Frequently Asked Questions

What is a placeholder image?
A placeholder image is a temporary image used in design mockups, wireframes, and development to represent where real content will go. It typically shows dimensions and a solid background color.
Can I use custom colors and text?
Yes! You can set any background color, text color, and custom overlay text. If no custom text is set, the dimensions are displayed automatically.
What is a Data URL?
A Data URL (data URI) is a base64-encoded image string that can be embedded directly in HTML or CSS without needing a separate image file. Useful for small images and prototyping.
Is there a size limit?
You can generate images up to 4096×4096 pixels. All processing happens in your browser using the Canvas API, so no data leaves your device.
