Bring any webpage layout into Oxygen builder for WordPress and start customising in no time. Stop wasting time trying to do it the 'right way'. Use Nimbufy with Oxygen builder. Watch demonstration videos
Here is an attempt to clear your doubts, until you see it in action yourself.
Yes. That is exactly what it does. It gets you any html layout along with complete styling, into Oxygen Builder. Where you can edit it or customise it the way you like.
The Nimbufy plugin itself is free to install. This plugin acts a client to connect to the Nimbufy service in a secure way. The service is used to convert the HtML data into oxygen format. You pay a very nominal price only for the data that you convert.
Whenever you issue a request for converting any layout to Oxygen, 1/15th the size of data to be processed in Kilo bytes that Nimbufy server receives, is deducted from your account. The data estimate button on the Nimbufy popup provides you the accurate measurement of the expected credits to be used for a particular request.
No, the images are never a part of the Oxygen Data. It contains only the links to the images involved, but direct images are not downloaded. So, you will never charged for the size of the linked images.
A regular web page can take anywhere between 200 Kbs to 2000 Kbs (basic to overy complicated pages), if solely built using Nimbufy. The additional benefit comes from the fact that you need to convert a block only once, and then you can save it as a reusable or in the block library in order to use it later. Please watch videos posted at the Nimbufy Facebook Page to have a better idea of how many KBs usualy such requests cost.
Yes, the system is in continuous development and is getting better by the day. For now, it would be safe to avoid importing slideshows, carousels and complex navigation menus. It may not be able to display imported icons in some cases, but there will be placeholders for the missing icons which you can easily replace with the Oxygen Icons
