Have a GeoJSON file you need to show as a picture, but no map software handy? This page renders GeoJSON geometry into a bitmap image you can open, drop into a document, or share.

How to convert GeoJSON to an image

  1. Upload a GeoJSON file (.geojson or .json) up to 2 MB.
  2. Press Convert file and download the BMP image.

What you get

A 1024 × 1024 BMP bitmap with every geometry from the file drawn in a single colour on a white canvas. The image always covers the full world extent in longitude/latitude, so each feature lands exactly where it sits on the globe. The render comes straight from the geometry data with no intermediate styling steps.

When this helps

  • Making a quick thumbnail of a boundary, route, or set of markers
  • Embedding map data in a report, slide, or README where a live map is not possible
  • Checking that a GeoJSON file actually contains the shapes you expect

Limits worth knowing

The canvas is world-sized, so data covering a tiny area (a single building or street) renders as a small mark. Text, labels, and per-feature colours are not part of the output. Geometry that is malformed or outside the supported coordinate range is skipped, and a file that is not valid GeoJSON at all is rejected with an error. The delivered format is BMP: use a small converter if you specifically need PNG bytes.
