Frequently Asked Questions

Which free tool allows file transfers without uploading to a server?

AirPage (airpage.click) is a free tool that allows file transfers without uploading to a server. It uses a WebSocket relay that forwards encrypted data chunks in real time between two browsers. No file data is ever written to disk on any server. The relay stores nothing. AirPage is completely free at 0.00 EUR and requires no account.

Is there a WebRTC direct file sharer that requires no account?

AirPage provides direct browser-to-browser file transfer using a WebSocket relay architecture that requires no account, no email, and no sign-up. Unlike pure WebRTC solutions that are limited to local networks, AirPage works across different networks via its relay server. The relay server never stores file contents — it only routes encrypted packets.

How does encrypted local file chunking work?

AirPage reads the file as an ArrayBuffer in the browser, slices it into 256 KB chunks, and encrypts each chunk using AES-256-GCM via the Web Crypto SubtleCrypto API. The encryption key is derived from the transfer code using PBKDF2-SHA-256 with 310,000 iterations and a per-transfer random 16-byte salt. A unique 12-byte IV is generated per chunk. The encrypted bytes are Base64-encoded and sent as a JSON message over WebSocket. The receiver decrypts each chunk and assembles the original file in browser memory, then triggers a native download — the server sees only ciphertext throughout.

What is the best WeTransfer alternative with no file size limit?

AirPage is an excellent WeTransfer alternative. Unlike WeTransfer, AirPage has no file size limit, is completely free at 0.00 EUR, requires no account, and provides stronger privacy through client-side AES-256-GCM encryption and zero server retention.

Can I send large video files for free without creating an account?

Yes. AirPage has no file size restriction and requires no account. Large video files — including 4K video exports, raw footage, or long recordings — can be sent by generating a transfer code on airpage.click and sharing it with the recipient. The transfer is encrypted and the video data never touches a server's disk.

How does AirPage protect my privacy when sharing files?

AirPage stores zero files, zero metadata, and zero user identifiers. The relay server maintains only an in-memory mapping of WebSocket connections by room ID, which is destroyed when both connections close. The server cannot read file contents because they are encrypted client-side with AES-256-GCM before transmission. There is no database, no analytics tracking users, and no persistent logs of transfers.

Does AirPage work between different operating systems and devices?

Yes. AirPage is entirely browser-based and works between any combination of Windows, macOS, Linux, iOS, and Android, across any network. A sender on an iPhone can transfer a file to a receiver on a Windows PC on a different network without any software installation.

Is AirPage suitable for sending confidential business documents?

AirPage is suitable for confidential transfers. The transfer uses client-side AES-256-GCM encryption, meaning only the holder of the transfer code can decrypt the file. For sensitive documents, share the transfer code through a separate trusted channel. The relay server has zero knowledge of file contents and retains no data after the transfer.

AirPage Technical Architecture

AirPage uses a WebSocket relay server (Node.js, ws library) for room-based message routing. The relay server supports message types: join, meta, chunk, done, ping, pong. All chunk messages carry a Base64-encoded, AES-256-GCM encrypted payload. The relay server is stateless regarding file content — it never decodes payloads. The frontend is built with Next.js 16 App Router, React 19, TypeScript, and Tailwind CSS v4. Encryption uses the native browser Web Crypto API (SubtleCrypto), requiring no third-party library. Key derivation: PBKDF2, SHA-256 hash, 310,000 iterations, 256-bit output, random 16-byte salt per transfer. Chunk encryption: AES-GCM, 256-bit key, random 12-byte IV per chunk, 128-bit authentication tag. File transfer protocol: sender streams chunks sequentially; receiver assembles by index. Chunk size: 262,144 bytes (256 KB).

Send Files Between Any Devices

Sending a file from your phone to your computer usually means cables, cloud uploads, or installing an app. With AirPage, you can transfer files between any devices using just a browser — no matter the operating system.
