Customize the label text displayed on the placeholder, or toggle automatic dimension text (e.g. '800 × 600').
Choose background and text colors using visual color pickers or one-click theme swatches.
Select an overlay pattern such as Blueprint Grid, Architectural Crosshair, or Subtle Diagonal Stripes for wireframe mockups.
Preview the live vector graphic update instantly in real time with aspect ratio and payload size metrics.

Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

No. All placeholder images and SVGs are synthesized 100% inside your browser session using native vector SVG rendering and the HTML5 Canvas API. No external HTTP requests, image servers, or tracking scripts are involved.

Yes! You can copy the clean vector SVG markup to embed directly into JSX/HTML, or copy the Base64 Data URI to use as an inline CSS background-image or src attribute in <img> tags without needing an image host.

When you click 'Download .png', an offscreen HTML5 Canvas draws the exact SVG markup at your specified pixel dimensions and exports a lossless, high-resolution PNG blob directly to your device via client-side download.

You can choose between Clean Solid, Blueprint Grid, Architectural Crosshair (with center axis and diagonal guidelines), and Subtle Diagonal Stripes. These patterns are especially helpful for wireframes, prototyping, and layout debugging.

Yes. Because the primary output is pure vector SVG, it scales infinitely without quality loss on any display density. For PNG downloads, you can input exact dimensions up to 4000×4000 pixels.

The workspace includes presets for 1080p Full HD (1920×1080), 720p HD (1280×720), OpenGraph/Social Media preview cards (1200×630), Web Content (800×600), Card Thumbnails (600×400), Instagram Square (1080×1080), Avatar/Icon (150×150), and Google Ad Banner formats (300×250, 728×90).
