Versions:
QTiles is a Windows desktop application developed by Code-iX that provides visual georeferencing and XYZ tile rendering capabilities, currently available at version 1.0.1 with two versions released to date. The software serves as both a desktop editor and a command-line renderer, designed for turning georeferenced raster images into standard XYZ map tiles, placing it within the geospatial, cartography, and mapping tools category. Its central purpose is to support manual raster georeferencing workflows in which users define control points to align source imagery with real-world geographic coordinates. The desktop editor allows alignment to be previewed directly against a basemap, so that positioning can be inspected and adjusted before any output is generated, making the tool well suited to projects where scanned maps, aerial photographs, or other raster sources must be accurately positioned. Once georeferencing is complete, QTiles renders the results as folder-based tile output, following the conventional XYZ directory structure commonly consumed by web mapping libraries and tile-serving systems. Supported output image formats include PNG, JPG, and WebP, giving users flexibility in balancing file size, compression, and image quality for their intended distribution environment. In addition to the tile images themselves, the software produces TileJSON metadata, which describes the rendered tile set so that compatible clients and services can consume it without additional configuration. The dual interface design addresses two distinct use cases: the graphical editor supports interactive, hands-on georeferencing and alignment review, while the command-line renderer enables rendering tasks to be integrated into scripts or automated build processes. Overall, QTiles targets users working with geospatial data on Windows who need a focused tool for converting raster imagery into web-ready map tiles, combining manual georeferencing with control points, basemap-based preview, multi-format tile rendering, and standards-oriented metadata output.
