Free Video Cropper

Crop landscape videos to 9:16 portrait for phones, or add a light watermark. Runs entirely in your browser, no uploads.

Converts 1920×1080 landscape to 1080×1920 portrait — perfect for wallpapers, TikTok, and Reels.

Adds a subtle semi-transparent text overlay so you can brand your videos without cluttering them.

All processing happens locally using FFmpeg WebAssembly. Your videos never leave your device.
