Placeholder Image Generator
Make placeholder images at any size for mock-ups, wireframes and test pages, with presets for social posts and web adverts, as PNG, JPEG, WebP or SVG.
About this tool
Pick a preset or type a width and height, choose colours, and download. The label shows the size unless you type your own, and it shrinks to fit narrow banners. The ratio under the preview helps you match a layout: 1200 × 630 is the standard size for link previews on social media, and 1080 × 1350 is the tallest a feed post can be.
Choose PNG for crisp text, JPEG or WebP for smaller files, or SVG for a tiny file that stays sharp at any size. The SVG data URI is the same image as text, which you can paste straight into an <img src> or a CSS background while you build a page, with no file to host. Images are made in your browser and your settings are remembered on this device.
