# DragBin Send — Send Large Files Free, 100 GB, End-to-End Encrypted Double-click to send a file Hold to send a folder Choose a file-Choose a folder-or drop anywhere Files here vanish in 24 h. [Keep them for good with DragBin](https://app.dragbin.com/signup), 25 GB free. [How it works ](#details) # Send large files free, end-to-end encrypted DragBin Send moves a file or a whole folder, up to 100 GB, without an account. It's encrypted in your browser before a single byte leaves it; the key lives only in the link you share. Uploads resume, links can carry a password, and every transfer is deleted after 24 hours. - 01 ## Encrypted before upload A fresh AES-256 key per transfer, generated in your browser. Filename and contents are ciphertext on our side; the key travels only in the link fragment. - 02 ## Resumable, straight to storage Files go up in 16 MB parts directly to object storage. Folders are packed into one zip first, in your browser. Drop offline, reload, come back: it continues from the last finished part. - 03 ## Gone in 24 hours Every transfer is deleted 24 hours after upload, full stop. Delete earlier from this page whenever you like. ## How do we know it's you? You don't need an account. When you upload, this browser keeps a private owner key for each transfer in its own local storage. That key is what lets you see the download count and delete early; nobody else can. It only works in this browser on this device. Clear your site data or switch devices and the list disappears (the files still self-destruct after 24 hours). Want your transfers everywhere, forever? [That's what a DragBin account is for](https://app.dragbin.com/signup). ## Questions ### Is it really end-to-end encrypted? Yes. Your browser generates a random 256-bit key, encrypts the file with AES-256-GCM in 1 MB frames, and uploads only ciphertext. The key is placed in the part of the link after the #, which browsers never send to any server, so we can't read your file, your filename, or the key. ### How long do files stay available? 24 hours from upload, then the file is deleted from our storage: no extensions, no exceptions. If you need files that stay, that's what a DragBin account is for. ### What's the size limit? 100 GB per transfer and 100 GB per day per network. A folder is packed into one zip in your browser (no compression, so it's fast) before it's encrypted. Uploads resume if your connection drops or you reload the page. ### Do I need an account? No. This browser remembers the transfers you created (locally, in its own storage) so you can copy the link again, see the download count, or delete early. Clear your site data or switch devices and that list is gone; the files still self-destruct after 24 hours. ### Can I protect the link with a password? Yes, even while the upload is running. The password wraps the encryption key inside the link itself; it's checked in the recipient's browser, never sent to us. A wrong password simply fails to decrypt. ### What if the recipient's browser can't handle a 50 GB download? Chromium browsers (Chrome, Edge, Brave) on desktop stream straight to disk with no size limit. Firefox and Safari stream through a service worker. Phones and very old browsers can only handle files under 1 GB in memory; the page tells the recipient which it is. ## Need files that don't expire? DragBin Send is for one-off transfers that vanish in 24 hours.
