XYZ Tile Coordinate Converter

Convert between latitude/longitude and slippy map tile coordinates used by OpenStreetMap, Google Maps, and more.

Bi-directional Conversion

Convert from geographic coordinates (latitude, longitude, zoom) to tile coordinates (X, Y, Z), or reverse — from tile coordinates back to geographic bounds. Get NW/SE corners and center point for any tile.

Quadkey & Tile URLs

Automatically generates Bing Maps Quadkey for any tile. Get ready-to-use tile URLs for OpenStreetMap, Google Maps Satellite, and Bing Maps. Copy and paste directly into your application.

Browser-side Processing

All tile calculations run entirely in your browser using pure math — no external libraries or server calls needed. Your coordinate data never leaves your device.

How to Use the Tile Calculator

1

Choose Conversion Direction

Select 'Coordinates → Tile' to find the tile for a location, or 'Tile → Coordinates' to find the geographic bounds of a tile.

2

Enter Values

For coordinate mode, enter latitude, longitude, and zoom level. For tile mode, enter X, Y, and Z (zoom) values.

3

View & Copy Results

Features

XYZ Tile Coordinates

Standard slippy map tile numbering used by OpenStreetMap, Leaflet, MapLibre, and most web map libraries.

Bing Maps Quadkey

Single-string tile identifier used by Bing Maps. Each character encodes one zoom level of the tile hierarchy.

Geographic Bounds

Get NW corner, SE corner, and center point coordinates for any tile. Useful for debugging tile alignment.

Tile URL Templates

Ready-to-use URLs for OSM, Google Satellite, and Bing Maps tiles. Copy and open to preview the tile image.
