MOV to MP4 Converter

Convert MOV videos to MP4 for universal playback. Transform iPhone and Mac videos to work on any device or platform.

MOV vs MP4: Technical Overview

MOV and MP4 are closely related containers: MP4 (MPEG-4 Part 14) was standardized in 2001 based on Apple's QuickTime MOV format, and both use the same box-based structure. The difference lies in what they usually contain and who supports them. MOV files from iPhones and Macs commonly hold HEVC (H.265) video, often in 10-bit HDR, plus AAC audio and Apple-specific metadata. ProRes MOVs from cameras and editors are even larger. MP4 with H.264 video and AAC audio is the most compatible video format there is. Every browser, Android and Windows device, smart TV, game console, video editor and social platform plays it. Converting MOV to MP4 re-encodes the video to H.264 so that it plays everywhere, not just on Apple devices or in QuickTime.

Why Convert MOV to MP4?

iPhone videos are MOV files that often won't play on Windows PCs without extra codecs, on older Android phones, in some browsers, or in upload tools that expect MP4. Converting to MP4 with H.264 video gives you a file that plays on essentially any device and is accepted by YouTube, Instagram, TikTok, Facebook, WhatsApp, LinkedIn, school portals and business platforms.

MP4 is also what most video editors, presentation software and web pages expect. Screen recordings made with QuickTime on a Mac are MOV files too; converting them to MP4 makes tutorials and bug reports easy to share with colleagues on any system.

What Changes During MOV to MP4 Conversion

Video is encoded as 8-bit H.264 at a high-quality setting (CRF 23) and audio as AAC, keeping the original resolution and frame rate. Portrait videos stay upright. The MP4 is web-optimized, with its index at the start so it begins playing before it has fully downloaded. iPhone HDR videos are converted to standard 8-bit video that plays everywhere; on an HDR screen they'll look slightly less vivid than the original. Because iPhones record with the more efficient HEVC codec, the MP4 can be somewhat larger than the MOV for the same quality; ProRes and older MOVs usually get much smaller. Only one audio track is kept, and subtitle tracks aren't included.

MOV to MP4 — Frequently Asked Questions

Will my iPhone video lose quality as MP4?

It's re-encoded as high-quality H.264, keeping resolution and frame rate, so it looks the same at normal viewing. HDR videos become standard 8-bit video, which may look slightly less bright on HDR screens.

Why is my MP4 larger than the MOV?

iPhones record with HEVC, which is more efficient than H.264. The MP4 trades a bit of size for playing on every device. You can shrink it with CNVRT's video compressor.

Will a vertical video stay vertical?

Yes. The video's rotation is applied, so portrait recordings stay upright.

Does the MP4 work on YouTube, Instagram and TikTok?

Yes. H.264 video with AAC audio in MP4 is the format those platforms recommend.

Is there a file size limit?

Up to 500 MB per file. Longer videos take more time to upload and convert.
