Can I create placeholders at any size?

Yes. Enter any width and height in pixels and the image is generated immediately. Common sizes like 800×600, 1920×1080, and 1:1 squares are preselected for convenience.

Can I add custom text to the placeholder?

Yes. The image displays the dimensions by default (e.g. "800×600") but you can replace this with any text, such as a label or description.

What format is the output?

Placeholder images are generated as PNG. You can download the file or copy it as a data URI for inline embedding in HTML.
