Drop files, prepare them in your browser and send them straight to another device. Peer to peer, no account, nothing kept on our servers
Your files go from your device to theirs, and nothing in between keeps a copy that's the point
No hopping between a converter, a compressor and a file host. The file you drop is the file you prepare is the file you send
Drag files in, paste from the clipboard or pick them from your device. They stay in this tab's memory and nothing is uploaded anywhere.
Compress a photo, convert its format, merge or split PDFs, turn a Word file into a PDF and bundle it all into a ZIP. Every tool runs in the browser.
You get a six character code, a link and a QR. The other browser opens it, connects to yours and the file streams across, encrypted in transit and verified on arrival.
Direct transfers are cut into 64 KB chunks and acknowledged one by one. Lost chunks are resent, damaged ones are re-requested by hash, and a transfer can pause and pick up where it stopped. When the last chunk lands, both sides get a receipt
Whichever you pick, the file goes from one browser straight to the other. There is no relay in the middle holding a copy
Across the internet. A STUN server helps the two browsers learn each other's address, and that is all it does. After that, the data channel runs between them alone.
Inside your network. Only local addresses are offered, and if the connection would leave the network, Clex stops rather than route it out.
Can't connect either way? Clex tells you instead of quietly uploading. Keep both tabs open until the transfer is done.
Flip the workspace to Vault for encrypted notes and secret links. Notes are encrypted before they touch your device's storage, sync only between devices you pair, and never appear on the public chain
Open the app and nearby devices on your network appear on their own. No codes, no pairing. The receiver taps accept and the file streams over the same verified Direct+ channel.
Every finished transfer prints a receipt you can keep, save as an image or send on: route, size, chunks, retries and a root hash, nothing about the file itself. The same record joins a public, hash linked chain, so anyone can check that a delivery happened
