Placeholder Image Generator

About This Tool

The Placeholder Image Generator creates custom-sized images instantly in your browser using the HTML5 Canvas API. There are no server requests — everything happens locally. Specify any width and height up to 2000 × 2000 pixels, choose background and text colors, add an optional custom label, and choose between PNG (lossless) or JPG (smaller file size).

Placeholder images are widely used in web design and frontend development: filling layout space before real assets arrive, mocking up wireframes, testing responsive breakpoints, and populating database seeds with image data.

How to Use

1. Enter the desired width and height in pixels.
2. Choose a background color and text color.
3. Optionally enter a custom label — otherwise the dimensions are shown.
4. Select PNG or JPG format and click Download.

Use Cases

Frontend developers insert placeholder images during layout work so the page structure is correct before real photos are ready. UI designers use them in Figma or Sketch handoffs when stock photos aren't selected yet. Backend developers seed databases with placeholder image files for testing image-upload workflows. Teachers create labeled placeholders for HTML and CSS exercises.

FAQ

• What is the maximum image size? — Width and height are capped at 2000 × 2000 px to stay within reasonable browser memory limits. Most layouts need far less.
• PNG vs JPG — which should I choose? — PNG is lossless and ideal for logos or images with flat colors. JPG is smaller and better for photos or when file size matters.
• Is the image generated on a server? — No. Everything happens in your browser via the Canvas API. Nothing is uploaded anywhere.
