Document conversions are best-effort. Complex layouts, fonts, comments, tracked changes, and form fields may change in the output.
Structured data conversions preserve the data where possible, but key ordering, comments, quoting, and XML-specific details may change in the output.

Frequently Asked Questions
Why convert MOV to MP4?
MOV works well in Apple and editing workflows, but MP4 is easier to play, upload, share, and import across Windows, Android, browsers, social platforms, messaging apps, and smart TVs.
Can I convert iPhone or QuickTime MOV files to MP4?
Yes. Upload MOV files from iPhone, QuickTime exports, Mac screen recordings, cameras, or editors and convert them to MP4 directly in your browser.
How do I convert a .MOV file to MP4 online?
Upload the .mov file, choose MP4 as the output format, start the conversion, and download the finished MP4 video. You do not need to install QuickTime, Adobe software, or a desktop converter.
Is this MOV to MP4 converter free?
Yes. Convertr lets you convert MOV to MP4 online for free with no registration, no watermark, no software to install, and no limit on how many files you convert.
Is there a file size limit for MOV to MP4 conversion?
You can upload MOV files up to 1 GB each. If your MOV video is over 1 GB, reduce or trim it first, then upload the smaller file for conversion.
Will MP4 be more compatible than MOV?
Usually yes. MP4 is one of the most widely supported video formats for playback, uploads, sharing, and delivery, so it is often the safer output when a MOV file will not open or upload smoothly.
Will converting MOV to MP4 reduce file size?
It often can. MP4 is commonly used for efficient delivery and may produce a smaller, easier-to-share file, though the exact result depends on the source codec, bitrate, resolution, and conversion settings.
Can I convert multiple MOV files to MP4?
Yes. You can upload and convert multiple MOV files in the same browser workflow. Each individual file can be up to 1 GB.
Are my MOV files private?
Files are processed securely and automatically deleted after conversion. Your videos are not kept for long-term storage.

What happens when MOV becomes MP4
Target format
MP4 is a widely supported media container, commonly carrying H.264 or H.265 video and AAC audio.
What changes
The MOV container is read and the selected video and audio streams are written into a MP4 container.
Codecs may be transcoded even when the visible resolution and duration stay the same.
- What is preserved
- Duration, frame order, and visible dimensions are preserved unless you select trimming, frame-rate, or resolution changes.
- What may be lost
- Extra subtitle, attachment, chapter, or alternate audio tracks may be omitted when the target container or selected settings do not support them.
- Codec and quality implications
- Container names do not guarantee a codec. Quality and compatibility depend on the selected video codec, audio codec, bitrate, frame rate, and resolution.
- Realistic limitations
- A valid MOV extension does not guarantee that every codec inside the container is decodable. Corrupt, encrypted, or unusual streams can fail.
Conversion steps
- Upload a MOV file no larger than 1 GB.
- Confirm that MP4 is selected as the target.
- Open settings only if you need to change codec, quality, bitrate, frame rate, resolution, or audio behavior.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the MP4 file and check the result before deleting your source.
Troubleshooting
- The MOV file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The MP4 file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- The result has no sound or will not play.
- Try a broadly supported target codec and verify that the source contains a decodable audio stream.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
