How to Convert MOV to MP4
To convert MOV to MP4, upload your .mov file above, select MP4, and download a video that plays on Windows, Android, browsers, smart TVs, and every social platform. MOV is Apple's recording default, but its support outside Apple devices is unreliable — MP4 (H.264/AAC) is the universal interchange format. For typical iPhone footage, the conversion preserves visual quality while often shrinking the file.

JoltFile desktop appHow to convert MOV to MP4 in 5 steps
The whole process takes under two minutes and requires no software installation or account. Your original MOV file is never modified.
Upload your MOV file
Drag your .mov file onto the converter above, or click “Browse files” to select it from your device. Files are processed locally in your browser whenever possible — nothing is uploaded to a server.
Confirm the output format is MP4
The converter defaults to MOV → MP4 on this page. If you dropped in a different file type, set the target format to MP4 (.mp4) using the format menu.
Adjust quality settings
Pick a resolution and quality preset. 'High' keeps the source resolution and is visually transparent; lower presets shrink the file for messaging and email.
Convert the file
Click “Convert”. JoltFile processes the file and shows a progress indicator — most video conversions finish in a few seconds.
Download your MP4 file
Save the converted .mp4 file to your device. The original MOV file is never modified, and temporary data is discarded automatically.
What happens to quality when converting MOV to MP4?
Re-encoding MOV to MP4 with H.264 at a high quality setting (CRF 18–20 equivalent) is visually lossless for practical purposes. Files recorded with editing codecs like ProRes shrink dramatically — often 80–95%. Audio converts to AAC. Note that ProRes alpha channels and some multi-track layouts don't survive the move to standard MP4.
When should you convert MOV to MP4?
- Sharing iPhone or camera footage with non-Apple users
- Uploading video to social platforms and websites
- Playing recordings on smart TVs and game consoles
- Shrinking ProRes exports into shareable files

About the MOV and MP4 formats
What is MOV? (QuickTime File Format)
MOV is Apple's QuickTime container format, introduced in 1991 and still the default recording format for iPhones and many professional cameras. It supports high-quality codecs (including ProRes) and alpha channels, which keeps it popular in editing workflows.
Strengths
- Native to macOS/iOS and professional cameras
- Supports ProRes and other editing-grade codecs
- Can carry alpha-channel (transparent) video
- Multi-track support for professional workflows
Limitations
- Patchy support on Windows, Android, and web browsers
- Larger files than equivalent MP4 when using editing codecs
- Many upload forms reject .mov
What is MP4? (MPEG-4 Part 14)
MP4 is the most universally supported video container format, standardized by MPEG in 2001. Almost always paired with H.264 or H.265 video and AAC audio, it plays natively on every modern browser, phone, TV, and social platform.
Strengths
- Plays on virtually every device and platform
- Excellent quality-to-size ratio with H.264/H.265
- Supports subtitles, chapters, and multiple audio tracks
- Required or preferred by every major social platform
Limitations
- Lossy — re-encoding always costs quality
- Not ideal for professional editing (intra-frame codecs win there)
- H.265 variants can fail on older hardware
MOV to MP4 conversion: your questions answered
Will converting MOV to MP4 reduce video quality?
Only imperceptibly at high quality settings. MOV is a container — if your footage uses H.264 inside, some tools can even remux it into MP4 with zero re-encoding and zero quality loss.
Why is my MOV file so much bigger than the MP4?
iPhones and professional cameras often record MOV with editing-grade codecs (ProRes, high-bitrate HEVC) designed for post-production, not sharing. MP4 with H.264/H.265 targets delivery, so the same clip can shrink 80% or more.
Can Windows play MOV files without converting?
Sometimes — Windows 11's Media Player handles many MOV files, and VLC plays nearly all of them. But browsers, TVs, and upload forms are far less forgiving, which is why MP4 conversion is the safe default.
Is it free to convert MOV to MP4 with JoltFile?
Yes. JoltFile's free tier covers everyday MOV to MP4 conversions with no account and no watermarks. Higher file-size limits and batch processing are planned for the upcoming Pro tier.
Is my MOV file private when I convert it?
Yes. JoltFile is designed around browser-based processing: whenever technically possible your file is converted locally on your own device and never uploaded to a server. Files that do require server processing are encrypted in transit and deleted automatically after conversion.
