About this tool
Every layout needs images before the real ones exist, and this generator makes the stand-ins: placeholder images rendered right in your browser. Set any width and height up to 4000 pixels, pick the background and text colors, add an optional label, and download the result as PNG, JPEG or WebP. Use the placeholders to hold space in a mock-up, check how a page handles different aspect ratios, or fill a CMS while the photography is still on its way. Because each image is drawn on a local canvas, nothing depends on an external placeholder service — and nothing is uploaded.
Frequently asked questions
What do people actually use placeholder images for?
Mostly to keep work moving before final assets arrive. Designers drop them into mock-ups so clients judge the layout rather than the photos; developers use them to test that image slots, grids and responsive rules behave at real dimensions; content editors fill a CMS so templates can be reviewed. A label showing the exact size — say 1200×630 — also makes it obvious at a glance which slot each image belongs to and whether the aspect ratio is right.
Should I download PNG, JPEG or WebP?
For placeholders made of flat color and text, PNG is the safe default: it is lossless, so edges and lettering stay perfectly sharp, and every tool accepts it. JPEG produces smaller files but uses lossy compression that can smear crisp edges slightly — fine when the placeholder will sit in a slot that expects photos. WebP combines small size with good quality and is supported by all modern browsers, making it a good match for web mock-ups.
Are the images created on a server?
No — each image is drawn on an HTML canvas by your own browser and downloaded straight from there; no request is made to a placeholder service. That has practical benefits beyond privacy: it works offline once the page is loaded, there are no rate limits or broken hotlink URLs that fail when a third-party service goes down, and generating a 4000-pixel image is as instant as a small one.
