Free Placeholder Image Generator for Web Developers
When you're building a website or app, you need images before you have actual images. Placeholder images fill that gap — they show the right dimensions and give you a visual reference while the real content is being prepared. Our placeholder image generator lets you create custom placeholders with any size, color, and text you want.
Why Developers Use Placeholder Images
During development, you don't want to wait for final assets. You need to see how the layout works with images in place. Placeholder images let you:
- Test responsive layouts — See how different image sizes affect your design at various breakpoints
- Build wireframes — Show clients where images will go without needing final photography
- Develop components — Build image galleries, cards, and grids with realistic dimensions
- Demo prototypes — Present working prototypes that look intentional, not broken
How to Generate Placeholder Images
Set your dimensions (width x height), pick a background color and text color, and optionally add custom text. The generator creates an image at exactly those specs. Download it as PNG or JPEG, or grab the direct URL to use in your code.
I usually put the dimensions as the text — like "1200×600" — so anyone looking at the mockup knows exactly what size image goes there. It's a small detail that saves questions later.
Common Sizes You'll Need
For reference, here are placeholder sizes I create most often: hero images at 1920×1080 or 1200×600, blog thumbnails at 800×400, social cards at 1200×630 (Open Graph), profile avatars at 200×200, and product images at 600×600.
The generator doesn't restrict you to preset sizes though. Need a 347×182 image for some specific component? Go for it. Any dimensions work.
Better Than External Services
Services like placeholder.com work fine, but they require an internet connection, can go down, and you're relying on a third party. Generating your own placeholders means you have the actual files — they work offline, load instantly during development, and you control the appearance.
Plus, custom colors and text make your mockups look more intentional. A gray box with "Hero Image — 1200×600" looks way better in a client presentation than a random stock photo placeholder.
