Crop Video
Crop a video with a live preview — square, vertical 9:16, 16:9 presets or free per-edge sliders, all on your device.
Why crop video boundaries & reframe social media footage?
Converting landscape horizontal footage into vertical mobile formats or removing unwanted visual clutter from video edges is an essential video editing step:
- Reframe Landscape Video for TikTok & Reels (9:16): Crop horizontal 16:9 camera recordings into vertical 9:16 videos optimized for mobile smartphone feeds.
- Crop Out Taskbars & Desktop Windows: Trim unwanted operating system taskbars, browser tabs, or webcam overlays off screen recordings.
- Remove Watermarks & Corner Logos: Crop away annoying corner watermarks, timestamps, or unwanted background clutter.
- Live First-Frame Visual Preview: Inspect your exact crop box boundaries on a live canvas preview before starting video encoding.
FFmpeg WebAssembly video crop filter engine
ToolJiffy uses a high-performance client-side FFmpeg WebAssembly pipeline:
The engine applies FFmpeg’s crop=w:h:x:y video filter in browser memory, calculating precise pixel offsets from your selected aspect preset or edge percentage sliders before outputting a clean MP4 file.
Client-side security for private video clips
Uploading private family videos, corporate presentation recordings, or unreleased content to third-party cloud video tools creates severe privacy risks.
ToolJiffy operates on a zero-cloud architecture. By leveraging client-side WebAssembly, video cropping runs 100% locally in your browser memory. Your video files never touch external cloud servers.
