About Lorem Picsum URL Builder
The Lorem Picsum URL Builder generates ready-to-use placeholder image links from the popular picsum.photos service, so you can drop realistic images into mockups, prototypes and demos without hunting for assets.
Set a width and height and the tool assembles the correct URL for you, with a live preview so you can see exactly what you will get before you copy it.
All the common picsum options are covered.
Choose a square crop by ignoring the height, lock onto a specific photo with an image id, or supply a seed to get a stable random image that stays the same across reloads — handy for consistent design reviews and snapshot tests.
You can convert the image to grayscale, apply a Gaussian blur from one to ten, and request a particular file format such as jpg or webp.
The builder validates your inputs and explains any problem in plain language rather than producing a broken link.
Because the URL is constructed entirely in your browser, nothing about your project is sent anywhere; only your own browser fetches the preview image directly from picsum.photos.
Copy the finished URL with one click and paste it into HTML, CSS, a CMS or your favourite design tool.
FAQ
What is the difference between a seed and an image id?
A seed returns a stable random image for that text, while an image id always points to one specific photo from the Picsum library.
Why does the preview need an internet connection?
The URL is built locally, but the preview image itself is fetched live from picsum.photos, so loading the picture requires a connection.
