Placeholder Image Generator

About placeholder images

What is a placeholder image used for?

A stand-in image for mockups, wireframes, and layout testing before real assets exist — so you can see how a design handles image dimensions, aspect ratios, and loading states without waiting on final photography or artwork.

Why offer PNG, JPEG, WebP, and SVG?

Different situations call for different formats: PNG for a clean lossless test asset, JPEG because some upload forms and APIs specifically validate against that format, WebP for a modern compressed asset, and SVG for a crisp, infinitely scalable placeholder with a tiny file size.

Does WebP work in every browser?

It depends on the browser's canvas image-encoding support. Every current major browser supports it; on the rare browser that doesn't, the canvas API automatically falls back to PNG, and this tool reflects whichever format actually got produced in the size/format readout.

Does this tool upload my data anywhere?

No. Every image is generated entirely in your browser using the Canvas API (or, for SVG, plain markup) and never leaves your device.

Configuration options

Preset

Fills in a common width/height combination. You can still fine-tune the dimensions afterward — editing them switches the preset back to Custom.

Label text

Text drawn in the center of the image. Leave it blank to default to the pixel dimensions themselves, e.g. "800 × 600".

Format

PNG and WebP are lossless-ish and best for a clean test asset; JPEG is included because some systems specifically require it; SVG is markup-based, so it stays crisp at any size with the smallest file size.
