How to Convert Y4M Files to MP4?

Y4M, short for YUV4MPEG2, is a video file format often used in video processing and editing. It's uncompressed, which means it maintains high quality but also takes up a lot of space. While great for editing, it's not the most practical format for everyday use or sharing.

That's where MP4 comes in - a universal format that offers a good balance between quality and file size. The best compatibility makes it a go-to choice for many users. Now, let's get into the how-to part.

This tool is designed to make video and audio conversion a breeze, even for those who aren't tech wizards. Let's walk through the process step by step.
