Cropper: Vertical Video Editor

Cropper turns any landscape video into a perfectly framed vertical clip — ready for Instagram Reels, TikTok, and YouTube Shorts. No cloud uploads. No watermarks. Nothing ever leaves your phone.

Built by a working broadcast cinematographer for creators who actually care about how their footage looks.

WHY CROPPER

Most reframing apps quietly upload your footage to their servers, slap on a watermark, and make you create an account. Cropper does none of that. Every single frame is processed on your device using Apple's Vision framework — your video never touches the cloud, no sign-up is required, and free exports are completely watermark-free. It's faster, it's private, and it works even in airplane mode.

THREE WAYS TO FOLLOW YOUR SUBJECT

Cropper gives you full control over how the frame follows the action:

Hand — drag anywhere on the canvas to nudge the crop manually for quick, hands-on adjustments.
Keyframe — tap to drop a static crop center, or drag to paint a continuous path that the crop follows over time.
Track — tap directly on a person or object and let Apple Vision lock on and follow it automatically, frame by frame.
Mix and match all three on the same clip. Pinch with two fingers to pan and zoom at the same time, recording smooth 3-axis motion (X, Y, and zoom) in a single pass.

CINEMATIC KEYFRAME TRANSITIONS

Control exactly how the crop travels between keyframes:

Movie — holds, then cuts cleanly at the keyframe. Cinematic and deliberate.
Sport — holds, then snaps with a fast pan. Built for high-energy action.
Smooth — glides gradually between keyframes. Ideal for talking heads, interviews, and tutorials.
LIVE BEFORE / AFTER PREVIEW

See precisely what your final video will look like before you export — no guesswork, no surprises. Choose your enhancement level:

Off — keep your original look untouched.
Light — a subtle, natural lift.
Auto — smart, balanced grading in one tap.
Manual — full hands-on control over Brightness, Contrast, Saturation, Warmth, Sharpening, and Denoise.
A split before/after view updates live as you adjust, so you always know exactly what you're shipping.

IMPORT FROM ANYWHERE

Bring in any video from your Photos library, iCloud Drive, Google Drive, Dropbox, or OneDrive. When you're done, export in 9:16, 1:1, or 16:9 and save straight to your camera roll — sharp, clean, and ready to post.
