Your files never leave your device
In short
Every FileInto converter runs inside your browser tab, on your own computer or phone. Your files are never uploaded, never stored on a server and never seen by us, and nothing about them reaches our servers: not their names, sizes or row counts.
How it works
When you open a converter, your browser downloads the converter's code once, like any web page. When you drop a file, that code reads it, shows you every row and writes the new file, all on your device. There is no upload step, so there is nothing for us to store, read or lose.
Our pages also tell your browser to refuse connections to any other website (a Content Security Policy). So the converter couldn't send your file to a third party even by mistake: the browser itself would block it.
Once the page has loaded, the conversion itself needs no internet connection. We tested it by switching off the server mid-session: a CSV still converted and downloaded.
What never happens
- Your file is never uploaded. Not to FileInto, not to a cloud service, not to an AI model.
- Nothing about your file reaches us. Not its name, its size or how many rows it has. Download limits are checked in your browser, not on our servers.
- Nothing from your file is stored. No transactions, payees, amounts, account numbers or file names.
- No person at FileInto can see your file. It never reaches us, so there is nothing to look at.
- Your data is never used to train AI and never sold. We run no ads and no ad trackers.
What our servers do handle
FileInto does use servers for the parts that have to be online, and none of them ever receive your files:
- The website itself: pages and converter code, served from Vercel.
- Accounts, for Day Pass and Unlimited customers: your email, your plan and your purchases. Nothing about your files.
- Payments, handled by Stripe through Link. We never see your card number.
- The plan check for Day Pass and Unlimited customers: once per visit, your browser asks whether your plan is still active. It sends nothing about your files. Download limits themselves are checked in your browser.
- Page view counts, with no cookies and no profile of you.
The full detail is in the privacy policy.
Check it yourself
You don't have to take our word for it. In Chrome, Edge or Firefox:
- Open a converter, for example CSV to QBO.
- Open the developer tools (F12, or Cmd + Option + I on a Mac) and choose the Network tab.
- Drop your file and download the result.
- Look through the list. While the file converts and downloads there are no requests at all, so nothing carries your file or anything about it. With a Day Pass or Unlimited you'll also see one request when the page opens, asking whether your plan is active; it carries nothing about your files.
- You can also switch off Wi-Fi after the page loads and convert a file anyway.

Questions
Is it safe to convert bank statements here?
Yes. A bank statement is exactly the kind of file that should not be uploaded. FileInto never receives it, so it can't be leaked, sold or seen by us.
What happens to the file after I close the tab?
It only ever existed in your browser's memory for that tab. Closing the tab clears it. The converted file is wherever you saved it.
