Send a PDF with a link nobody else can open — not even Bindery
AES-256 sealed on your device; the key travels in the link fragment, expiry and download caps built in.
Send PDF securely now — free →Most “secure share” links are just links to a server that holds your file in the clear. Bindery seals the PDF in your browser with a fresh AES-256-GCM key, uploads only the sealed package, and puts the key after the # in the link — the part of a URL browsers never send to any server. Bindery’s storage holds bytes it cannot decrypt, not even the file name.
Links expire (1, 7 or 30 days) and stop after a chosen number of downloads; the package is deleted when either limit is reached. Recipients open the link in any browser, the file is decrypted on their device and lands straight in Bindery’s tools. Creating links needs an account; opening them does not. Bindery runs entirely in your browser — your file is never uploaded, so there is nothing to delete from a server afterwards.
How it works
- Drop the PDF and open Secure handoff (or use “Send with a secure link” on any result)
- Pick the expiry and download limit — the file is sealed and uploaded as ciphertext
- Copy the link and send it by whatever channel you trust
Questions people ask
What can Bindery see?
A sealed package, its size, when it expires and how often it was fetched. The key is never sent to Bindery — it lives only in the link fragment — so neither the document nor its name is readable server-side.
What if the link leaks?
Anyone with the full link can open the file until it expires or the download limit is reached — the same as with any link; that is why both limits exist and default to 7 days and 10 downloads. Use 1 download for the strictest handoff.
Does the recipient need an account?
No. The link opens in any modern browser and the file is decrypted there; an account is only needed to create links.
