Microsoft Office 2013 Pro Plus is a powerhouse of productivity that stands the test of time. While searching for a link might seem like the quickest way to get started, always prioritize your digital security. Whether you choose to download, buy a key, or use a free alternative, Office 2013 remains a reliable choice for getting work done.

Many retailers sell legal, older "OEM" or "Volume" keys for Office 2013 at a very low cost. Conclusion

A full Office 2013 Pro Plus installer should be roughly 700MB to 900MB. If the file is only a few megabytes, it is likely a downloader containing adware.
