only the viewBox is used, making the SVG scale to fit its container. Using explicit dimensions is better for placeholders that need precise sizing, while viewBox-only is suitable for responsive layouts.

Is the SVG placeholder generator free to use?

Yes, this SVG placeholder generator is completely free to use with no limitations. All processing is done client-side in your browser, so there are no server requests or usage limits. You can generate as many placeholder images as you need for any project, including commercial projects.
