How to remove tags and street names

This seems to be answered already in how-can-i-create-a-map-without-any-names-on-it.

Hi, nice that you want to use OSM :)

You need to keep 2 things strictly seperated:

1. OSM data (that contain tags and geometries
2. OSM (online) maps (that are rendered as raster images by applying a map style to the OSM data)

So what you are looking for, is a map style without streetnames. You might use for example this online maps:

• http://maps.stamen.com/#watercolor/
• http://maps.cloudmade.com/?styleId=3
• https://www.mapbox.com/editor/

If you just want to make a single image, you might also use offline OSM data and render a small area with a local renderer. I guess Maperitive suites well and maybe they also have a no-names style.

If you're working with leaflet the easiest way is to use https://github.com/mapbox/mapbox-gl-leaflet. Pay attention to the branches if you're using an earlier version of leaflet. You can link to the style in the basic.html in the examples folder (https://raw.githubusercontent.com/osm2vectortiles/mapbox-gl-styles/master/styles/bright-v9-cdn.json) then copy and paste the info into your own file with its own name (such as style-cdn-json). From there you can modify the attributes in the style file to your liking.
