How to convert MOV to MP4 online
Drop your video
Select or drag in any MOV, MKV, AVI, or WebM file. Processing is local — nothing is sent to a server.
Auto-convert
By default FFmpeg remuxes the file without touching quality. Pick High, Balanced or Small to re-encode for a smaller file, or cap the resolution at 1080p, 720p or 480p.
Download MP4
Check the size before and after, then download. Changed your mind on quality? Re-convert the same file without uploading it again.
Why convert MOV to MP4?
Universal compatibility
MP4 plays on every device, browser, and platform — Windows, Android, smart TVs, and social media all accept it without plugins.
Smaller file size
MOV files from iPhones and QuickTime can be large. Converting to MP4 often shrinks the file without visible quality loss.
Upload to any platform
YouTube, Vimeo, Twitter/X, LinkedIn, and most CMSs only accept MP4. Converting beforehand avoids upload errors or automatic re-encoding.
Edit in any software
MOV can cause compatibility issues in Windows-based editors. MP4 is accepted everywhere — Premiere, DaVinci Resolve, Final Cut, and more.
Frequently Asked Questions
How do I convert MOV to MP4 online for free?
Drop your MOV file into the converter or click to browse. The tool converts it locally in your browser — no upload, no sign-up, no watermark. Click Download when done.
Will I lose video quality?
For most MOV files the converter remuxes without re-encoding — zero quality loss. If the codec isn't MP4-compatible it falls back to H.264 + AAC, which is visually lossless.
Is my video uploaded to a server?
No. Everything runs locally in your browser using FFmpeg compiled to WebAssembly. Your video never leaves your device.
What other formats can I convert to MP4?
Besides MOV, the tool accepts MKV, AVI, WebM, and most other common video formats. Output is always MP4.
Why can't QuickTime Player export MP4?
QuickTime's 'Export As' menu saves .mov files regardless of what it says. For a real MP4 you need a converter like this one, iMovie, or HandBrake.
