Most converters ask you to upload the file first, which means a copy of your statement lands on someone else's disk, sits in a queue, and is trusted to be deleted later. That is privacy by policy, and a policy is only as good as the company keeping it.
A parser written in JavaScript running in your own tab has nowhere to upload to. The file is read locally and never crosses the network, so there is no copy to leak, no retention window to worry about, and nothing for a breach to expose.
