How to Use Placeholder Image Generator
Specify the dimensions
Enter width and height in pixels to match the design slot you're filling, whether that's an avatar, a banner, or a content image.
Customise appearance (optional)
Adjust the background colour, text colour, custom label, and image format. The defaults work fine for most situations, so changes here are optional rather than required.
Generate the URL or download the image
The tool returns either a URL you can drop into an <img src> attribute or an image file ready to download for use in design mockups.
Replace before publishing
Placeholders belong only in development. Search the codebase for placeholder URLs and image filenames before each deploy so none slip into production.
When to Use Placeholder Image Generator
Mockups and wireframes
When the final imagery hasn't arrived yet, designers still need to show clients what a layout will feel like. Dimensionally accurate placeholders let you walk a client through the page structure without distracting them with stand-in artwork that may look out of place.
Frontend development
Building responsive layouts means stress-testing every breakpoint with images of unfamiliar sizes. Generating precise dimensions on demand lets you verify grid behaviour, flexbox alignment, lazy loading, and fallback strategies before any real assets exist.
Email and template design
Email templates typically need 600-pixel-wide imagery, often at retina densities, before the marketing team has chosen a single photo. Custom-sized placeholders in brand-matched colours keep the design review productive while final assets are still being commissioned.
Educational content
Tutorials and course materials sometimes need an image that's clearly an image without the content of the picture stealing focus from the lesson. A neutral placeholder fills the visual slot without semantic baggage.
Placeholder Image Generator Examples
Specific dimensions
300x200A URL like https://placeholder.com/300x200 that returns a 300 by 200 grey placeholder image.This is the everyday case. You drop the URL into an <img> tag and the right-sized image appears, no asset pipeline required.
With colour
400x300 in blueA URL such as https://placeholder.com/400x300/3b82f6/ffffff produces a blue rectangle with white text.Both background and text colours are passed as hex codes, optionally with custom label text. Matching brand colours during design review makes the mockup feel one step closer to finished.
Themed placeholders
Cats, dogs, or random nature photosServices like placecage.com, placedog.net, and picsum.photos return themed images at the requested size.Picsum's real photographs feel less 'placeholder-y' than abstract grey rectangles, which can be helpful when you want a mockup that looks closer to the finished product.
Tips & Best Practices for Placeholder Image Generator
- 1.Always use the exact dimensions your design calls for. Asking for something close and letting the browser scale it almost guarantees blur or distortion in the actual layout.
- 2.Plain grey placeholders keep the focus on the design itself, while colourful or photographic ones can pull attention away from layout problems you're trying to spot.
- 3.Treat placeholders like Lorem Ipsum and replace them before launch. Searching the codebase for 'placeholder' before each deploy catches the embarrassing ones that slip through.
- 4.Most placeholder services cache aggressively, so the same URL will return a near-identical image for a long time. Don't bust the cache for no reason.
- 5.Sending a request to an external service does reveal the dimensions you asked for and your site's referrer. Low-stakes for marketing pages, worth thinking about for sensitive prototypes.
- 6.For offline work or privacy-sensitive prototypes, the browser's Canvas API can render placeholders locally without making any network calls.
