MOV is Apple's QuickTime video format, introduced in 1991 as one of the first multimedia container formats. It's the default format for iPhones, iPads, and macOS screen recordings. MOV files are often extremely large because Apple devices record in high-quality codecs like ProRes, HEVC, or uncompressed formats designed for professional editing.
MOV files tend to be very large (prores) compared to optimized MP4. Converting from MOV to MP4 H.264 typically reduces file size by 40-80% while maintaining excellent visual quality. The resulting MP4 also plays on every device and platform without compatibility issues.
MOV was developed by Apple in 1991. It uses the QuickTime File Format container and typically contains ProRes/H.264/HEVC encoded video. Browser support is safari full, chrome/firefox partial, and mobile support is ios native, android varies. For streaming, MOV offers limited capabilities.
Keep MOV if you're doing professional editing and need the original codec quality. Convert to MP4 when: you need to share the video online, upload to social media, send via email, or reduce storage usage. For 99% of sharing and consumption purposes, MP4 is the better format.

When you upload a MOV file, SquishVideo first analyzes the video stream to understand its codec, resolution, framerate, and bitrate profile. We then transcode the video to H.264 MP4 using optimized encoding parameters. The entire process preserves audio quality (re-encoded to AAC) and maintains the original resolution unless a lower resolution would provide a better quality-to-size ratio.
MOV files typically come from: iPhones, iPads, macOS QuickTime, Final Cut Pro exports, and professional cameras.
