How to Use

Create lightweight SVG placeholder images for your designs, wireframes, and development projects. Every step runs in your browser — nothing is uploaded.

Set Dimensions: Enter a custom width and height (1-4000px), or click a preset like OG Image (1200x630), HD 1080p (1920x1080), Avatar (150x150), or Banner (728x90).
Choose Colors: Pick a background color and text color using the color pickers. The default gray scheme works well for neutral wireframe placeholders.
Customize Label: Leave the label blank to display "W x H" dimensions automatically, or type custom text like "Hero Image" or "Product Photo".
Add Texture: Drag the texture slider to apply a subtle paper-like noise effect using SVG filters. Higher values produce a more pronounced organic texture.
Set Border Radius: Round the corners by adjusting the border radius slider. The maximum is constrained to half the shortest dimension.
Export: Switch between Preview, SVG Code, and Data URI tabs. Download as SVG or export as PNG. Copy the current tab content with the copy button.

About This Tool

What Are SVG Placeholders?

SVG placeholder images are lightweight, scalable graphics used during design and development to represent final images that are not yet available. Unlike raster placeholders (PNG, JPEG), SVG placeholders describe their content mathematically — a 1920x1080 SVG placeholder weighs under 500 bytes, identical to a 100x100 one. This makes them ideal for prototyping and wireframing where dozens of placeholders may appear on a single page without impacting load times.

SVG vs URL-Based Placeholder Services

Services like placeholder.com and dummyimage.com generate placeholders via URL requests (e.g., https://via.placeholder.com/800x600). While convenient, they require an internet connection, introduce external dependencies, and add HTTP requests. This SVG generator produces self-contained output that works offline, has zero external dependencies, and can be embedded directly in HTML, CSS, or Markdown without additional network requests.

Inline SVG vs Data URI

The SVG Code output can be pasted directly into HTML as inline markup, which eliminates an HTTP request and allows CSS styling of individual SVG elements. The Data URI output base64-encodes the SVG into a string usable in <img src="..."> attributes, CSS background-image declarations, and Markdown ![alt](data:...) syntax. Inline SVG is smaller (no base64 overhead) but cannot be used in <img> tags. Data URIs work everywhere images are accepted but add ~33% encoding overhead.

Texture Effects with SVG Filters

The texture option uses SVG's feTurbulence and feDiffuseLighting filter primitives to generate procedural noise patterns. These filters create organic, paper-like surfaces entirely in the SVG markup — no external image files needed. The result renders at any resolution without pixelation. Texture adds roughly 200-300 bytes to the SVG file size, a negligible increase compared to the visual improvement it provides for design mockups.

PNG Export for Compatibility

While SVG is the recommended format for development placeholders, some platforms and tools do not support SVG images. The PNG export button rasterizes the SVG to a pixel-based PNG using the browser's Canvas API. The conversion happens entirely client-side — no server processing. The resulting PNG file will be larger than the SVG source but is universally compatible with image editors, social media platforms, and email clients.

Why Use This Tool

Privacy-First, Offline-Capable

Every operation — SVG generation, data URI encoding, PNG rasterization — runs in your browser via JavaScript and the Canvas API. No files are uploaded, no external APIs are contacted, and no analytics track your placeholder configurations. The tool works fully offline once loaded, making it suitable for air-gapped environments and sensitive design projects.

Common Use Cases

Designers use SVG placeholders in Figma and Sketch prototypes to reserve image space with correct aspect ratios. Frontend developers embed them in HTML templates and component libraries during development, replacing them with real images later. QA engineers use sized placeholders to test responsive layouts across breakpoints. Technical writers include them in documentation to illustrate image placement without committing large binary files to version control.

FAQ

Why use SVG for placeholder images?

SVG placeholders are resolution-independent and typically under 1 KB regardless of declared dimensions. A 1920x1080 SVG weighs the same as a 100x100 one because SVG describes shapes mathematically rather than storing pixel data. This makes SVG ideal for development, wireframes, and prototypes where fast page loads matter.

Can I use the generated SVG inline in HTML?

Yes. Copy the SVG code from the SVG Code tab and paste it directly into your HTML. Inline SVGs render without an additional HTTP request and can be styled with CSS. Alternatively, use the data URI output to embed the SVG in an img src attribute or CSS background-image property.

What does the texture slider do?

The texture slider applies an SVG feTurbulence filter to create a subtle paper-like or organic texture on the background. At 0% the background is flat color. Higher values increase the noise frequency and surface relief, giving a more tactile appearance without adding significant file size.

Can I export the placeholder as a PNG?

Yes. Click the Export PNG button to rasterize the SVG to a PNG file using the Canvas API. The PNG is generated entirely in your browser — no server upload. The resulting file will be larger than the SVG but is compatible with tools and platforms that do not support SVG.

Is my data processed on a server?

No. All SVG generation, data URI encoding, and PNG rasterization happen entirely in your browser using JavaScript and the Canvas API. Nothing is uploaded to any server, and the tool works fully offline once loaded.
