Why Video Compressor

On-device and private

Your videos never leave your iPhone. There is no server, no account, and nothing is uploaded.

Set an exact size

Aim for an exact target in megabytes, or pick a simple quality level. See the estimate before you compress.

No watermark, ever

The output is clean. Unlike many converters, we never stamp your video.

More than shrinking

Resize, trim, remove audio, convert MOV to MP4, and compress several videos in a batch.

How it works

  1. Pick a video from your photo library.
  2. Choose a quality level or an exact target file size.
  3. Tap Compress. Everything runs on your device.
  4. Save the smaller video to Photos or share it anywhere.
