UploadCN blocksfor shadcn/ui.

UploadCN, by Hanzala, focuses on one job: file uploads for shadcn/ui apps. The UI is copied into your project like any shadcn component, while open-source npm packages handle the hard parts behind it, including validation, in-browser cropping and compression, queues with concurrency and per-file progress, retries with backoff, resumable multipart transfers and waiting out offline periods. Files can go straight to S3 or R2 with presigned URLs, or to Cloudinary, local disk or your own API, and server helpers add virus scanning and OCR.

The blocks range from practical dropzones, avatar and image uploads, CSV import, upload tables and document checklists to playful animated versions shaped like envelopes, vinyl records, rockets and polaroids. Components follow every shadcn style and work with Radix, Base UI or React Aria. It's free and MIT licensed.
