The Placeholder Image Generator works in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the best experience, use the latest version of your preferred browser.

Match the placeholder to the slot the real image will fill so the layout reviews and tests at true dimensions. For a YouTube-style thumbnail use 1280x720, a standard social share image is 1200x630, an avatar is roughly 150x150, and a hero banner often runs 1920x1080. For responsive work, generate one placeholder per breakpoint so you can confirm spacing and cropping on mobile, tablet, and desktop before any artwork exists. This generator accepts any width and height from 1 to 4096 pixels and includes one-click presets for common sizes plus exact platform dimensions for Instagram, Facebook, Twitter/X, YouTube, LinkedIn, Pinterest, and TikTok. By default the image prints its own dimensions, making a wrong size obvious at a glance. Pick a preset or type your own values above to get a correctly sized placeholder instantly.

A PNG is a raster image made of a fixed grid of pixels, so it has a set resolution and can look soft or blocky if scaled larger than it was generated. An SVG is vector-based: it describes the rectangle and text as shapes, so it stays perfectly crisp at any size and usually has a tiny file size for a simple placeholder. Use SVG when a placeholder must scale across many screen sizes or when you want lightweight, resolution-independent markup. Choose PNG (or WebP for smaller files, JPEG for photographic-style fills) when you need a true raster image with exact pixel dimensions. This tool exports all four formats, and each download is named after its dimensions. Select your format in the options above, then download or copy the image as a Base64 data URI to paste straight into your code.

Instead of creating each image one at a time, use the Batch tab and enter a comma-separated list of sizes such as 300x200, 600x400, 1200x630. The tool renders every size in one pass, shows a preview of each, and offers a download-all option so you collect the whole set in a single step. For responsive testing there is also a Responsive Grid view that produces a placeholder for every common breakpoint, from Mobile S at 320 pixels up to 4K at 2560 pixels, with one click. Every batch image keeps the colors, style, and text you set, and each file is named after its dimensions so they stay organized in your downloads. This is ideal for filling a responsive layout or a design system mockup quickly. Open the Batch tab above, list your sizes, and generate them all together.

Blueprint Mode renders a wireframe-style placeholder: a dark grid background with labeled dimension markers and arrows showing the width and height in pixels, instead of a plain solid color block. It is useful when a mockup needs to read as deliberately unfinished, so stakeholders understand they are looking at structure and proportions rather than near-final artwork. The clear dimension labels also make it easy to confirm that each slot is the size you intended while reviewing a layout. It pairs well with low-fidelity wireframes and early design reviews where polished imagery would send the wrong signal. You can still add custom text on top of the blueprint grid for extra labeling. Toggle Blueprint Mode in the options above, set your dimensions, and download the wireframe-style placeholder for your mockup.

Yes. The Code tab gives you ready-to-paste snippets that already include your chosen dimensions: an HTML img tag with width, height, and alt text, a CSS background-image rule with cover sizing, Markdown image syntax for docs and readmes, and a data-URI image tag. The data-URI option embeds the whole image as a Base64 (or SVG) string inside the tag, so the placeholder works with no separate file and no extra network request, which is handy for quick prototypes and isolated examples. You can also copy just the Base64 data URI on its own to use wherever you need it. Because everything is generated in your browser, the snippets update the moment you change a size or color. Set your placeholder above, open the Code tab, and click copy on the snippet that fits your project.
