Cropzen

Cropzen is a simple video cropper and video trimmer for your phone. Crop and resize video with zero watermark, then trim and shorten your clips. Crop video to 9:16, 1:1, 4:5 or 16:9 in a few taps.

Drop in any clip and reframe it for the feed you’re posting to. Pinch to zoom, drag to position, snap to a preset, and export. There’s no timeline to learn and nothing to sign up for, and your videos never leave your device.

Ready-made sizes for where you post: 9:16 vertical for Instagram, TikTok and YouTube; 4:5 and 1:1 for an Instagram feed post; 16:9 for YouTube.

FAQ
How do I crop a video for a post?
Tap 4:5 or 1:1 for a feed post, or 9:16 for vertical video, then drag the frame over what matters and export.

Can I edit several clips at once?
Yes. Video batch crop applies one aspect ratio to a whole set of clips with Pro.

Is my video uploaded anywhere?
No. Every edit and export runs on your phone.
