Why they work like this

Most small web tools ask you to upload a file to a server you know nothing about. For a bank statement — which lists every place you shopped and every person who paid you — that is a strange thing to be asked, and an unnecessary one. A browser can do the work.

So these tools have no server to upload to. The page is a static file, the work happens in your tab, and the result is handed straight to your downloads folder. You can check it: open developer tools, watch the Network tab, and convert something.

Need a tool that doesn't exist yet? I build these one at a time, by hand. Tell me what you need.

This is a one-person workshop, not a company. If a file format is ruining your week, or one of these tools reads your bank's statement wrongly, say so — a real example is the most useful thing you can send me, and it is usually fixed within a few days.

This form sends only what you type. Your files are never part of it — they are never uploaded anywhere, which is the whole point of the tools.
