  4. Optionally add text, border, and apply effects like blur or contrast
  5. Copy the SVG code or download as an SVG file

Dimensions & Size

Control the exact dimensions of your placeholder image. The default size is 400×300 pixels, but you can set any width and height values.

Dimension Settings:

  • Width: Set the horizontal size in pixels (e.g., 800)
  • Height: Set the vertical size in pixels (e.g., 600)
  • Border Radius: Round the corners of your placeholder
  • Pattern Scale: Zoom pattern in or out (0.5x to 2x)
  • Rotation: Rotate the pattern (0° to 360°)

Tip: For responsive designs, use percentage-based values in your CSS and set the placeholder to a fixed pixel size that represents your intended aspect ratio.

Colors & Styling

Customize the color scheme of your placeholder. The tool uses a primary and secondary color that are randomly mixed within patterns.

Primary Color

The main color used for pattern elements. Click to open the color picker.

Secondary Color

The accent color mixed with the primary color in patterns.

Background Color

The base color behind the pattern elements.

Opacity & Density:

  • Opacity: Control pattern transparency (0 to 1)
  • Pattern Density: Adjust how many pattern elements appear

Text Configuration

Add customizable text to your placeholder. The text is automatically centered and can be toggled on or off.

Custom Text

Enter any text you want to display (e.g., "800 × 600", "Coming Soon")

Font Settings

Adjust font size, weight, and text color independently

Text Options:

  • Show Text: Toggle text visibility on/off
  • Font Size: Adjust text size in pixels (default: 24px)
  • Font Weight: Choose from light, normal, or bold
  • Text Color: Set the text color independently

Effects & Filters

Apply various image effects to customize the look of your placeholder. All effects are applied to the pattern layer only.

Blur

Apply gaussian blur to the pattern (0-5px)

Brightness

Adjust pattern brightness (0.5-1.5)

Contrast

Adjust pattern contrast (0.5-1.5)

Hue Rotate

Shift the color hue (0-360°)

Note: Filters are applied using CSS filter properties within the SVG. Some SVG renderers may not support all filter effects.

Export Options

Once you have configured your placeholder, there are several ways to use it in your projects.

Copy SVG Code

Copy the raw SVG code to your clipboard for direct use in HTML.

Download SVG

Download the SVG as a .svg file for use in design tools or as an image.

Export as Data URL

Convert to base64 data URL for use in CSS backgrounds or img src.

Example SVG Output:

<svg width="400" height="300" viewBox="0 0 400 300" xmlns="http://www.w3.org/2000/svg">
  <rect width="100%" height="100%" fill="#f8fafc" rx="12"/>
  <g transform="translate(200 150) scale(1) rotate(0) translate(-200 -150)">
    <circle cx="180" cy="140" r="20" fill="#3b82f6" opacity="0.7"/>
    <circle cx="220" cy="160" r="25" fill="#ec4899" opacity="0.7"/>
  </g>
  <text x="200" y="150" text-anchor="middle" dominant-baseline="middle"
        fill="#475569" font-size="24" font-weight="600">
    400 × 300
  </text>
</svg>

Randomize Feature

The Randomize button instantly generates a random configuration. This is perfect for inspiration or when you need a unique placeholder quickly.

What Gets Randomized:

  • Pattern type (any of the 12 available patterns)
  • Primary and secondary colors (from a curated palette)
  • Opacity level
  • Pattern scale
  • Rotation angle
  • Pattern density
  • Hue rotation
  • Blur amount

Tip: Keep clicking Randomize until you find a style you like, then fine-tune the settings manually.

Common Use Cases
