About Filestack

Originally a file picker, now an entire file infrastructure


What is Filestack?

Filestack is a developer service for file uploading in the exploding realm of user-created content. Like APIs from other parts of the technology stack, such as Stripe and Twilio, Filestack allows software developers to integrate more than 25 of the world’s leading cloud drives with just a few lines of code. End users can upload content from websites and mobile apps like Facebook, Instagram, and Dropbox or wherever that content is stored.

Filestack enables developers to upload and store large files, transform and manipulate images and other file types, and deliver that content with blazing speed, responsively, across any type of desktop or mobile device. Filestack is headquartered in San Antonio, Texas and has been used by more than 50,000 app developers around the world.
