# Files and Emoji

> Let visitors send screenshots and documents in the chat widget, and reply with files from your inbox.

## Overview

Visitors can attach a file to a chat message, or paste a screenshot straight into the
message box. Your team sees the files in the conversation and can reply with files of
their own. The message box also has a small set of common emoji.

## What visitors can send

* **Images**: PNG, JPEG, GIF and WebP. They show in the chat as pictures.
* **Documents**: PDF, Word, Excel, PowerPoint, text and CSV. They show as a card with the
  file's name, size and type.

Each file can be up to 10 MB, and a message can carry up to five. A message can be files
alone, with no text. The widget explains straight away when a file is too big, empty, or
a type it doesn't take, before anything is uploaded.

SVG, HTML and other files a browser could run are never accepted.

## In your inbox

A visitor's files show in the conversation the way an email's attachments do: pictures as
thumbnails you can open full size, and other files as chips that open in a new tab.

To reply with files, use the paperclip in the reply box, or paste a screenshot into it.
Each file uploads as soon as you add it, and **Send** waits until they're all up. A reply
can be files alone.

## Turning files off

Files are on unless you turn them off, in **Settings → Chat Widget → Settings → Features →
File attachments**. When it's off, visitors get no paperclip and a pasted file is ignored.
Your team can still reply with files. The live preview beside the setting shows the
change.

## Emoji

The smiley in the message box opens a small set of common emoji. The arrow keys move
through them, Enter picks one, and Esc closes the set. On a phone, the keyboard's own
emoji work as usual.

## Good to know

* Your AI agent can't open files. It sees which files a visitor attached and answers in
  its own words, and your team can open them in the inbox.
* Files count toward your workspace's storage. Files a visitor uploads but never sends
  are removed after a day.
* Files are deleted along with their conversation.
* Links to files are long and unguessable, and open without signing in, so they work
  from the visitor's chat and in your inbox alike.
