Everything made on Tilda can be easily exported to your server.
Go to Project Settings > Export
Click on 'Download Archive', wait just a few second for the pages to archive, then follow the link that will appear under the file list. Save the zip-file on your computer.
Unzip the file to get the folder that contains all the files of your project.
Connect to your server via FTP and copy your files there. Rename the file htaccess to .htaccess
Additional options: Special path names
You can create your own path names if you use your own CDN or if default names of pictures, CSS and JS files do not work for you.
