What a SteamID64 is

A 17-digit number and the format Steam itself uses everywhere internally. It is the account ID added to a fixed base of 76561197960265728, which is why every individual account's SteamID64 starts with 7656119.

Every endpoint of the Steam Web API takes this format, and it is what you see in a profile URL of the form steamcommunity.com/profiles/76561198012345678. If you are writing anything that talks to Steam programmatically, this is the format you store.

What a Steam Hex ID is

The SteamID64 written in base 16 rather than base 10. It carries exactly the same information — only the notation differs.

You mostly meet this one in log files, database dumps and a handful of older item and trading tools that stored IDs in hex. It is rarely what a service asks you for, and is usually something you need to convert away from.

Converting more than one ID

This page handles a single ID at a time. To convert a whole list at once — a ban file, an admin config, a spreadsheet column — use the bulk converter, which accepts mixed formats and custom profile URLs in the same paste.
