What are placeholder images?

Placeholder images are simple coloured rectangles used in wireframes and prototypes before real images are available. They show the intended dimensions and position of images in a design.

Frequently Asked Questions

What does FauxImage do?
Generate placeholder images with custom dimensions, colours, and labels — download as PNG, JPG, or GIF for mockups and wireframes.
What dimension format should I use?
Enter width × height with an x separator — e.g. 1200x630, 400x300. Both values must be positive integers.
Is this tool free?
Yes, completely free with no sign-up required.
Is this tool free to use?
Yes. All Skybin developer tools are free with no account, API key, or usage limits.
Does my data get sent to a server?
No. Processing runs in your browser whenever possible. Sensitive input never leaves your device unless a tool explicitly fetches a URL you provide (e.g. OG Validator).
Can I use this on mobile?
Yes. The tools work in modern mobile browsers, though a desktop screen is easier for large JSON or PDF workflows.
How is this different from desktop apps?
There is nothing to install or update. Open a bookmarked URL and start working — ideal for quick tasks during development or support calls.
Are there keyboard shortcuts?
Most tools support standard paste (Ctrl+V / Cmd+V) and select-all in text areas. Copy buttons provide one-click output.
Does Skybin store my history?
No. We do not log tool inputs or outputs. Refreshing the page clears in-memory state unless the tool encodes state in the URL.
