Clex connects preparation and delivery into a single flow. Here's exactly how it works, from first drop to final delivery.
Open Clex in your browser. Drag files in — images, PDFs, documents, anything. They stay in your browser's memory. Nothing gets uploaded to any server.
Use built-in tools to process your files before sharing. Compress images, merge PDFs, convert DOCX to PDF, bundle into ZIP. Chain operations together — one flows into the next.
Hit share. Clex scans the network, detects available routes, and picks the fastest path. Direct P2P is always tried first. Local network for same-Wi-Fi speed. Google Drive when direct isn't possible.
Clex Direct+ slices your files into 256 KB chunks, holds up to 32 in flight at once, and lets the receiver ACK each one. Lost chunks retry on backoff; corrupted ones get re-requested by hash. You can pause mid-transfer and pick up from the next pending chunk — no restart from byte zero. When the last chunk lands, both peers compute a content-free verified receipt: file count, total size, chunk count, retries, route, and an optional root hash you can copy.
Vault runs alongside the main workspace flow. Notes stay local, secret links carry their own policy, and timed Drive-share sessions clean themselves up.
Vault notes are encrypted in the browser, organized into folders, and available offline after the app loads. The local device remains the primary home for that content.
Secret Share lets you pick the expiry and decide which protections apply: view once, 60-second viewing window, no select, tab-switch lock, and DevTools guard.
Cloud Share uses Google Drive sign-in for ownership and quota tracking, accepts files up to 1 GB each, enforces a 10 GB daily budget, and removes the Drive session after 24 hours.
After Clex loads once, the preparation tools work completely offline. Compress images, merge PDFs, convert documents — all without internet. Share when you reconnect.
Local network transfer handles large files at LAN speed. For remote transfers, P2P streams chunks progressively. Drive has Google's file limits for the fallback path.
Clex automatically detects when direct P2P can't establish. It offers local network or Google Drive as alternatives. You choose — Clex never switches without asking.
Chrome, Firefox, Safari, Edge — any modern browser with WebRTC support. Mobile browsers work too. Clex adapts the interface to your screen size automatically.
