No signup, no install, no configuration. Follow these steps and you'll be sharing files before you finish your coffee.
Click "Open Workspace" from anywhere on the site, or go directly to the workspace URL. No account needed — it opens instantly in your browser.
Drag files from your desktop, file explorer, or another browser tab into the workspace drop zone. You can also click the zone to browse and select files. PDFs, images, documents, ZIPs — anything goes.
Need to compress an image? Merge PDFs? Convert DOCX to PDF? Use the built-in tools. They appear automatically based on your file types. Each operation happens in your browser — nothing gets sent anywhere.
Click "Share" and Clex generates a unique 6-character code. Send it to the recipient — they open it in their browser and the transfer begins. Clex automatically tries direct P2P first, then local network, then Google Drive as fallback.
Direct+ shows a live progress bar, a chunk rail, and a health card with route, retries, and verified count. You can pause mid-transfer and pick back up where you left off — the chunk tracker remembers what's already verified, so resume doesn't restart from byte zero. When the receiver finishes, both sides get a verified receipt with file count, size, chunk count, and an optional proof root hash.
Got a Clex code? Open the workspace, click Receive, type it in. The transfer starts automatically, the receiver verifies each chunk against the manifest, and the file lands in your browser. No app install, no login.
Use Vault when the job is private notes, controlled secrets, or a timed Drive-share link instead of a live transfer session.
Go to the Vault page from the main navigation. Notes open instantly in the browser, and you can switch between Notes, Secret Share, Cloud Share, and Settings from the same shell.
Write encrypted notes locally, or paste sensitive text into Secret Share and choose how long the link should live before it expires.
View once, 60-second viewing window, no select, tab-switch lock, and DevTools guard are optional. If view once stays off, the recipient can reopen the link until it expires.
Sign in with Google, upload files up to 10 MB each, and send the timed link or QR code. Vault keeps the daily relay budget at 100 MB and deletes each relay file after 24 hours.
Select multiple images and compress them all at once. The tool applies the same settings to every file, saving time on repetitive work.
After compressing, the output automatically becomes available for the next tool. No need to download and re-upload between operations.
Once Clex loads, the preparation tools work offline. Perfect for working on a flight or in areas with spotty connection. Share when you're back online.
Transferring to someone on the same Wi-Fi? Clex detects this and uses local network transfer for maximum speed. Great for large files.
When direct transfer isn't possible (different networks, NAT issues), Clex can use Google Drive as a secure relay. Files go to your Drive, not Clex's servers.
For P2P and local transfers, files exist only in browser memory during the transfer. When you close the tab, they're gone. Zero server-side storage.
Direct+ lets you pause an in-flight transfer and resume from the next pending chunk — no restart, no double-sending. Useful for slow networks, mid-call interruptions, or simply switching to a faster window.
Every Direct+ transfer ends with a content-free receipt: chunks, retries, route, health score, and an optional root hash. Click to copy and keep a record without exposing what was sent.
Need to drive transfers from a terminal or a script? The HTTP API handles room metadata, health, and (planned) status / pause / resume / receipt endpoints. See Developers.
