Online Placeholder Image Generator

Generate placeholder images of any size with custom background color, text, and output format (PNG or SVG). Placeholder images are essential for frontend development, prototyping, and layout design—they simulate where final images will appear, ensuring your layout is correct before real images are available. All generation happens locally in your browser.

PNG vs SVG Placeholders

  • PNG (bitmap): Best for simulating article covers, photo walls, and other bitmap scenarios. Larger file size.
  • SVG (vector): Best for logo and icon placeholders. Scales infinitely, typically only a few hundred bytes—far smaller than PNG.

Custom Text

Display any text on your placeholder. The default shows the dimensions (e.g., 800×600). Custom text is useful for annotating image purpose (e.g., "Ad Slot", "User Avatar") to facilitate communication between designers and developers during the prototyping phase.

Preventing Layout Shift

Using properly sized placeholder images during development prevents Cumulative Layout Shift (CLS)—a key Core Web Vitals metric that affects SEO rankings. By reserving space with placeholders, your page layout remains stable as real images load.

Placeholder FAQ

What is a placeholder image and what is it used for?
A placeholder image is a temporary image used during page development and prototyping to simulate the position, size, and proportions of the final image. Developers use it to fill layouts and ensure correct typography before real images are available, preventing layout shift.
Should I choose PNG or SVG placeholder?
Choose PNG for bitmap scenarios (such as simulating article covers or photo walls). Choose SVG for vector scenarios that need arbitrary scaling and smaller file sizes (such as logo or icon placeholders). SVG placeholders are typically only a few hundred bytes, far smaller than PNG.
Does it support custom text?
Yes. You can display any text on the placeholder image. The default shows the dimensions (e.g., 800×600). Custom text is often used to annotate image purpose (e.g., "Ad Slot", "User Avatar") to facilitate design and development communication.
Are generated placeholders uploaded?
No. Placeholder images are generated locally in the browser using Canvas or SVG DOM and download directly to your device without passing through any server.
