For Mapbox GL JS developers
Custom Mapbox markers, ready to paste.
Design any marker shape, pick from 40,000+ icons, and copy ready-to-use mapboxgl.Marker snippets with precise pixel offsets. No anchor approximations.
How to add custom markers to Mapbox GL JS
Mapbox GL JS's marker API takes any HTMLElement as the element option — flexible, but the snippets you find in tutorials usually include hardcoded SVG strings and approximate anchor offsets that drift visibly at large marker sizes.
MapMarker Studio gives you a precise mapboxgl.Marker snippet for any shape: an inline SVG element, anchor: 'center', and an offset[] computed exactly so the user-chosen anchor point lands on the lat/lng. Asymmetric shapes like flags work without manual offset tuning.
Browser-only. No hosting, no API key required at design time. The SVG and the snippet are static — paste, run, ship.

Frequently asked questions
How do I add a custom marker to Mapbox GL JS?
Create an HTMLElement (typically a div whose innerHTML is your SVG), then pass it to new mapboxgl.Marker({ element }). MapMarker Studio generates this exact pattern as a copy-paste snippet, including the inline SVG and the constructor call.
What's the difference between anchor and offset in mapboxgl.Marker?
anchor is one of nine snap points ('center', 'top', 'bottom-left', etc.) — the part of the marker that aligns with the lat/lng. offset is a [x, y] pixel adjustment from the anchor. For shapes that don't align with a snap point — like an asymmetric flag — combining anchor: 'center' with a precise offset is the most accurate approach. MapMarker Studio uses this pattern by default.
Can I use SVG markers with Mapbox GL JS?
Yes. The recommended approach is to inline the SVG into a custom HTMLElement (so it travels with your code and stays crisp at any zoom). MapMarker Studio's Mapbox snippet does exactly this.
How do I rotate or animate a Mapbox custom marker?
Pass a rotation (in degrees) to the Marker constructor for static rotation, or apply CSS transforms to the inner SVG element for animations. The custom-element pattern makes both straightforward — once your snippet is in, you have full control over the DOM.
Why does my SVG marker look pixelated in Mapbox?
Mapbox doesn't pixelate SVG, so a blurry marker usually means the source is a PNG embedded inside the element. Use SVG end-to-end and the marker stays crisp at any zoom level. MapMarker Studio outputs SVG by default.
