Sharing files made effortless
Trinsfer combines a 50 GB file transfer service with a Cloudflare-backed real-time speed test, an integrated dashboard, multi-language support and a public API — all under one roof.
Up to 50 GB per transfer
Send single files or whole folders, with resumable uploads powered by TUS. Pause, close the tab and resume hours later — your progress is safe.
Password-protected links
Add a password to any transfer and the recipient must enter it before any file is revealed. Combine with expiry dates for full peace of mind.
Flexible expiration
Pick 1 day, 7 days or — with Pro — up to a full year. Renew expired transfers within a 7-day grace period without re-uploading.
Built-in speed test
Measure download, upload, ping and jitter against Cloudflare's edge — and rate your connection for gaming, streaming and calls. Shareable score URLs included.
Dashboard analytics
Track downloads per transfer, see conversion rates, file-type breakdowns, growth trends and expiring-soon alerts — all in one place.
Smart notifications
Stay in the loop on uploads, downloads, expiring transfers and security alerts — categorised, grouped, and ringing only when it matters.
6 languages
English, Spanish, Portuguese, French, German and Italian — your interface preference is remembered across devices.
REST API
Upload, list, renew and delete transfers programmatically. Personal and team API keys with scoped permissions and per-minute rate limits.
Mobile-first
Drag-and-drop on desktop; full-screen optimised flows on phones. Works in any modern browser — no app install needed.
