Frequently asked questions

Is it safe to convert my files here?

Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.

Is it free? Are there limits?

It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.

Can I convert many spreadsheets & data files at once?

Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
