Questions

Why save as PPT?

Only for PowerPoint 2003 or older. Everything since 2007 opens PPTX.

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.

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.
