Upnio - Upload Cloud
S3-Compatible File Uploads
Only for Mac
Free · In‑App Purchases
Mac
Upload files to your own object storage. Track transfers, handle large files, and create time-limited private download links.
Upload files directly to storage you configure.
Upnio is a native desktop client compatible with Amazon S3, Cloudflare R2, and custom S3-compatible endpoints. Add your own storage connection, choose or drag in files, and monitor each upload from one queue.
UPLOAD YOUR FILES
• Choose files or drag them into Upnio
• Run up to three uploads at the same time
• Pause, continue, retry, or cancel upload tasks
• View progress, transfer speed, and estimated time remaining
WORK WITH S3-COMPATIBLE STORAGE
• Configure AWS S3, Cloudflare R2, or a custom endpoint
• Test a connection before saving it
• Use path-style or virtual-hosted-style addressing for custom services
• Upload to the bucket root, date-based folders, or a custom prefix
• Choose whether duplicate names are overwritten or given a timestamp or unique ID
LARGE FILES AND UPLOAD HISTORY
• Files of 100 MB or more use multipart upload
• Search recent successful and failed uploads
• Copy or open an uploaded file link when a public URL is configured
• Generate a signed private download link that expires after 15 minutes, 1 hour, 1 day, or 7 days
UPLOAD COMPLETION OPTIONS
For each storage profile, Upnio can copy or open the uploaded link and show a local success or failure notification. Queue-level settings can notify you when all uploads finish, play a sound, or clear completed tasks.
YOUR STORAGE CREDENTIALS
Access keys and secret keys are stored in the system Keychain. Files are sent directly to the storage endpoint you configure; Upnio does not route uploads through a developer-operated upload server.
The free version supports one storage profile with the full upload workflow. A one-time Upnio Pro purchase unlocks unlimited storage profiles. Restore Purchases is available in Settings.
