Perhaps a dumb question but I've tried searching and came up empty; is there a list of all supported extensions/formats that work with previewgenerator?

There is no such list. Previewgenerator automatically supports all preview formats of your Nextcloud server. E.g. if a preview can be generated by the Files app it can also be generated by the Previewgenerator app.

In fact you can't add support for a specific file type to the Previewgenerator app. You always need to enable the preview provider on your server in order for the app to generate previews for that file type.

Please refer to the following sections of the documentation for more info:

• https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html#previews
• https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/previews_configuration.html

Here is a list of all preview providers which are included in Nextcloud by default:

Additional providers can be installed via custom apps. Unfortunately, I don't know of a comprehensive list of those.
