Frequently asked questions

Are my video files uploaded anywhere?

These conversions run on our server, because they need ffmpeg, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.

Is converting video files free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

How large can my video files be?

Up to 1 GB per file. These conversions run on our server, which accepts files up to that size.

Does it work on my phone?

Yes. ConvertKitty runs in any modern web browser, on a computer or a phone, with nothing to install.
