Sized dummy images on demand. Set the dimensions, colours and label, preview live, then download as PNG, JPG, WebP or SVG — all rendered in your browser.

Placeholder preview

Fill the gaps while you build

Designs rarely start with the final images in place. A placeholder that shows its own dimensions makes layout work honest — you can see at a glance whether a card slot is 300 wide or 320, whether the hero is the aspect ratio you sketched, and where text will sit once the real photo lands.

How to use it

  1. Set the size. Type the width and height in pixels, up to 4000 each.
  2. Pick colours and a label. Choose a background and text colour, and leave the label blank to show the dimensions or type your own.
  3. Choose a format and download. PNG, JPG and WebP for raster, or SVG for a crisp, scalable block.

Tips

  • Match your grid. Generate one placeholder per breakpoint width so spacing looks right at every size.
  • Reach for SVG when you want the smallest file and pixel-perfect edges at any zoom.
  • Label by role — "Avatar", "Hero", "Logo" — to keep busy mockups readable.

Frequently asked questions

What's a placeholder image for?

Placeholders fill the gaps while you design or build — stand-in graphics for hero banners, avatars, cards and galleries before the real assets exist. Because they show their exact dimensions, they make it obvious whether a layout slot is the size you expected.

Which format should I download?

PNG is the safe default and keeps text crisp. JPG makes smaller files for photo-like fills. WebP is the most compact for the web. SVG is resolution-independent — it stays sharp at any size and has the smallest file for a flat colour block.

How large can the image be?

Up to 4000 pixels on each side, which covers full-screen banners and high-resolution mockups. The label text scales automatically so it stays centred and readable at any size.

Can I change the label text?

Yes. Leave it blank to show the dimensions (like '600 × 400'), or type anything — a section name, 'Logo', 'Avatar' — to label the slot however helps your mockup.

Is anything uploaded?

No. The image is drawn entirely in your browser with a canvas (or built as SVG markup) and only saved when you click download. Nothing is sent anywhere.
