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).

Frequently Asked Questions

Everything you need to know about sending files with AirPage.

What is AirPage?

AirPage is a free browser-based tool that lets you send files directly between devices using peer-to-peer technology. No accounts, no cloud storage, no signup — just instant encrypted file transfer.

Do I need to create an account?

No. AirPage requires zero registration. Simply open the website in your browser, drop a file, share the generated code, and your recipient downloads instantly.

Is there a file size limit?

No. There are no artificial file size limits. You can send files of any size — the only constraint is your internet connection speed.

Is AirPage secure?

Yes. All file transfers are encrypted using AES-256-GCM with a key derived from your transfer code using PBKDF2. Files stream directly between browsers and are never stored on any server.

How does AirPage work?

AirPage creates a private room identified by a unique three-word keyword. The sender drops a file, the receiver enters the same keyword, and the file streams directly between them in encrypted 64 KB chunks.

Are my files stored on a server?

No. Files are transferred in real-time directly between browsers. Data never touches a server disk — the relay server forwards encrypted packets and forgets them immediately.

What browsers does AirPage support?

AirPage works on any modern browser including Chrome, Safari, Firefox, and Edge on desktop and mobile.

Can I send files from my phone?

Yes. AirPage is fully responsive and works on mobile browsers. You can send files from your phone to any other device.

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

Yes. Since files transfer directly between browsers in real-time, both the sender and receiver need to have AirPage open simultaneously.

Is AirPage really free?

Yes, AirPage is 100% free to use. There are no hidden charges, premium tiers, or usage limits.

What is P2P file transfer?

P2P (peer-to-peer) file transfer sends data directly between two devices without going through a central server. This makes transfers faster and more private than traditional cloud uploads.

How fast is the transfer?

Transfer speed depends on your internet connection. Since files go directly between browsers, the speed is limited only by the slower of the two connections — typically the sender's upload speed.

Can I send multiple files?

Yes. You can select and send multiple files. For folders, we recommend zipping them first for smoother transfer.

What kind of files can I send?

Any file type is supported — documents (PDF, Word, Excel), images (JPG, PNG, RAW), videos (MP4, MOV, AVI), archives (ZIP, RAR), and more.

How is AirPage different from WeTransfer?

WeTransfer requires uploading files to their cloud servers. AirPage transfers files directly between browsers with no intermediate storage, no accounts, and no file size limits.

Does AirPage track me?

No. AirPage does not use tracking cookies, analytics, or collect personal data. Your privacy is built into the design.

What happens if the transfer is interrupted?

If the connection drops, the transfer stops. Since data isn't stored on any server, you would need to start a new transfer session.

Can I use AirPage for business?

Yes. AirPage is ideal for sending large files to clients, sharing design assets with remote teams, or transferring confidential documents securely.

Why does the transfer code have three words?

AirPage uses a three-word keyword system (like 'sigma-pulse-pulse') that is easy to read aloud, type, and remember — much easier than a long URL or random string.

What encryption does AirPage use?

AirPage uses AES-256-GCM encryption. The encryption key is derived from your transfer code using PBKDF2 with 100,000 iterations of SHA-256.
