Frequently Asked Questions

What does CNV MP4 mean?

CNV MP4 stands for "Convert MP4" - it's our brand name that clearly indicates our service's purpose: converting videos to MP4 format. CNV is an abbreviation for "Convert" and MP4 is the most popular and widely compatible video format.

Can I use this on Android phones?

Yes, you can use our service on Android phones with common browsers like Chrome, UC, etc. We recommend using Chrome browser for the best download experience.

Why doesn't the video download directly on iOS devices (iPhone, iPad, iPod)?

Since Safari and WeChat's built-in browser don't support direct file downloads, you'll need a third-party app. We recommend downloading the free "Documents 6" app from the App Store. Use our service through the Documents app's built-in browser for perfect video downloads. Documents also supports moving downloaded videos to your phone's gallery.

How can I download videos when using Internet Explorer?

Our service doesn't support Internet Explorer. For the best experience, we recommend using modern browsers like Google Chrome, Edge, or Firefox. If you must use a browser with limited download support, you can right-click the download button and select "Save Link As" or right-click the video and choose "Save Video As".

What should I do if the downloaded video won't play?

This rarely happens and is usually due to a file extension issue. Simply change the downloaded file's extension to .mp4, and it should play normally.
