Document Library Vs Asset Library

Question

Is there major difference between Document library and Asset Library in terms of functionality, Workflows, Document Sets or any other?

I got a task to create document sets which may hold word, pdf, image, excel, ppt files. It will have approval workflow on the documents. Also client want a thumbnail view for the same.

Since Asset library comes with Thumbnail view, I am planning to use it. Am I making the correct choice?

Update:

The library will have more images compare to office files.

Answer 1

Asset Library is preconfigured to manage media content like images, audio and video files. It has extra features over document library like Thumbnail view, Automatic metadata extraction for image files.

Yes, you can use it for sure to upload documents and use extra features that come with asset library. Also you can add workflow and other features like versioning and everything that's possible in document library. Only thing you need to do is to add new content types for Document and document set.

But remember that it's specially created to manage rich content (Media content).
