⚡ Instant Share:Send files up to 2GB with zero signup & auto-expiry

File transfer, down to the chunk.

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

Every layer is visible, all the way down to one chunk.

Instant Ephemeral Sharing

Send files up to 2GB instantly with zero account or signup required. Features one-time download limits, password encryption, and auto self-destruction.

Resumable by design

Every upload is chunked and checksummed. Drop your connection mid-transfer and PushPort picks up at the last completed chunk — never the start.

Chunk-level retries

When one piece fails, only that piece retries. Watch retry counts climb on individual chunks instead of restarting the whole file.

Live speed telemetry

Real-time throughput, ETA, and per-session speed graphs so you know exactly when a 40GB dataset will actually land.

Provider-aware routing

Send files to Object Storage based on latency, cost, or your own policy — switch providers without re-uploading.

Controlled sharing

Password-protect links, cap download counts, set expirations. Revoke access instantly without touching the underlying file.

How a file actually moves

Four layers, one transfer.

01

Client SDK

Chunked uploads, 8MB segments, 4 parallel streams, exponential backoff

02

Transfer Engine

Session orchestration, chunk scheduling, checksum verification

03

Provider Adapters

Unified interface, swap without re-upload

04

Storage Layer

Object Storage

The transfer engine

See the chunk that's actually moving.

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

Trusted by teams who move a lot of data.

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.

Questions

Frequently asked

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.
