About the Image Placeholder Generator
The Image Placeholder Generator builds a flat placeholder image at any size with a background color, text color, and label you choose. It is handy for mockups, layout testing, blog drafts, and reserving image slots before final assets exist. The image is drawn with the Canvas API in your browser, so nothing is uploaded and you get a real PNG file plus a data URI you can paste directly into HTML or CSS.
How it works
- Set the width and height in pixels, or click a preset such as OG image or 1920×1080.
- Pick a background and text color with the swatch or by typing a hex value.
- Type a custom label, or leave it blank to show the dimensions automatically, and choose a font.
- Download the PNG, or copy the data URI string to paste straight into your markup.
Features
- Any size up to 4096×4096, with one-click presets for common formats.
- Custom background and text colors via color picker or hex input.
- Custom label text that defaults to the image dimensions.
- Sans serif, serif, or monospace label fonts.
- Download a PNG file or copy the data URI, all generated in your browser.
Frequently asked questions
Is the image uploaded anywhere?
No. The placeholder is drawn with the Canvas API inside your browser. The PNG download and the data URI both come from that local canvas, so nothing is sent to a server.
What is the largest size I can make?
Each dimension can go up to 4096 pixels. Very large sizes produce a longer data URI and a bigger PNG, but they still render in the browser.
What is a data URI and how do I use it?
A data URI is the full image encoded as a text string. You can paste it into an img src attribute or a CSS background-image url() to embed the placeholder without hosting a separate file.
Can I set the label to show the dimensions?
Yes. Leave the label field blank and the image shows the current width and height, for example 800×600. Type your own text to override it.
What format is the downloaded file?
The download is a PNG. The file name includes the dimensions, such as placeholder-800x600.png.
