How do I put the file back together?

Use the Join Split Files tool, adding every part it produced.

Can I rename the parts?

No — the part number and total count are encoded in the file name, so Join Split Files can reassemble them in the right order. Renaming a part breaks that.

Does this tool upload my file anywhere?

No — splitting runs entirely in your browser.
