One-tap video resizer with presets for Instagram video size, TikTok, YouTube Shorts, Moments and more. Smart auto-crop follows people & objects, background fill removes black bars, 4K export — everything runs on your iPhone. Nothing is uploaded.
From quick 9:16 crops to cinematic reframing — a complete toolkit, on your phone.
Crop video to 9:16, 1:1, 4:5, 16:9, 21:9 or free-form, plus one-tap TikTok video crop presets for Reels, Shorts, Douyin, Moments, Xiaohongshu, YouTube and more — the video resizer for every platform.
Vision-powered subject detection automatically frames people and objects — static composition or live follow while exporting.
Remove black bars with video background blur, mirror, stretch or color fills when converting landscape to portrait. Choose what looks best.
Frame-to-frame motion analysis smooths handheld footage, and smart follow interpolates between keyframes for silky pans.
Straighten tilted footage at any angle, rotate, flip, pinch-zoom, free-form window — the same feel as the system Photos crop.
Export up to 2160p with H.264 or HEVC, resolution and quality presets, and true WYSIWYG preview before you save.
Choose from Photos or Files — any resolution, any orientation. iCloud and cloud drives work too.
Tap a ratio or platform preset, or let Smart Auto-Crop frame the subject. Refine with zoom, rotate, straighten and fill.
Watch a true-to-output preview, pick resolution up to 4K, then export. The result matches what you saw.
