Generate an Image for Your Exact Size
A placeholder image gives your layout the right dimensions before the final asset is ready. Instead of searching for an image that is only roughly the right size, create one with the exact width and height your project needs.
Use the dummy image generator for UI layouts, prototypes, CMS media libraries, image upload testing, thumbnails, cropping, resizing, and responsive designs.
Every generated image uses the dimensions you choose, giving you a controlled image for development and testing.
Choose an Image Format
Each format generates instantly at any size
PNG images are lossless and crisp, making them useful for UI mockups, icons, screenshots, and graphics where clear edges matter.
WebP is useful for testing modern image formats, browser support, upload validation, and image processing workflows.
JPG images use compression and are useful for photo-style placeholders and common image upload testing scenarios.
GIF provides another format for testing image upload paths, format validation, and conversion workflows.
Popular Image Sizes, Easy to Generate Yourself
Choose a common size when you already know where the image will be used, or enter your own dimensions in the generator.

Use a Stable Image URL Instead of Downloading
You do not always need to download an image. Sometimes you need a predictable image URL that your application can request whenever it loads.
Testfilelab provides stable image URLs that can be used in HTML, test fixtures, development environments, and other workflows that need a repeatable image resource.
Use a stable URL when you want to place the same image directly into a page, test fixture, or development workflow.
For URL patterns and development workflows, see Testfilelab Developer Documentation.
<img src="https://www.testfilelab.com/image/generate/png/1200x630"
width="1200"
height="630"
alt="Placeholder">Testing Image Uploads?
A good image upload test needs more than one valid image. Your application may need to handle different formats, dimensions, aspect ratios, file sizes, and resizing requirements.
For the complete workflow, see the image upload testing guide.
You can also use the file validation testing guide to test file type, MIME, size, and dimension rules.
Use Testfilelab to create controlled images for testing:
- Accepted and rejected image formats
- Minimum and maximum dimensions
- Required aspect ratios
- Image upload size limits
- Thumbnail generation
- Image cropping
- Image resizing
- Image previews
- CMS media uploads
