PushPort resumes every upload exactly where it stopped, retries only the piece that failed, and shows you precisely which chunk is in flight.
Drag and drop any file here to test-drive magic byte verification & streaming chunk grids instantly.
Built for transfer, not storage
Send files up to 2GB instantly with zero account or signup required. Features one-time download limits, password encryption, and auto self-destruction.
Every upload is chunked and checksummed. Drop your connection mid-transfer and PushPort picks up at the last completed chunk — never the start.
When one piece fails, only that piece retries. Watch retry counts climb on individual chunks instead of restarting the whole file.
Real-time throughput, ETA, and per-session speed graphs so you know exactly when a 40GB dataset will actually land.
Send files to Object Storage based on latency, cost, or your own policy — switch providers without re-uploading.
Password-protect links, cap download counts, set expirations. Revoke access instantly without touching the underlying file.
How a file actually moves
Chunked uploads, 8MB segments, 4 parallel streams, exponential backoff
Session orchestration, chunk scheduling, checksum verification
Unified interface, swap without re-upload
Object Storage
The transfer engine
Most tools show you a percentage. PushPort shows you the grid: which chunks landed, which one is in flight, which one is retrying after a timeout, and which one needs your attention.
From engineering teams
“We moved our model training datasets off a homegrown rsync script. Retries that used to mean re-uploading 400GB now resolve in seconds.”
Priya Sharma
Platform Engineering Lead
“The chunk visualizer sounds like a gimmick until your transfer fails at 94% and you can see exactly which piece to retry.”
Daniel Cohen
Site Reliability Engineer
“Switching our backups from S3 to local storage took an afternoon, not a migration project. No re-uploads required.”

Infrastructure Architect
Questions
PushPort tracks completion at the chunk level, not the file level. When you reconnect, the transfer resumes from the last completed chunk — nothing already uploaded gets sent again.
Yes. Files can be replicated or moved across Object Storage without re-uploading from your machine — PushPort transfers between storage targets directly.
Yes. There is a maximum file upload cap of 100MB per file and a total storage quota limit of 1GB per user to maintain high-performance and availability.
Yes. To prevent abuse and ensure fair resource sharing, API endpoints are rate limited. If you exceed the rate limits, requests will temporarily return a 429 status code.
Each chunk has its own retry counter and backoff schedule. A failure on one chunk never restarts the rest of the transfer; you can see retry counts per chunk in the transfer detail view.
Links can require a password, expire on a schedule, and cap total downloads. Revoking a link takes effect immediately and doesn't touch the underlying file.
No credit card. Connect a storage provider and run your first transfer in minutes.
