Placeholder Map Generator

What Is a Placeholder Map?

A placeholder map is a stand-in map image used to fill a layout where a real map will eventually appear. Designers and developers drop one into store-locator cards, contact pages, dashboard widgets, and travel mock-ups so the interface looks finished long before a live mapping service is wired in. Each map is built from a fictional city — roads, blocks, parks, and coastlines that look real but correspond to no actual place — so there are no API keys, no usage quotas, and no real-world coordinates to worry about.

How to Use This Generator

1. Set the width and height in pixels to match the slot in your layout (any size is resized server-side).
2. Change the seed to pick a different fictional city — the same seed always returns the same map.
3. Pick a style (Default, Apple, Google, Subtle Grey, …) or leave it on Auto to choose one from the seed.
4. Choose JPEG (smallest, recommended), WebP, or PNG, then copy the URL or download the image.

You can also request maps directly by URL and embed them in any <img> tag. See the Help page for the full list of parameters.

Is This a Real Map?

No. Every map is a fictional city — the streets, neighborhoods, parks, and coastlines are entirely made up. None of it corresponds to a real address, street, or geographic coordinate, and it should never be used for navigation, distance, or any decision that depends on actual geography.

Frequently Asked Questions

Is the output deterministic?

Yes. The same URL — same width, height, seed, style, and format — always returns the identical image, so your mock-ups stay stable across reloads and builds.

What formats are supported?

JPEG (default, smallest), WebP, and PNG. JPEG is recommended for map imagery because it compresses photo-like content far better than PNG.

Does it show real locations?

No. Every map is a synthetic city. There are no real place names, streets, or coordinates behind it — it only looks map-like.

Is it free?

Yes. The maps are free for personal and commercial projects, with no attribution required and no sign-up.

The map images are pre-generated using ProbableTrain's MapGenerator (LGPL-3.0 / GPL-3.0), then resized at request time. Generated map images themselves are not derivative works of the generator source, so they remain free to use; we credit the original tool here because we appreciate the work.
