Placeholder Image Generator

Our Placeholder Image Generator outputs all three. PNG is best for crisp UI mockups with transparency, JPG for smaller file sizes when you don't need transparency, and SVG when you want infinite scaling and tiny file size. SVG placeholders are essentially text plus a coloured rectangle, often under 1 KB. Pick the format from the dropdown, set the dimensions, and hit download. For Figma or Sketch mockups, SVG is usually best because it scales without blur. For final HTML prototypes, PNG keeps things universal. JPGs make sense when you need many images and bandwidth matters.

Easiest way: enter the display size you want, then multiply by 2 (for 2x retina) or 3 (for 3x). So a card image meant to display at 400x300 should be generated at 800x600 for retina. In your CSS, use width: 400px; height: 300px; so the browser scales the high-res image down — that's what gives you sharp pixels on Apple Retina and high-DPI Android displays. Alternatively, our generator has a "@2x" toggle that automatically doubles the output dimensions. For SVG placeholders, retina doesn't matter — they're vector and scale infinitely.

Use the colour pickers in the generator — one for background, one for text. Just paste your brand hex (or pick from the wheel) and the placeholder updates instantly. For best contrast, keep text light (#FFFFFF or near-white) on dark backgrounds, dark on light. We auto-suggest a contrast-safe text colour, but you can override it. Quick tip: while prototyping for an Indian client, I usually generate placeholders in their primary brand colour and a muted neutral so the mockup looks polished even before real images arrive. Saves a stakeholder round-trip on visual approvals.

Set width and height to the same value — 500x500, 1000x1000, whatever your grid needs. Square placeholders are perfect for e-commerce product cards, Instagram-style feeds, and avatar grids. For Indian marketplaces (Amazon.in, Flipkart, Meesho) the typical product image is 1000x1000 or 1500x1500 with a white background. Our generator lets you save a preset, so you don't re-enter dimensions every time. If you need many squares of the same size with different colours or labels, use the bulk mode (covered in another FAQ on this page). Crop-safe, retina-ready, ready to drop into Figma.

A placeholder is a temporary stand-in image used during design or while real content loads — it's content-free and exists just to reserve layout space. A thumbnail is a small, low-resolution version of a real image, usually generated on the server, used for previews in galleries or list views. Different jobs entirely. Placeholders go away once real images arrive; thumbnails stay forever as the small representation of a full-size asset. Our tool generates placeholders. For thumbnails, you'd resize and compress a real image — usually with libraries like Sharp (Node), Pillow (Python), or ImageMagick.

Use our bulk mode — paste a list of dimensions and labels, hit generate, and download all images as a zip. The format is one per line: 400x300, Hero Banner, #3B82F6. Useful when prototyping a 30-card grid or a multi-page wireframe where every image slot needs a labelled placeholder. Designers love it for Figma imports, since you can drop the whole zip in at once. If you need them in code, our tool also outputs a JSON manifest mapping dimensions to URLs. Saves a few hours when scaffolding a new product listing or news site layout.

For offline work, an inline SVG is your best friend. Just paste this into your HTML: <svg width="400" height="300" xmlns="http://www.w3.org/2000/svg"> <rect width="100%" height="100%" fill="#ddd"/> <text x="50%" y="50%" text-anchor="middle" fill="#666" font-size="20">400x300</text> </svg> No network calls, no external service. Works on flights, in metros, anywhere. Our generator can also export an offline-ready HTML snippet you save and reuse. Many devs keep a small library of pre-made SVG placeholders in their starter template.

Right after generating, click the "Download" button — it saves the file to your default downloads folder using the format you picked (PNG, JPG, or SVG). On mobile, long-press the preview image and choose "Save image". For bulk downloads we package everything into a zip. Filenames follow the pattern placeholder-400x300.png so you can find them easily. If your browser blocks the download, check that pop-ups aren't disabled for our domain. Our tool generates everything client-side, so no images touch our servers — your assets stay private to you.

That broken-image icon usually means the browser couldn't load the file. Most common reasons: a typo in the URL or src path, the file doesn't exist where you said it does, you're loading from http:// on an https:// page (mixed-content block), or the placeholder service is blocked by your firewall or corporate proxy (common on Indian office networks). Check the browser's Network tab in DevTools — it'll tell you whether it's 404, blocked, or CORS-related. If you're using our generator's data-URL output, those don't depend on any external server and won't break.
