# n8n Binary and Data

Stop losing the attached file halfway through your workflow

## What this does

Your n8n workflow is carrying a PDF, an image or an upload, and somewhere along the way the file goes missing or the node cannot see it. This explains how files travel through a workflow separately from the regular data, and how to keep them intact. Reach for it any time a workflow touches files.

### Top 3 things it does for you

- Read and write files in a workflow
- Keep an attachment alive through a transform
- Hand a file to an AI agent as tool input

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About n8n Binary and Data

This is about handling files and binary data in n8n. It applies when you are working with files, images, PDFs, attachments, uploads or downloads, base64, or vision and multimodal input, and when an AI agent needs a file as input or output.

It covers the split between binary and JSON data, reading and writing binary, keeping binary alive across transforms including through Merge, the boundary where an agent tool receives a file, and the URL requirement for getting images into chat surfaces.

## Questions

### Is n8n Binary and Data safe to install?

AIR scanned this exact version of n8n Binary and Data and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 0a1fb9d46e27, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/n8n-binary-and-data.

### How do I install n8n Binary and Data?
