Ready-made packages

Or grab a custom map package from a provider, then paste its direct .pmtiles or .mbtiles link below to download it straight into your offline catalog.

Tip: very large packages (multi-GB) are best downloaded in a browser, then loaded with Import on the previous screen — that streams to disk instead of holding the file in memory. Downloads require the host to allow cross-origin requests.
