FastSaveMedia's free online video cropper lets you crop, trim and resize videos directly in your browser. Whether you need to convert a horizontal video to vertical 9:16 for TikTok, create a perfect square 1:1 video for Instagram, or adjust to 4:5 for Facebook feed posts – our tool handles it all without requiring any software installation or account signup.
Unlike traditional video editors that require expensive software downloads, or cloud-based tools that upload your private videos to remote servers, FastSaveMedia processes everything locally in your browser using cutting-edge WebAssembly technology. This means your videos never leave your device, ensuring complete privacy and security while delivering faster processing speeds.
The 9:16 vertical format is essential for TikTok, Instagram Reels, and YouTube Shorts. Our video cropper automatically converts horizontal 16:9 videos into vertical 9:16 format by centering the crop area. You can also manually adjust the crop position to ensure the most important part of your video is in frame.
Square videos perform better in Instagram feeds and get more engagement. Select the 1:1 preset to instantly crop your video into a perfect square format. The tool intelligently centers the crop area, and you can fine-tune the position with our manual crop tool.
The 4:5 portrait aspect ratio takes up more screen real estate in Facebook and Instagram feeds, leading to higher engagement rates. Use our 4:5 preset to resize your videos for maximum social media impact.
Need a specific crop that doesn't match standard presets? Use our visual custom crop tool to drag and resize the crop box to any dimensions. Perfect for removing unwanted borders, letterboxing, or focusing on a specific subject in your video.
