MP4 Converter Questions I Answer Daily

"What videos can this MP4 converter handle?"

Everything. Seriously. AVI from 2005? Yep. MOV from your friend's iPhone? Obviously. That weird MKV file? No problem. This MP4 converter has handled every format I've thrown at it. Even converted a VOB from an old DVD last week.

"Does this MP4 converter ruin video quality?"

Nope. The converter keeps everything crispy by default. But if you need to shrink that 500MB video for WhatsApp, we've got compression options. Your choice: perfect quality or smaller files.

"Why does everyone want MP4?"

Because it just works. Your grandma's iPad? Plays MP4. That smart TV from 2015? MP4. Random Android phone? MP4. It's like the Swiss Army knife of video formats. This converter makes MP4s that work everywhere.

"How big can my videos be?"

Converted a 2.3GB wedding video yesterday. Took 3 minutes. The MP4 converter runs locally, so no upload limits. Your device does the work — got 8GB RAM? You're golden.

Why This MP4 Converter Exists (A True Story)

Three years ago, my client sent 47 MOV files from their iPhone. My Windows laptop laughed at them. Every \"free\" MP4 converter wanted my email, credit card, or soul. That's when I discovered browser-based conversion. Game changer.

Now I use this MP4 converter daily. Client sends MKV? Converter makes it MP4. Old AVI from 2003? MP4. Random format from that security camera? MP4. It's like having a universal translator for videos. Last week alone, I converted 200+ files for various projects. Still free. Still no watermarks.

Here's the secret: Your video never leaves your computer. This MP4 converter uses WebAssembly (fancy browser tech) to do everything locally. That confidential training video? Safe. Your kid's birthday party? Private. Upload speeds? Irrelevant. The converter just works, right in your browser. No catch. I'm as surprised as you are.
