| Upload | Opens as |
| --- | --- |
| Code and text (about 70 languages) | Highlighted in your [code theme](/settings), with line links like `#L12` |
| Markdown | A rendered document; frontmatter shows as a properties list |
| HTML | The page, running in a sandboxed frame |
| CSV and TSV | A table with sticky headers |
| SVG | An image, rendered in a sandbox |
| Images | A centred preview |
| Video and audio | A player that seeks by byte range |
| PDF | The browser's PDF viewer |
| Zips and folders | A [share page](/share-pages) |
| [Scrawl](https://scrawl.kitlangton.com) captures | A [recording page](/scrawl) |
| Anything else | A download page |

Markdown, HTML, CSV and SVG have a **Source** view at `?view=source`. Every drop's raw bytes are at `/<slug>/<filename>`, with `?download=1` to force a download. Raw HTML and SVG are always served as plain text or in a sandbox, so a drop can never run script on your domain.

The `...` button in the top-right holds every action for a file. Right-click anywhere for the same actions as a pie menu.
