Frequently Asked Questions
What's this used for?
Placeholder images are handy for mocking up designs, testing layouts before real assets are ready, or filling space in a prototype so you can judge proportions and spacing.
What's the maximum size?
4000×4000 pixels — large enough for most mockup and print-preview needs while keeping generation fast in the browser.
Which format should I choose?
PNG for the smallest file with crisp solid colors and text (this tool's default). JPEG or WebP if you specifically need one of those formats for a testing scenario.
Is the image generated on a server?
No. It's drawn entirely in your browser using the Canvas API and never uploaded anywhere.
