How to use Convert office file

  1. Open your Word, PowerPoint, OpenDocument or Pages files.

  2. Choose what to save them as. Documents stay documents and slideshows stay slideshows.

  3. Press Convert. The first time, the office engine downloads once (about 77 MB); after that it starts from your device.

Questions

How does this work without uploading?

It runs LibreOffice, the free office suite, inside your browser. The engine is downloaded from this site once and kept on your device, and your files are converted right there.

Why is the first conversion slow?

The office engine is large (about 77 MB), so the first time it has to download and start, which takes a little while on a slow connection. Later conversions start in about 10 seconds.

Does it work on phones?

It works best on a computer. Phones and tablets with plenty of memory can run it, but some older ones run out of memory with an engine this size.

I need a PDF.

Turning documents and slides into PDF is done on our sister site Think PAGES.

Are my files uploaded?

No. Everything happens inside your browser, on your own device. The site's security settings stop the page from sending your files anywhere.

Is it free?

Yes. No sign-up, no daily limit and no watermark.

Does it work on iPhone and Android?

Yes, in Safari, Chrome and other modern browsers. You can open files from the Files app or your downloads, and save the results back.

Know someone who'd find this handy?

Send the link to a friend or colleague. It's free for them too, with no sign-up.

Other converters upload your files. This one can't.

Customer lists, contacts, bank exports and the routes you run from home stay on your phone or computer from start to finish.
