Instantly create dummy placeholder images at any size for mockups.
The Image Placeholder Generator creates simple dummy images at any width and height you specify, complete with a background colour and a label showing the dimensions or custom text of your choice. Developers and designers use placeholders like this constantly while building layouts before the real, final images are ready.
You choose a width, height, background colour, text colour and optional custom label text, and the tool draws a canvas of exactly that size, fills it with your chosen background colour, and writes the label centred on top using the canvas text API. The result is exported instantly as a PNG file you can drop straight into a prototype, wireframe or piece of sample HTML.
Web developers drop placeholder images into a page layout while waiting for a client's final photography to arrive. Designers use consistently sized placeholder blocks to test how a grid or gallery layout behaves with different image dimensions. Students learning HTML and CSS use quick placeholder graphics to practise building responsive image layouts without needing real photo assets.
Match the placeholder's dimensions exactly to where the real image will eventually go, so you can spot layout issues early rather than after the real photos are dropped in. Using a distinct background colour for each placeholder size makes it easy to visually scan a page and confirm every image slot is behaving as expected. Labelling each placeholder with its exact pixel dimensions helps collaborators immediately understand what final asset size is expected in that spot.
Yes, you can type any short text you like, such as a section name or asset name, instead of showing the automatic width by height label.
You can generate very large placeholders, though extremely large canvases may take slightly longer to render depending on your device's available memory.
Yes, both the background colour and the text colour are fully adjustable using colour pickers before you generate the placeholder.
Yes, it downloads as a genuine PNG file that can be used anywhere a normal image file is expected, including in live prototypes and static websites.
