How to Compress MOV Files Online

  1. Upload Your MOV Files: Click "+ Add Files" to select MOV files from your computer, Google Drive, or Dropbox. Batch upload supported — compress multiple iPhone recordings at once.
  2. Choose Compression Settings: Set a target file size percentage (e.g., 50% of original), specific size in MB, or adjust quality level. Optionally reduce resolution (4K → 1080p, 1080p → 720p) for further savings.
  3. Download Compressed Files: Click "Compress" and download your smaller MOV files.

Why Compress MOV Files?

iPhone and Mac Recordings

MOV is the default recording format on iPhone and Mac (QuickTime). A 1-minute 4K iPhone video is ~350MB. Compressing to 50% saves ~175MB per minute — significant for long recordings.

Email and Sharing

Most email services limit attachments to 25MB. A 30-second iPhone video can exceed this. Compressing makes MOV files practical for email, messaging apps, and cloud sharing.

iCloud and Storage

iPhone photos and videos consume iCloud storage quickly. Compressing MOV files before backing up can save gigabytes of cloud storage.

Social Media Uploads

Instagram, TikTok, and other platforms re-compress uploaded video anyway. Pre-compressing your MOV files gives you more control over quality and speeds up the upload process.

Frequently Asked Questions

How much can I reduce a MOV file?

Typically 30-60% at the same resolution with moderate quality settings. Reducing resolution (4K → 1080p) can achieve 70-80% reduction. iPhone 4K video has significant room for compression.

Does compressing reduce quality?

Yes — lowering quality settings removes video data. At 60-70% quality, the difference is minimal on phone and laptop screens. Noticeable on large 4K displays at close viewing distance.

Should I compress or convert to MP4?

If you need to stay in MOV format (Apple editing workflows), compress. If format doesn't matter, converting to MP4 gives even better compression with broader compatibility.

Can I compress multiple MOV files at once?

Yes. Upload multiple files and compress them all with the same settings.

Will metadata (date, location) be preserved?

Video metadata is preserved during compression.

Is it free?

Yes. Completely free with no watermarks, no sign-up required, and no file count limits.

Does it work on mobile?

Yes. Works in any modern browser on all devices — no app installation required.
