Uploadcare

Uploadcare is a developer-focused service that takes care of the whole file pipeline for web and mobile apps: receiving uploads, storing files, transforming them and delivering them to users. It is meant for engineering teams that would rather integrate a hosted building block than build and run their own upload infrastructure.

On the front end it supplies a ready-made File Uploader widget that works with major JavaScript frameworks such as React, Vue, Angular, Svelte and Next, and an Upload API for custom flows that handles direct, multipart and URL uploads, metadata and malware scan reports. Server-side options include signed uploads, validation of file type and size, malware and NSFW filtering, and connecting an AWS S3 bucket. Every uploaded file is immediately available on an image or video CDN, where URL changes resize or optimize images in real time.

Uploadcare is proprietary and delivered as a hosted service. The homepage offers a free start and a demo, and documentation, SDK integrations, a CLI and a changelog are provided for developers; plans are on its pricing page.
