Uploadcare
FREEPAY
- Free storage / trial
- Free plan includes 1 GB storage.
- Separate limits
- Free plan also lists 5 GB/month traffic, 1,000 operations/month, and 500 MB max file size.
- Billing trigger
- Free plan is for small-scale/personal projects; Pro and higher add included usage then usage fees.
- Best fit
- Small media projects that need upload widgets, CDN delivery, and transformations.
Cost hygiene:Track operations separately from storage; repeated uploads and transformations can hit the free cap before 1 GB does.

Uploadcare is an EU-based, GDPR-friendly media storage and CDN platform. AeroFTP integrates Uploadcare via its native REST + Upload APIs as a first-class StorageProvider. Shipped in v3.7.2 as the 24th protocol.
Connection Settings
| Field | Value |
|---|---|
| REST endpoint | https://api.uploadcare.com (automatic) |
| Upload endpoint | https://upload.uploadcare.com (automatic) |
| Public Key | From Uploadcare dashboard > API Keys |
| Secret Key | From the same panel |
| Auth | Public + Secret pair (Authorization header) |
How to Connect
- Sign up at uploadcare.com and create a project.
- In the dashboard, open API Keys and copy both the Public Key and the Secret Key.
- In AeroFTP, open Discover Services and pick Uploadcare from the Photo & Media tier.
- Enter the public + secret key pair.
- Click Connect. AeroFTP lists the project's stored files using the cursor-based pagination flow.
Features
- Cursor-based listing: Native pagination through Uploadcare's REST API. AeroFTP transparently follows the cursor across pages; long lists scroll smoothly.
- Store-once mapping to directories: Uploadcare uses a flat UUID model. AeroFTP layers a directory abstraction on top so you can browse and organize as folders. Files retain their original UUIDs in the Properties dialog.
- Upload: Two-stage commit through
/base/(multipart) followed by/files/{uuid}/storage/to flag the file as stored. Streaming progress with.aerotmpatomic semantics. - Download: Direct
https://ucarecdn.com/<uuid>/URLs with optional transformation paths. - Delete: Soft delete via REST. Files removed from listing but recoverable through the Uploadcare dashboard during the retention window.
- EU data residency: All data physically stored in EU regions (GDPR-compliant by default).
CLI
bash
aeroftp-cli ls --profile "MyUploadcare"
aeroftp-cli put --profile "MyUploadcare" ./assets/*.png /
aeroftp-cli get --profile "MyUploadcare" "/<uuid>" ./local/
aeroftp-cli sync --profile "MyUploadcare" ./media /Tips
- The public key is safe to embed in client-side code (signed upload widgets, etc.). The secret key must remain server-side. AeroFTP keeps both in the encrypted vault.
- Uploadcare's CDN supports image transformations via path segments (
/-/preview/300x300/, etc.). Append them to share links as needed. - Free tier includes 1 GB of stored media, 5 GB/month traffic, 1,000 operations/month, and a 500 MB max file size; check the dashboard for current pricing before production use.
- Activity Log surfaces the project public-key hostname in the clear (e.g.
Authenticated as api.uploadcare.com/<project>); the secret key remains masked.
Common Issues
| Problem | Cause | Solution |
|---|---|---|
401 Unauthorized | Wrong public/secret key pair | Regenerate the keys in the dashboard and reconnect. |
409 Conflict on delete | File still has active webhooks or pending operations | Wait for pending operations to settle, retry the delete. |
| Files visible in Uploadcare web but not in AeroFTP | Files are uploaded but not committed to storage | AeroFTP's put flow always commits. Check the dashboard's "Pending" filter for orphaned uploads. |
