Frequently asked questions
Is it really free?
Yes. No signup, no API key, no payment.
Where do my files go?
Your file is uploaded over HTTPS, processed on our server, and the resulting HTML is sent back. All uploaded files are automatically deleted within 24 hours and we never share them with anyone.
Which formats are supported?
Microsoft PowerPoint .pptx (OOXML, the default since PowerPoint 2007). Older .ppt is not supported — open it in PowerPoint and save as .pptx first.
What is the file size limit?
Each file can be up to 100 MB. Files larger than that cannot be converted at this time.
What devices does it support?
Any modern browser on Windows, Mac, Linux, iOS, or Android. There is no app to install.
