How to Share a Private Video

SpectrShare actually started life as a way specifically to share private videos - I still have the url privatevideosharing.com pointing to SpectrShare because that was the first name of the site. Just because the name changed, doesn't mean the problem has - you have a video you want to share with someone specific. Maybe it's a family moment, a work presentation, or, let's be real here, maybe some "NSFW" content. You don't want it sitting on someone else's server, and you don't want to create yet another account somewhere.

Most "private" sharing options aren't really private. An unlisted YouTube link is still hosted on Google's infrastructure. A Google Drive or Dropbox link means uploading the full file to their servers, where it lives until you remember to delete it. Even emailing lives on other peoples servers. In every case, a copy of your video exists on hardware you don't control.

There's a simpler approach: send it directly from your browser to theirs.

The whole process takes about 30 seconds:

1. Go to spectrshare.com/share and drop your video file (or any file...) onto the page. You can also click to browse, or drop an entire folder if you're sharing multiple files.
2. Set a password. This is optional but I'd recommend it. A share link on its own is already hard/practically impossible to guess, but adding a password means that even if someone intercepts the link, they can't access your video without knowing the password too. Even site admins at SpectrShare can't connect without knowing the password, and that password is never sent to our servers. Share the password through a different channel than the link - if you send the link over email, text the password, or vice versa, to make it harder for an attacker to intercept.
3. Click Share and you'll get a link and QR code. Send the link to your recipient however you like.
4. Your recipient opens the link, enters the password if you set one, and can download the video immediately. No account, no sign-up, no app install. They can even stream the video without having to download the full file once your browser completes the file conversion.

That's it. Your video transfers directly from your browser to theirs over an encrypted peer-to-peer connection. No server ever stores a copy.

When you share a file through SpectrShare, the data travels directly between browsers using WebRTC. The signaling server helps the two browsers find each other, but the video data itself never touches it. There's no upload step, no cloud storage, no CDN.

Close the tab and the share is gone. There's nothing to delete later because nothing was stored in the first place. If you're curious about the philosophy behind this, I wrote more about it in Why No Cloud?.

The peer-to-peer connection is encrypted by default (DTLS), so the data is protected in transit. Adding a password on top means recipients need to prove they're authorized before the connection will send anything.

Raw video files can be huge. A 10-minute 4K clip might be several gigabytes, and downloading that before watching isn't ideal.

If you toggle on video conversion in the share settings, SpectrShare will convert your video in the background right in your browser. Your recipient can then stream it with a YouTube-like player - seek, pause, pick a quality level - all while it transfers peer-to-peer. The conversion happens locally on your machine. Still no server involved. There's a deeper look at how the video streaming works if you're interested in the technical side.

For shorter clips or when you don't need streaming, recipients can just download the original file directly.

• Always set a password for anything sensitive. The share link is random and practically unguessable, but a password adds a second layer.
• Share the password out of band. If you email the link, send the password over Signal or a text message. If someone compromises one channel, they still can't access the video.
• Keep your browser tab open. Since there's no server copy, the share only works while your browser is open and connected. Once you close the tab, new recipients can't access it and the video is no longer shared.
• Use the latest version of Chrome, Edge, or other Chromium based browser for the strongest WebRTC encryption and best performance. Not sure if your setup is compatible? Test your connection.
