Although iMovie supports exporting to MP4, if you are seeking lossless quality, batch conversion, or to resolve compatibility issues, using professional desktop software like AnyMP4 Video Converter Ultimate is the safest and most efficient option. When you finish editing in iMovie, the exported file is saved in MOV format by default. However, MOV is not always fully compatible on different devices, players, or editing platforms. On the other hand, MP4 is a more universal digital video format. It is widely used for storing video, audio, and even images in a compressed but highly compatible form.
This post shows you how to export iMovie to MP4 directly in the iMovie app. We will also teach you how to convert iMovie to MP4 in lossless quality, in batch mode. This way, you can easily share, play, and edit your videos into other programs.

Before using other tools, it is worth knowing that you can export iMovie to MP4 directly. By default, iMovie saves the video project in MOV format. A small configuration change in the export settings can help you save iMovie projects as MP4s instead of MOVs.
1. Share iMovie File
After editing a video in iMovie, click the Share button and select the Export File option. This option also applies when opening an existing video project in iMovie. In addition, you can share videos directly in email, save a current frame, or share on social platforms.
2. Edit Export Information
After clicking the Export File option, the File window opens. Adjust the export details, such as Title, Description, Tags, Format, Resolution, Quality, and Compress settings. To save iMovie as MP4, do not select Best (ProRes), as it will save the project in MOV format.
For your reference:
Format: Video and Audio
Resolution: 720p 60
Quality: High or Custom
Compress: Faster
3. Export iMovie to MP4
Click the Next button to proceed. In the Where field, choose a folder on your Mac where you want to save the MP4 file. Click Start to begin exporting your MP4 file. You can check the progress bar in the upper-right navigation to monitor your estimated wait time.
This method is the easiest way to convert existing iMovie MOV files to MP4. With the correct export quality setting, you can convert iMovie to the MP4 format. If you want more control over quality and batch conversion, a dedicated video converter is a better solution.
Many users assume that iMovie always exports videos as MOV files, but that is not always true. The most common mistake is selecting Best (ProRes) in the export settings. When this option is enabled, iMovie saves the video as an MOV file rather than an MP4.
To avoid this, choose Low, Medium, High, or Custom under the Quality settings when exporting. These options create an MP4 file that is easier to share, upload, and play on different platforms. If an MOV file has already been exported, there is no need to recreate the entire project.

Q: Why is iMovie exporting as MOV instead of MP4 in 2026?
A: iMovie exports videos as MP4 when you use standard quality settings. However, if you select Best (ProRes) during export, iMovie creates an MOV file instead. This happens because ProRes is Apple's professional video codec, designed for high-quality editing.
Q: How to change iMovie to MP4 on iPhone or iPad without a computer?
A: On iPhone or iPad, iMovie exports videos in an MP4-compatible format using the H.264 codec. To save a video, tap Share and select Save Video. If the exported file appears as MOV, it is because iOS labels videos with the MOV container even when they use MP4-compatible codecs.
Q: What are the best iMovie export settings for high-quality YouTube uploads?
A: For YouTube, 1080p or 4K resolution, High Quality, and the original 30 FPS or 60 FPS frame rate provide the best results. Avoid lowering the quality or using excessive compression. If the original footage looks soft or lacks detail, you can use AnyMP4's Video Enhancer tool to upscale the iMovie video to 4K before uploading.
Q: What format does iMovie export?
A: iMovie can export to MP4, QuickTime MOV, AVI, Image Sequence, and DV.
Q: Why won't QuickTime open an MP4 from iMovie?
A: MP4 is just the container that can hold various video and audio codecs. You can open only the MPEG files (.mp4, .m4v, .m4a, .mp3, .mpg) via QuickTime. So, you should convert iMovie MP4 files to QuickTime-supported formats.
Q: What is the best video editing software as an alternative to iMovie?
A: AnyMP4 Video Editor is one of the iMovie replacements, offering video, audio, and image editing with over 200 customizable effects (filters, transitions, titles, and elements) and ready-made templates. It is the best alternative to iMovie for editing videos, video tutorials, game recordings, etc.
Q: How to import MP4 files into iMovie?
A: MP4 is a container format that can hold many codecs, such as MPEG-4, MPEG-2, H.264, Theora, VP8, DivX, XviD, AAC, Vorbis, etc. Only MP4 files encoded with MPEG-4/AAC or H.264/AAC can be recognized by iMovie. First, convert the MP4 file with AnyMP4 Video Converter Ultimate to MPEG-4/AAC or H.264/AAC, then drag the MP4 file into iMovie.
