Map to HTML: Label Prep
Batch-prepare vector layer labels for HTML/Leaflet export, writing them to a separate layer style so the working style is never lost.
Before exporting a map to HTML (qgis2web and similar), this plugin applies a web oriented label preset to the layers selected in the Layers panel: black text with a light buffer derived from each layer's symbol colour, one font and size, horizontal placement and scale based visibility. The settings are written to a separate "Web" layer style, so the style you work with stays untouched and one button switches back to it. Buffer colours can be overridden per layer and are remembered in the project file. Settings that an HTML export cannot reproduce (curved labels, callouts, shadows, geometry generators) are listed as warnings. The interface is available in English and Japanese.
