> ## Agent Instructions
> Spreader is a web service that tracks arbitrage spreads between crypto exchanges. This documentation covers only what a user of the service sees and does.
> Page paths starting with /en/ are English. Translations live under /ru/ and /uk/ with the same file names.
> Screenshots are illustrations. Every screenshot is accompanied by text that states the same facts, so you do not need to see the image.

# Share a spread

> The Share button renders a PNG card of the spread with the main value, legs with prices, APR, funding, time and a QR code, to copy, download or send, plus a link to the page.

**Share** in the spread page header opens a panel with a preview of the image. The image is always drawn in the Spreader dark style, whatever the site theme, and its texts are English.

| **Copy image** | Copies the PNG to the clipboard. The status shows `Image copied · W × H`. |
| **Download PNG** | Saves the file. |
| **Share…** | Opens the system share sheet with the image, on phones and in browsers that support it. If the browser shares links only, the panel says so. |
