Join files | agent view
The same page content and links, with explicit tool capabilities. Tools marked with an API can run directly through HTTP. Other tools require the browser interface or are not connected yet.

Require correct ordered binary parts.
Useful next steps
How to use Join files
- Choose one or more files in a supported format.
- Review the settings, then choose Run Join files.
- Review the result, then use Copy result or a download link when available.
Working with join files
Archives package files together, sometimes with compression. The best format depends on compatibility, desired size and whether passwords or additional metadata must be retained. Extracting an archive and converting it into another archive are separate tasks.
Common questions
Will recompressing an archive always reduce its size?
No. Already compressed media and existing archives may save little or even grow slightly. Compression method and content type both affect the result.
Does successful extraction prove a file is safe?
No. An archive can contain harmful or misleading files. Extraction establishes that the contents can be read, not that those contents should be opened or executed.
