How to Convert MOV to MP4 Online (Free, No Software Needed)

If you use an iPhone or Mac, you are probably familiar with MOV files. MOV is Apple's default video format, and while it works perfectly in the Apple ecosystem, sharing MOV files with Windows users, Android users, or uploading to certain websites can be problematic. MP4 is the universal video format that works everywhere.

Why Convert MOV to MP4?

MOV files do not play natively on many Windows apps and Android devices. Many websites and social media platforms prefer or require MP4. MP4 files are often smaller than MOV for equivalent quality. MP4 with H.264 codec is the most widely supported video format in history.

How to Convert MOV to MP4 Online

The easiest method is using a browser-based converter. NowTo Tools' MOV to MP4 Converter processes your files entirely in the browser — no upload to any server, no software to install.

Steps: 1. Open the converter. 2. Drop your MOV file. 3. Select quality settings (high recommended for minimal quality loss). 4. Click Convert. 5. Download your MP4 file.

Does Converting MOV to MP4 Lose Quality?

With the right settings, quality loss is minimal to unnoticeable. If your MOV file already uses H.264 codec (common for iPhone videos), the conversion is essentially just repackaging the video data — the quality stays virtually identical.

Converting iPhone Videos

Recent iPhones record in either H.264 (most compatible) or HEVC/H.265 (higher efficiency). For maximum compatibility when sharing, convert to MP4 with H.264. The file size will be similar for H.264 sources or slightly larger for HEVC sources, but the compatibility gains are worth it.

Batch Conversion

Have multiple MOV files to convert? NowTo Tools supports batch conversion — upload all your files at once and convert them all with a single click. Each file is processed independently with optimal settings.

Alternative: Change iPhone Settings

You can prevent the problem entirely by changing your iPhone's camera settings. Go to Settings > Camera > Formats and select "Most Compatible." This records in H.264 MP4 directly, avoiding the need for conversion later.
