Filestack provides a file uploader and upload API that lets developers fetch, transform, and deliver user files from multiple sources with a simple integration. It emphasizes a Content Ingestion Network for reliable mobile uploads and URL-based transformations and conversions on the network.

The product offers a JavaScript/SDK-based file picker and upload API that enables uploading from local disk and over 20 integrations (e.g., Dropbox, Google Drive, Instagram). It supports subsequent transformations (image/video/document/audio) on the network, URL-based conversions, and secure delivery via a CDN. It includes a content ingestion network to improve mobile upload reliability, and provides embeddable viewers and SDKs for multiple languages to integrate the workflow into apps and websites.
