Questions and answers
Is Convert Office formats really free?
Yes. There is no charge, no account and no limit on how many files you convert.
Are my files uploaded anywhere?
No. The conversion runs inside your browser, on your own device. Your files are never sent to us or to anyone else.
Is there a file-size limit?
There is no fixed limit. Very large files depend on how much memory your device has; a computer copes with more than a phone.
Does it work without an internet connection?
Yes, once you have opened the tool while online. You can also save the whole site for offline use from the home page.
Why is there a large download the first time?
Word, Excel and PowerPoint files are converted by a complete office engine running in your browser. It is about 84 MB, downloaded once and then kept by your browser.
