Instant sharing · temporary · no sign-up
Any file.
Shared in seconds.
Drop a file — or several, or paste one straight from the clipboard — and get back a clean short link and a QR code. The file rides a temporary host and expires exactly when you said it should, one hour to three days later. Lock a share with a password if it matters.
No account, no tracking, and labs.llc never keeps the file: uploads pass through this site’s own endpoint to Litterbox’s temporary hosting, and all that stays here is the tiny mapping that makes the short link short. For genuinely sensitive material, use end-to-end encryption instead — this page will tell you the same.

The drop
In goes a file. Out comes a link.
Several files queue and upload one after another. The link expires on the schedule you pick — and the choice is remembered for next time.
The drop
Whoever opens the link is asked for it before the file moves. Generate mints a strong one and copies it.
Uploading…
The file is travelling through this site’s own endpoint to the temporary host.
Kept in this browser only, eight at most, and swept after a week — by then every link in it has long expired anyway.
How it works
Three steps, honestly told.
01
Drop
Drop, browse or paste any file up to 2.24 GB — big ones travel as parts and reassemble on the way down — pick how long the link should live, lock it with a password, encrypt it in the browser, or set it to burn after its first download.
02
Carry
The file travels through this site’s own endpoint to Litterbox, a temporary host built for exactly this. labs.llc never stores the file — only the few bytes that map the short code to where it went.
03
Share
You get a clean /f/ short link on this
domain and a QR code that carries it. Anyone who opens it is
redirected to the file — through the password gate first, if
you set one — until the clock runs out and the link dies.
The desk
The service, examined.
The same health endpoint the operators read, offered to you: whether the temporary host is answering, how many links are alive right now, and how long the check took. Read on demand — it spends a request.
Health
Nothing read yet — the desk answers when asked.
About
Temporary, and honest about it.
The file.com.im instant-sharing engine, brought home to labs.llc and rebuilt on the paper system in both editions — the queue, the passwords, the branded short links, the QR codes, the history and the health desk all survive. The files themselves live briefly on Litterbox’s infrastructure and are deleted on schedule; the short-link mappings live here and are pruned as they lapse. Sent plain, nothing about this flow is end-to-end encrypted. Tick Encrypt in the browser and it is: the file is sealed with AES-GCM here, before it leaves, and the key rides only in the link’s #fragment, which browsers never send to a server — so neither labs.llc nor the host can read it. Anyone holding that whole link can, so treat it as the secret it is. For everything else — a link in seconds.
