Lorem Image Generator
Generate placeholder images with custom sizes
100% client-side processing
Mockups need images long before the real photography or artwork exists. This placeholder image generator creates correctly-sized dummy images right in your browser: set the width and height, pick background and text colors, add a label if you want one, and save the result as a PNG. Because it renders on an HTML5 canvas locally, it works offline and never uploads anything.
How to Use
- Set dimensions: Enter width and height in pixels, up to 2000x2000
- Choose colors: Select background and text colors with the color pickers
- Add custom text: Type a label, or leave it blank to show the dimensions automatically
- Generate: The image renders instantly on the canvas
- Save: Right-click the image and choose Save Image to download the PNG
Features
- Custom dimensions from 1 to 2000 pixels per side
- Custom background and text colors
- Optional custom label, with automatic dimension text by default
- Instant canvas-based rendering, PNG output via right-click save
- 100% client-side processing — nothing is uploaded
Why Use Placeholder Images?
Placeholder images solve a workflow problem: layout decisions should not wait on final assets. A design depends on an image’s aspect ratio and visual weight, not its content, so a correctly-sized gray box lets you judge spacing, alignment, and responsive behavior immediately — when the final art arrives, you swap the file and the layout is already proven. Placeholders also protect you from a common trap: using striking stock photos as stand-ins, which biases feedback toward the imagery and has a habit of accidentally shipping to production. A clearly-labeled placeholder — this tool prints the dimensions automatically — can never be mistaken for finished work.
Use Cases
- Wireframes and mockups: Fill image slots while the design is undecided
- Frontend development: Test responsive layouts and lazy loading with exact sizes
- CMS and demos: Seed templates and staging sites with realistic content
- Documentation: Illustrate size requirements for image uploads in specs
