# Sharing

> Turn a tool's state, or a saved chain, into a link

Two things on the site produce a link you can hand to someone else — both work without either side having an account.

## Copy a shareable link

A tool's "⋮" menu has a **Copy shareable link** item. It compresses your current input values into the tool's own URL and copies it — open that link and the tool fills in and runs automatically, landing straight on the result.

<Note>
  The state lives in the URL **fragment** (the part after `#`), which browsers never send to a server — so it never shows up in our logs, only in whoever's clipboard you paste it into.
</Note>

A few things never make it into the link, regardless of the tool: uploaded files, password-type fields, and any field a tool explicitly excludes from sharing. A link is capped at 1,800 characters' worth of compressed state — past that, **Copy shareable link** tells you it's too large instead of producing a broken link.

## Share a chain

A chain you've saved (see [Chains](/features/chains)) is private by default. Open "Your saved chains", hit **Share** on the one you want, and flip **Anyone with the link can view**. That gives you a link at `/chain/<shareSlug>/` — read-only, showing the chain's steps and an "open a copy in your own builder" option, but not editable by whoever you send it to.

Turn the toggle back off and the link stops working immediately.

## A specialized case: One-Time Link

The [One-Time Link tool](https://iotools.cloud/tool/one-time-link/) is its own catalog tool rather than a site-wide feature, but it's worth knowing about here: it encrypts a secret entirely in your browser and gives you a link that can only be opened once before it's destroyed — useful for handing off a password or API key somewhere less private than these two mechanisms.
