How peeza works.

No upload. No cloud storage. No account needed to receive a link.
Here's what happens when you send a file.

How it works

Three steps, no upload.

Your file never waits on a server. It streams as soon as the other side connects.

1

Drop a file

Any size. It's read off disk in small chunks, so memory use stays flat from 4 MB to 400 GB.

2

Share a link or pick a device

A one-time link, one of your own machines, or a Peeza on the same network.

3

It streams across

Direct when the network allows it. Otherwise through a blind relay. Encrypted all the way.

Why peeza

Any file, any size, to anyone.

Privacy

No cloud storageFiles go machine to machine. They never sit on a server.
Always end-to-end encryptedAES-256-GCM per share. The relay forwards bytes it can't read.
One-time linksThe decryption key is in the link, not in our database (one exception).

Speed

Direct peer-to-peerStraight across when the network allows it.
Any size, constant memorySmall encrypted chunks. 400 GB uses no more memory than 4 MB.
ResumableLink and device-to-device transfers resume after a closed window, a restart or a reboot.

Convenience

Send to your own machinesOffice PC to home laptop. No cloud, no upload.
Nearby transfersTurn on Nearby to find Peezas on your local network. No relay, no internet, no login.
Web remote controlWatch and manage machines and transfers from the browser. In closed beta.
Security

Only you and the receiver can read your files.

If a transfer can't go direct, our server forwards encrypted data it has no key for. One exception: when you ask for it. You trust our servers in two places: the web page that decrypts in a browser and a new device's first key.

  • Each share gets its own AES-256-GCM key, made on your machine. It travels in the link fragment (#k=…). Browsers never send that part to a server.
  • The relay sees encrypted chunks, and the metadata it needs to route them (what it sees). It handles signaling and forwards bytes. It never decrypts.
  • Device-to-device sends use per-machine keypairs and sealed-key envelopes. The relay can't open the key it routes. A new device's first public key does come from the relay. Pairing in person removes that trust (why).
  • Nearby transfers confirm a first connection with a matching 6-digit code, then pin the peer.

How it compares

One hop, not a round trip.

WeTransfer, SwissTransfer and Dropbox upload your file to a server, keep it, then send it down. Peeza skips the server.

Everyone else

You a server, holding it Them upload, and wait then download

Peeza

You Them

One hop. They receive while you send. No upload wait, no size cap, no copy left on someone else's hard drive.

No direct path? Strict NATs and corporate firewalls can block one. Then a blind relay forwards the encrypted bytes and stores nothing. Direct transfers are never metered. Relayed traffic has a free monthly allowance with an account.

Terms change. In July 2025, WeTransfer briefly gave itself machine-learning rights over uploaded files. Two weeks of backlash reversed it. We can't read your files (within these limits), so there's nothing to grant.

FAQ

Common questions.

Is my privacy respected?

Yes. Files go device to device, end-to-end encrypted, and are never stored in the cloud. We can't read them, with one exception, when you ask for it. You trust our servers in two places: the web page that decrypts in a browser and a new device's first key. We do see metadata: IP addresses, sizes and timing. For a connected account, also file names in your dashboard and teams (what the relay sees). IP addresses stay in memory, never on disk, never logged. We use them to connect devices, to rate-limit, and for up to 15 minutes when you connect a new device. Details: privacy policy.

How secure is Peeza?

End-to-end, always. Each share gets its own AES-256-GCM key, made on your machine. It travels in the link, or sealed to the receiving device. We don't receive it (one exception, when you ask for it). If a transfer can't go peer-to-peer, our relay forwards encrypted bytes it has no key for. Details on the tech page.

Is there a file size limit?

No. Files stream off disk in small chunks. A photo and a video project of several hundred gigabytes work the same.

Do both sides need to be online at the same time?

For links, yes. The file goes straight from your machine to theirs, so both must be running. Sends to your own machines are queued and delivered when the target is back online.

When shouldn't I use Peeza?

For a link that stays up for a month: SwissTransfer. For a synced folder: Dropbox, or Resilio to stay peer-to-peer. Peeza gets a file to a person: fast, whole, no copy left behind.

How much does Peeza cost?

Free, no account needed. Direct transfers are never metered. Relayed traffic has a free monthly allowance with an account. Numbers on the relay page.

Why do some features need an account?

Sending a file needs no account. An account unlocks what needs to know who you are: sending to your own machines, the web remote control, and the free monthly relay allowance. We're not after your data. There's no Peeza password: you connect with Google, Microsoft, Apple or GitHub. We keep your email address and the devices you connect. If you use teams, also the teams and the names of files shared there (full list). Connected or not, your files stay end-to-end encrypted (within these limits).

Does Peeza work on Mac, Windows and Linux?

Yes, and it sends between them in any direction. iPhone, iPad and Android are on the way.

How is Peeza different from AirDrop?

AirDrop only works between Apple devices in the same room. Peeza works across Mac, Windows and Linux, over the internet or on your own network. On the same network it transfers directly, with no internet or account needed.

Who makes Peeza?

Me and a few friends, mostly me. I'm Eric, a recording and mixing engineer in Montreal, after three decades leading complex, secure software for enterprises. Peeza is four years of hard work and prototyping, sped up lately by advances in tech. Every way I had to send a session was miserable, so I built the one I wanted. And more :)
