If you want to use inline encoding of icons for [wiki:Maps Imageries], [wiki:Presets], [wiki:Styles] or [wiki:Rules] here are some hints.

Examples:
* {{{data:image/png;base64,...databytes...}}}
* {{{data:image/svg+xml;base64,...databytes...}}}

You can use web tools to convert your image to the base64 code, e.g. [http://www.base64-image.de base64-image.de] or [https://base64.guru/converter/encode/image base64.guru].

''Before'' you convert your image to the base64 code you should minimize it to make the base64 a lot shorter (without loosing quality):
* for `.png` files: Use e.g. [http://compresspng.com/ compresspng.com].
* for `.svg` files: Use e.g. [https://github.com/RazrFalcon/svgcleaner-gui/releases svg cleaner]. When using this one you can use the "complete" preset to clean up the svg file. More information about possible problems with svg in JOSM see [wiki:DevelopersGuide/DefaultPresets#NewIcons].
