Beam

by UtubeMP3

Send a file from one phone to another — no app, no cloud, no account

Open this page on both phones, pick how you want to send, and the file goes straight from one device to the other. It is never uploaded to a server, so there is no size limit, no link that expires, and nothing left behind for anyone to find. Works between iPhone and Android, phone and laptop, or any two browsers.

Three ways to send

All three are the same idea — a direct device-to-device link — over three different physical channels. Pick by what you have, not by what sounds clever.

Wi‑Fi Beam

megabytes per second

Both devices on one Wi‑Fi or hotspot. Pair with a quick QR scan, then send whole videos in seconds. Use this one unless you can't.

Open Wi‑Fi Beam →

QR Beam

~3–10 KB per second

No network at all. One screen plays a stream of QR codes, the other films it. Good for a photo, a document or a password when there is no Wi‑Fi to join.

Open QR Beam →

Sound Beam

~0.4–1.5 KB per second

No network and no camera. The speaker sends the file to the other phone's microphone. Also exports a .wav you can send through any voice channel.

Which one should I use?

Your situationUseRoughly
Both phones on the same Wi-Fi, or one sharing a hotspotWi‑Fi BeamA 100 MB video in well under a minute
No Wi-Fi you can both join — a plane, a basement, someone else's officeQR BeamA 200 KB photo in about a minute
No network and the camera is unusable (cracked lens, glare, no permission)Sound BeamA short message or small photo in a minute or two
You want to send a file to yourself, phone to laptopWi‑Fi BeamSame as above — the laptop just scans with its webcam

How to send a file in three steps

  1. Open beam.utubemp3.net on both devices and tap the same mode on each.
  2. On the sending device, choose your files and tap the big button. On the other device, switch to the Receive tab.
  3. Point one camera at the other screen when it asks. The transfer starts on its own and tells you when it is done.

Nothing to sign up for and nothing to install — though you can add Beam to your home screen from your browser's menu, and it will keep working with no internet at all.

Why this is private by construction

Most "send a big file" sites upload your file to a company's server and give you a link. Beam has no server to upload to. The file crosses the room — over your own Wi-Fi, as light from a screen, or as sound in the air — and only the device in front of you ever holds a copy.

Questions

Does this work between an iPhone and an Android phone?

Yes. That is the main reason it exists — AirDrop only talks to Apple devices and Quick Share only to Android. Beam runs in the browser on both, so the two sides do not need to agree on anything except which mode to use.

Do I need to install an app?

No. It is a web page. If you want it on your home screen, use your browser's "Add to Home Screen" or "Install" option — that stores the page on your device so it also works with no internet connection, but it is still the same web page, not an app store download.

Is there a file size limit?

No limit is imposed. Nothing is uploaded, so there is no quota to hit. What actually limits you is speed: Wi-Fi Beam moves megabytes per second, so large videos are fine, while QR and Sound are best kept to photos and documents.

Does it work with no internet connection?

Yes, and that is the point of the QR and Sound modes — they use no network whatsoever. Wi-Fi Beam needs the two devices on one network, but that network does not need internet: a phone's personal hotspot with nothing behind it works fine. Load the page once and install it to your home screen, and Beam itself will open offline too.

Can someone else intercept my file?

Over Wi-Fi the connection is encrypted end to end with DTLS and pairing requires physically scanning a code off the other screen. QR and Sound are line-of-sight and earshot: anyone who could intercept them is standing next to you and can see your screen anyway. For those two, use judgement about who is in the room.

Why is it free? What's the catch?

There is no catch and no account. Beam is run by the people behind UtubeMP3 and is paid for by one sponsored link and the cross-promotion banners at the bottom of the page. Nothing about your transfer is sold, because nothing about your transfer ever reaches us.
