How to convert query string http://example.com/myview?page=1 to http://example.com/myview/page/1 in views?
Try using the module: Query parameter to url(https://www.drupal.org/project/query_parameters_to_url), It will work for you.

Just specify the pattern {^myview} inside /admin/config/search/query-parameters-to-url after installing and activating the module.

Let me know if any helps needed.
