Placeholder Image Generator

How to Use

1. Set your desired width and height, or click a preset size like 600 × 400 or 1200 × 630 (Open Graph).
2. Choose background and text colors using the visual color pickers or by typing hex values directly.
3. Optionally enter custom overlay text. By default, the image displays its own dimensions.
4. Download the image or copy it as a Data URI, <img> tag, or CSS background-image property.

Why Use Placeholder Images?

Placeholder images are an essential part of the front-end development workflow. When building layouts, you rarely have final images available from day one. Placeholders let you establish visual structure, test responsive behavior, and iterate on designs without waiting for content. They are especially useful during sprint-based development where UI work runs in parallel with content creation.

Common use cases include wireframing and prototyping, testing responsive image behavior across breakpoints, populating demo or staging environments, creating design system documentation with consistent visual examples, and verifying that lazy-loading and image optimization pipelines handle different dimensions correctly.

SVG vs PNG vs JPEG

This tool supports three output formats, each with distinct advantages:

• SVG — Vector-based, infinitely scalable, and extremely lightweight. A 1920 × 1080 SVG placeholder is typically under 300 bytes. SVG is ideal for embedding directly in HTML or as a data: URI in CSS. It is the best choice for most development workflows.
• PNG — Raster format with lossless compression and support for transparency. PNG files are larger than SVG but compatible with every image processing pipeline. Choose PNG when your tooling requires a bitmap format.
• JPEG — Lossy compression produces smaller files than PNG for photographic content, but the simple shapes of a placeholder image do not benefit much from JPEG encoding. Use JPEG only when testing JPEG-specific behavior like quality settings or EXIF handling.

Common Placeholder Sizes

Different contexts require different image dimensions. Here are the most common sizes used in web development:

• 150 × 150 — Avatars, thumbnails, icons
• 300 × 200 — Card images, small thumbnails
• 600 × 400 — Blog post featured images, medium content images
• 800 × 600 — Product images, portfolio items
• 1200 × 630 — Open Graph images for social sharing on Facebook, LinkedIn, and Twitter
• 1920 × 1080 — Hero banners, full-width backgrounds, Full HD displays
• 375 × 667 — iPhone SE viewport for mobile mockups
• 768 × 1024 — iPad portrait for tablet mockups

Use the batch mode to generate multiple sizes simultaneously. This is especially useful when building responsive designs that serve different image dimensions at different breakpoints using the <picture> element or srcset attribute.

Embedding Placeholder Images

The copy buttons provide ready-to-use code snippets for the three most common embedding methods:

• Data URI — Embed the image directly in your code without a separate file. Useful for prototyping and reducing HTTP requests during development. The entire image is encoded as a base64 or URI-encoded string.
• HTML <img> tag — A complete image element with src, alt, width, and height attributes. Paste directly into your HTML template.
• CSS background — A background-image property with the data URI and matching background-size. Apply to any element as a background placeholder.

Tips for Effective Placeholders

• Use colors that match your design system so placeholders blend naturally into layouts
• Display dimensions as text so team members can immediately identify which image slot they are looking at
• Keep placeholder file sizes small — SVG data URIs are typically under 500 bytes and load instantly
• Add descriptive custom text like "Hero Banner" or "User Avatar" to make mockups more readable
• Use batch mode to generate all required sizes at once when setting up a new project
