**Drag files into the composer, paste them, or choose "+" › Attach file to attach them before sending.**

Images, PDFs, documents, videos, and audio files are all supported — over 85 file types. Files appear as tiles in the composer and travel with your message when you send.

- Drag a file directly onto the composer or anywhere in the chat panel.
- Paste an image from the clipboard.
- On the web, click "+" in the composer and choose Attach file.

Where: Web: composer "+" menu › Attach file. Web and Mac: drag or paste into the composer.

Good to know: uploading a SKILL.md file installs it as a skill for that agent pod. The right panel previews images, PDFs, spreadsheets, videos, and audio. Files can be up to 50 GiB per upload.
