# Files and Images

> Attach documents and images and choose where they are parsed.

## Attaching Files

Use **Add photos & files** in the + menu, press C then U, drag files onto the composer, or paste them. Attachments ride with that prompt and are never stored on Nito's side.

* **Images** (PNG, JPEG, WebP) go to the model as images, so the model has to support vision. The browser resizes and strips metadata first: up to 10 images per turn, each up to 20 MiB, fitted within a 2048 px long edge.
* **Documents** (text, Markdown, code, PDF, DOCX, PPTX, XLSX, XLS) are converted to plain text before sending, so they work on any model.

If the selected model cannot read an attachment, the composer says so and offers to open the picker filtered to compatible models.

## Parser Mode

Each document chip shows a parser mode. The default is in Settings under **Attachment parsing**.

| Mode | What happens |
| :- | :- |
| **Client** | Parsed in your browser before anything is sent. |
| **Server** | Uploaded and parsed on the gateway; only the extracted text goes to the model. Nothing is stored. Required for formats the browser cannot parse. |
| **Auto** | Client for small browser-readable files, Server for larger ones and server-preferred formats. |

On an Encrypted chat, Auto is hidden and Client is the default. Choosing Server shows the warning **Server sees this file before encryption**. Raw image uploads are not sent on Encrypted routes yet.

## Free Plan

The free models today are text models, so attachments follow their capabilities. See [Free Usage](/plans/free-usage).
