Everything worth knowing before you dive in.
How it helps
Every layout mockup needs stand in images before the real photos or graphics are ready, and services that generate these from a URL pattern require an internet connection and trust in a third party server just to preview a design. This tool builds the same kind of placeholder locally using the canvas API, no network request required.
Built for real use
Set an exact pixel width and height to match a specific slot in a design, pick colors that fit the mockup's palette, and optionally add custom label text, a component name, a size note, or anything else useful while reviewing a layout. Leaving the label blank automatically shows the image dimensions, the most common default for this kind of placeholder.
Private by default
Because generation happens entirely in the browser, there's no rate limit and no dependency on an external image service staying online, useful for both quick one off mockups and larger design systems that need many placeholder sizes.
Common questions
What's the maximum size I can generate?
Width and height each go up to 4000 pixels, more than enough for most web and print mockup needs.
Can I use these placeholder images in a live website?
They work fine for prototypes and staging, though for a production site you'll want to swap them for real optimized images before launch.
Does the download include the exact colors I picked?
Yes, the downloaded PNG matches the preview exactly, including your chosen background color, text color, and label.
