Dropbox uploading slow? Skip the upload
Dropbox uploads at your upload speed, and if Custom bandwidth is turned on in its settings, it can go slower than that. The other person waits for the whole upload, and then they download the file again.
If the file is for one person, KEIBIDROP sends it straight from your computer to theirs. There's no upload step, no file size limit and no account, and they can open it while it's still coming in, even in a browser tab.
Check the bandwidth setting in Dropbox
Open the Dropbox desktop app and click your account icon, then Preferences, then the Network tab. If Custom bandwidth is on with a low upload rate, raise the limit or turn Custom bandwidth off, so Dropbox manages the speed itself.
Things that make a Dropbox upload faster
- Connect the computer to the router with a cable if it has a network port.
- Pause the other uploads on the same internet: camera uploads on your phone, iCloud, Google Drive and OneDrive.
- Zip a folder with lots of small files into one file first.
- Run a speed test and check the upload speed. At 10 Mbps up, a 5 GB video takes a bit over an hour to upload.
Send it straight to the other person
A Dropbox link means the file goes up to Dropbox first and then down to the other person. With KEIBIDROP it goes once, straight to their computer, and it shows up on their screen right away.
- Install KEIBIDROP from the install page. It's free for Mac, Windows and Linux, and there's an Android app too.
- Open it, press Copy next to your code, and send the code to the other person on WhatsApp, Signal, email or any chat app.
- They install it too, paste your code and press Add. Then they press Copy and send you their code. You paste theirs and press Add.
- You both press Connect.
- Drag the file or folder onto the window: a video, a PDF, a spreadsheet, an archive, a game, anything. It pops up on their screen and they press Save.
No install on their side? Press Invite link. They open it and press Join from this browser, then they can press Play on a video, View on a PDF, or Save.

Private the whole way
Everything is encrypted from one device to the other, and the encryption is quantum-safe: it's built to hold up even against future quantum computers. On a direct connection the file never touches our servers. When a firewall, a hotel Wi-Fi or a mobile network blocks a direct connection, our relay passes along encrypted pieces it can't read.
The key exchange combines ML-KEM-1024, a post-quantum algorithm in NIST's highest security category, with X25519, so both would have to be broken. Details on the security page.
Both computers have to be on and connected while the file moves. If you need to turn yours off, ask them to press Save first, so the whole file is on their computer.
For a file that several people need for months, a shared Dropbox folder still fits. For getting a big file to one person today, send it directly.
