Video Compressor MP4, MOV

Compress a video for free on your iPhone or iPad. Set a target size in MB or GB, then check the result before sharing. Your original stays untouched.

A video too large to send can still be worth keeping. Video Compressor creates a separate MP4 or MOV copy on your iPhone or iPad, leaving the original untouched. Import from Photos or Files, compress video, then compare the result before you save or share it.

Choose a quality preset, change the output resolution or enter a target file size in MB or GB. This video size reducer shows an estimate before you start. The target file size is a guide, not an exact promise; motion, sound and duration all affect the result.

Use the MP4 compressor to re-encode compatible clips as H.264, or choose MOV for the output. You can keep the audio or mute it. To reduce video size further, try a lower resolution or quality setting. The app never enlarges a video's resolution.

A smaller video file is easier to share. Play it back, check its actual size and save it to Photos or Files. Local history lets you reopen completed results. The MP4 compressor also reports when a clip is already well optimized, so you can decide whether the new copy is worth keeping.

The free version lets you compress video one at a time, with all compression settings available; ads may appear. Lifetime Pro is a one-time purchase that removes ads and unlocks batch compression for up to 10 videos, processed in order. Completed results stay available if a later item fails.

Video Compressor uses local compression: your videos are not uploaded to our servers. Ads, purchases and optional usage analytics may use the internet. You can turn analytics off in Settings; it never includes videos or filenames.

Keep the app open while processing. An interrupted job may need to restart. A video size reducer cannot make every clip smaller: an already optimized video may grow. Check the final size when you reduce video size, then keep the copy that suits you.
