| Processing | Client-side (browser canvas rendering) |
How to Use the Placeholder Image Generator
- Enter width and height in pixels, or select a size preset from the list.
- Choose background type: Solid or Gradient.
- For solid, pick a background color; for gradient, set two colors and a direction.
- Optionally enter custom text (leave blank to show "width × height").
- Adjust text color and preview the canvas result.
- Select PNG, JPEG, or WebP and click Download to save the placeholder.
What is a Placeholder Image Generator?
Set custom width and height or pick from size presets, then choose a solid background color or a two-color linear gradient with preset direction angles. Add optional custom text (defaults to "width × height" if left empty), set text and border colors, and preview the result on a canvas. Download as PNG, JPEG, or WebP for use in mockups, wireframes, or development layouts.
The canvas draws the background fill (solid or gradient), a border rectangle, and centered text with a subtle background pad for readability. This is a local image generator — it produces actual image files you download, not a placeholder.com-style remote URL. Everything renders client-side with no server dependency.
An offscreen canvas is sized to your width and height settings. The background is filled with either a solid color or a createLinearGradient using your two gradient colors. Text is centered with measureText for sizing, and a semi-transparent background pad is drawn behind the label. Export uses canvas.toBlob at the selected format.
How it works
You set image file upload (png/jpg/webp as supported) + on-screen settings in the live panel. Placeholder Image Generator then generate custom placeholder images with specified dimensions, colors, and text. Perfect for web design mockups. Results show as processed image preview + download.
To resize actual images to specific dimensions, use our Image Resizer.
Usage scenarios
- Wireframe image slots: Generate 800×400 placeholders labeled with dimensions for a landing page wireframe.
- Gradient hero mockup: Create a 1920×1080 gradient placeholder with custom brand colors for a presentation deck.
- Component development filler: Download PNG placeholders at exact card dimensions while waiting for final photography.

Frequently Asked Questions
What is a placeholder image?+
A placeholder image is a temporary image used in design mockups, prototypes, or layouts to show where real images will go. They help designers and developers visualize layouts without final assets.
Can I use these in production?+
Placeholder images are typically replaced with real content before launch. For production, use them only if you need temporary content, or swap them for final images.
What sizes can I generate?+
You can specify any width and height in pixels. Common sizes include 1920x1080 (full HD), 800x600 (blog), 400x300 (thumbnail), and any custom dimension for your layout.
Is the placeholder image generator free?+
Yes, our placeholder image generator is completely free. Generate as many placeholders as you need for your design and development projects.

When to Use Placeholder Image Generator
- Creating correctly sized placeholder images for a web layout mockup
- Generating dimension-labeled stand-ins during frontend development
- Producing gradient or solid-color filler images for a design presentation
- Making custom-sized placeholders when external placeholder services are blocked offline
Advantages
- Custom width, height, and size presets
- Solid or gradient background options
- Custom text with auto dimension fallback
- PNG, JPEG, and WebP export
Tips
- Leave the text field empty to auto-label placeholders with their pixel dimensions.
- Use gradient backgrounds to make mockups look more polished than flat gray boxes.
- Match preset or custom dimensions exactly to your layout's image slot sizes.
- Export as WebP for smaller file sizes in modern browser-only dev environments.
Common Mistakes
Expecting a remote URL like placeholder.com — this downloads a local file instead.
Setting tiny dimensions (like 16×16) and expecting readable custom text.
Forgetting to click download after previewing — the canvas preview is not a hosted URL.
Summary
Set your dimensions, pick solid or gradient styling, add optional text, and download a PNG, JPEG, or WebP placeholder — perfect for mockups and development layouts without relying on external placeholder URLs.
