Cropper: Vertical Video Editor

Cropper is the vertical video editor for Reels, TikTok, and YouTube Shorts.

Wide 16:9 does not fit a phone. Cropper fixes that with your finger — not a timeline, not a cloud upload. Drag a gold 9:16 crop over the player, the host, the product, the play. Slow to 0.5×. Pinch to zoom. Export on this Android. Every frame stays on the device.

The app is free forever with a Made with Cropper watermark. Cropper Pro removes it: $4.99/month, $19.99/year (save ~67%), or $99.99 lifetime. Cancel anytime in Google Play.

ONE FINGER. FOLLOW THE PLAY.

Load a match, an interview, a runway shot. Set 0.5× (or 0.25× for fast action). One finger pans the crop while playback runs — the path is recorded. Two fingers pinch in or spread out. Paused, a drag just repositions.

Movie, Sport, or Smooth controls how the crop travels. Sport for a snap pan. Smooth for a glide. Movie for a hold-then-cut. Zero timeline clutter.

HAND, KEYFRAME, TRACK, DUAL VIEW

• Hand — live pan and zoom while the clip plays

• Keyframe — tap who should fill the frame; taps use your Default transition (Movie / Sport / Smooth)

• Track — tap a subject; on-device vision follows them forward

• Dual View — two crops in one 9:16 for podcasts, interviews, and reaction cams, with a thin separator

Reframe landscape into a deliberate vertical shot — not a blind center cut.

CLOSED CAPTIONS ON THE PHONE

Karaoke-style captions with Whisper. Nothing is sent to a server.

• Speech-to-text on this phone

• Edit every line; add, delete, or insert

• CapCut-style looks: Highlight, Bounce, Paint, Comic Book, and more

• Drag captions on the After preview — including onto the Dual View seam

• English by default, Auto detect, or any listed language

TRIM, JOIN, ENHANCE, EXPORT

Mark In and Out (Out starts at the end of the clip). Join two or more videos from Photos or Files. Choose 9:16, 1:1, or 16:9. Enhance on export starts Off — turn on Light, Auto, or Manual when a clip needs grade.

Export at Source size (fast, native detail) or Max quality (up to 4K with Pro). Add your own logo. Free exports include a centered Made with Cropper watermark; Pro removes it.

WHY CROPPER

Most “crop for Reels” apps auto-center the frame, upload your footage, or hide the work in a desktop timeline. Cropper is finger-first and private. Built by Rocco Contini — broadcast cinematographer and solo maker at After Video Inc.

No ads. No account required to edit. Airplane mode still works.
