If you’ve ever built a Google Map with multiple pins and wished you could label them A through Z — or number them 1 through 25 — without hunting down a third-party icon pack or firing up a design tool, this is for you. The Martech Zone Map Marker Maker lets you generate a full set of custom PNG map markers directly in your browser, choosing your own background color, border color, and label style, then download them all as a single ZIP file ready to drop into any mapping project. No design software, no external service, no account required.

How to Use The Map Marker Maker
To generate your markers:
Start by choosing a background color — this fills the pin’s body.
Set the border and text color, which controls both the outline of the pin shape and the letter or number rendered inside it.
Enter the colors as hex values directly or use the color picker.
Next, set how many markers you need: up to 26 for alphabetic sets or up to 99 for numeric.
Select whether you want Alpha labels (A, B, C…) or Numeric labels (1, 2, 3…).
Click Generate Markers.
The tool generates each marker one at a time, showing you a live status update as each one is created on the server. Once all markers are ready, they are automatically packaged into a ZIP file, and a download link appears. The ZIP contains one PNG per marker, named marker_A.png, marker_B.png, and so on, ready to reference directly in your project. Downloaded files are automatically removed from the server after 24 hours.
Limitations
Each PNG marker is rendered at 40×56 pixels, the standard size for Google Maps pin icons, and works well at typical map zoom levels. The tool caps generation at 100 markers per run to keep server load reasonable. Numeric sets top out at 99, and alpha sets at 26, naturally, so in practice, you’ll rarely approach the limit. The markers are flat-color PNGs with a transparent background, so they won’t match a custom-illustrated style, but they cover the vast majority of practical labeling needs.
Using Custom Markers in Google Maps
Once you’ve downloaded your ZIP and uploaded the PNGs to your server, referencing them in the Google Maps JavaScript API is straightforward. Pass the image URL as the icon property when creating each marker, and the API will substitute your custom pin for the default red teardrop.
const map = new google.maps.Map(document.getElementById(‘map’), {
zoom: 12,
center: { lat: 39.7684, lng: -86.1581 }
});
const locations = [
{ label: ‘A’, lat: 39.7684, lng: -86.1581 },
{ label: ‘B’, lat: 39.7750, lng: -86.1650 },
{ label: ‘C’, lat: 39.7600, lng: -86.1500 }
];
locations.forEach(function(loc) {
new google.maps.Marker({
position: { lat: loc.lat, lng: loc.lng },
map: map,
icon: ‘/wp-content/uploads/map-markers/marker_’ + loc.label + ‘.png’,
title: ‘Location ‘ + loc.label
});
});
The icon path simply points to wherever you’ve uploaded the PNGs — adjust the base URL to match your folder structure. If you’re building a map where the pin labels correspond to numbered list items on the same page, pairing numeric markers with a matching ordered list is an effective way to give readers a clear visual reference between the map and your content.
