Frequently Asked Questions

What is an MP4 file?

MP4 is the most widely used video container format. It typically contains H.264 video and AAC audio, making it compatible with virtually every device, browser, and video platform. It offers excellent quality at reasonable file sizes.

Can I convert MP4 to MP3?

Yes. The MP4 to MP3 converter extracts the audio track from your video file. This is processed on the server using FFmpeg. Useful for saving music, podcasts, or lectures from video files.

How do I convert MOV to MP4?

Go to the MOV to MP4 converter page and upload your .mov file. MOV files from iPhones and Macs convert quickly to the more universally compatible MP4 format.

Can I convert MP4 to GIF?

Yes. The MP4 to GIF converter creates an animated GIF from your video. Note that GIF files are much larger than video and limited to 256 colors. Best for short clips under 10 seconds.
