Dummy image URL
Embed dummy images by URL
Often a width × height image URL is enough. dummyimages.dev serves the image on demand — for HTML, CSS, Markdown, and demos.
URLs that cache well
Image URLs need no login and can be cached. Useful for staging, docs, and component demos when real media is missing or too heavy.
Pick the right format
WebP and AVIF for modern pages, PNG when you need transparency, JPG for classic uploads. That way you can check whether fallbacks and format choices actually work.
From generator to URL
Set the parameters in the generator, then copy the finished URL or HTML/CSS snippet. No upload, no account.
What the parameters control
Besides width and height you can set background, text color, label, quality, and pattern — so URLs stay clear in docs and demos.
Staging and caching
Responses work well with browser and CDN caches. On staging you can leave placeholders until real media goes live.
FAQ
Does the URL change on every request?
No. The same address with the same parameters always returns the same image.
Does it work in Markdown?
Yes. The absolute image URL works in README, Notion, and docs images.
