What happens to your file

It runs in this tab.

Your own browser does the work. Open the Network tab and watch it run: no request carries your file, and there is nothing on a server of ours to delete afterwards.

Type detection off by default, so 007 stays 007 and not 7.

  • No watermark The result is your file, unmarked. There is no paid tier that removes something we put there.
  • No account File Converter is exactly the same signed in or out. There is nothing to sign up for.
  • No ads, no waiting No banners, no upsell pop-up, and no invented thirty-second queue standing between you and your download.
  • Nothing to install It is a web page. The same one works on a phone: no app, no extension, no browser plugin.
  • What it reads CSV · TSV · JSON · YAML · YML · XML · MD. Anything it cannot read is turned down with a reason on screen, not a silent nothing.

Six questions

Questions

Is File Converter free?

Yes. Free, with no watermark, no account and no daily cap. It runs entirely in your browser, so there is nothing to meter.

Does my file get uploaded?

No. Everything happens in this browser tab, so the file never leaves your device. You can keep the Network tab open while it runs: no request carries your file.

Do I need an account?

No. This tool is exactly the same signed in or out.

Will it add a watermark?

No. The result is your file, unmarked. There is no paid tier that removes something we put there, because we do not put anything there.

Does it work on a phone?

Yes. It is the same web page, laid out for a small screen. Nothing to install, no app and no browser extension.

Are there ads, or a queue before the download?

No. No banners, no upsell pop-up, and no invented delay. When the job is done the file is ready.
