Storage Aliases

Store your files into one of our supported storage providers and utilize the full power of Filestack’s APIs and add-ons.

Why You Need Storage Aliases

If you have an existing storage provider for your files, Filestack can easily integrate with it instead of having to remove and re-write your business logic entirely.

You have the option to quickly plug Filestack into your application without having to create and manage an entirely new server for your files.

What Are The Benefits Of Storage Aliases

Simply create aliases for private cloud storage areas (at the granularity you desire) and we

create a secure, abstracted URL for the content within that storage that can be transformed and served

– without re-uploading content and keeping the storage private.

Then you will be able to apply Filestack transformation and processing API, for example:

  • NSFW Icon


    Never worry about serving NSFW content again. Filestack’s Image Tagging API ensures that all files within your system are safe for everyone.

  • Video Transformations Icon

    Video Transformations

    Filestack can transform any video format to your desired outcome, ensuring a uniform and easy-to-manage video format as a result. Learn more.

Document Conversion API

Learning materials come in different filetypes, and this should never be a problem. Filestack's transformations convert files to your desired filetype.​


Simple virus and malware detection for all file types

Scan every file upon upload for viruses and malicious programs no matter what their file type. Filestack's virus detection capabilities support scanning every file from images and video files to PDF documents for a secure document upload every time.
